This last is best and detailed in the Positioner Application Note pdf with an excerpt below,. The number of steps to make is given by the additional count needed to make the parameter byte reach zero or overflow to zero if the byte is considered as unsigned. Thus the byte 'FF' hexadecimal requests only one step, 'FE' two steps, and for example 'F9' requests 7 steps.
With my motors each step corresponds to about 0. Using this information I made up a table of Diseqc packets for each rotation direction. For addressing specific ports of the Diseqc switch tune-s2's normal functions are used.
They are called before the motor position commands are sent. Usage of the modified tune-s2 is pretty simple. The only differences are two new cli switches and not needing to give it tuning parameters. This would cause the satellite dish motor on port 1 of the Diseqc switch to step 1 position counter-clockwise.
To send the same command of stepping 1 position counter-clockwise to the other motor,. The stepping argument values 0 through 10 are mapped on a fairly arbitrary set of actual steps. This results from just doing array index look ups in the above packet tables,. Figuring out where the sun is in the sky in terms of an alt-az format is made simple by pysolar.
Figuring out how to turn that position into sequences of steps on the motors is much, much harder. My setup is pointed directly south. So for this example time that means I need to calculate the number of steps required to turn the top altitude motor The hardest part of this is figuring out what kind of pager system you have. I spent a long time trying to decode the local FLEX pager system with decoders that did not support it.
FLEX is not one of them. Scroll down for FLEX. On June 29th dekar told me about his updated fork of multimon, multimonNG , with better error correction and more modulations supported. For the windows users or anyone wanting more info there's a precompiled version and blog post. Make sure to disable all the demodulators you don't need. I think especially ZVEI is quite spammy. This and this is what pocsag sounds like if you're wondering.
When I originally started playing and wrote this there were only a couple options for rtlsdr receivers to use with the multimon decoder. I used patchvonbraun's multimode to save. In the screenshots below the signal is not pocsag. I thought it might be zwei but now I'm not so sure it's even pager data.
Test samples of pocsag that Dekar links on his blog decode just fine. In order to decode the pager data in real time you should use a first-in first-out file fifo. You should be able to run it without editing once you've made that fifo. Make sure to start multimon reading the fifo before you begin GRC and execute the receiver.
To enable the disabled grey block select them and press 'e' 'd to disable. The audio sink is set to pulseaudio "pulse". Unfortunately it turned out my local pagers were all using FLEX , and so not supported by any of the above software.
But the procedures might still be useful for someone. Since the rtlsdr receivers can but shouldn't do 3. I've attempted to start this and you can see a copy here.
A couple days after I wrote the above paragraph zarya came on rtlsdr on freenode and mentioned his rtlsdr supprting FLEX decoder written months before. It is easy to use and works great! Internally it uses gnuradio's optfir to generate low pass taps that wide to use witih a frequency xlating FIR filter. The below output is heavily censored and edited to avoid disclosing or reproducing sensitive information but it gives you an idea of the type of messages. I tried for over a year before successfully decoding local pager signals.
Now that I have I think it is a bad idea. There is far much too much private information in cleartext. I don't plan to try again. These days csete has added in rtlsdr support so you can use his original repository. You will almost certainly not get this error. But, someone might, so I'm leaving it here to be indexed. If you're like me and run an older distribution then your Qt libraries will be out of date and lack a function required for generating the name of the files to be saved when recording.
Initially I thought it was a qtcreator thing so I tried to get more information by doing it manually,. To get it to compile on these systems you'll have to do the below. Ubuntu So, while I was waiting for Qt 4. I removed that function call with a static string of text. If you are using qtcreator like the docs suggest you can double click on the error and go to the line.
If not, it was in. If you're using For LTE Cell Scanner requires cmake 2. Until you open CMakeList. You can see my installation notes before I figured it out. And this is a local backup in case that disappears. Make sure to completely remove the old ITPP 4. When LTE Cell scanner compiles you can go back and restore the. The rate of scan is about 0. LTE Tracker I haven't used as much yet recently released but it is included in the github repository cloned initially and should be compiled as well if you did the above.
Check out the authors site for videos of it's use since an ascii paste of the ncurses like interface wouldn't tell you much. Nobody really expected that you'd use it to build actual applications, but rather just use it as a way of making "test jigs" for your signal flows.
This section is my notes on how I made basic examples work, and how I edited those examples in very simple and often broken ways. Also, since gqrx, multimode, and other intergrated receivers came out I don't see any need to update these as things change. Most of this is very old. While there are links to the originals in the summaries, these descriptions are of the versions modified by me; usually just sample rate and GUI stuff.
While the sample rate or tuner width I set may be some large number, it'll become obvious what the limits of each other as you scan about and see the signal folding or mirroring. Using sample rates above 2. If you're using GNU Radio 3. If it comes with a python file, try that first before generating one from the GRC file. When tuning, make sure to hit enter again if it doesn't work the first time or tunes to the wrong frequency.
Always hit autoscale to start, and for FFT displays try using the "average" settings. I have set all audio sinks to "pulse" pulseaudio instead of say, "hw:0,0" ALSA. You might have to change that. To get a list of hardwareuse "aplay -l". That'll show the various cards and devices. Some flowcharts have variables for it, others put it directly in the Audio Sink element. There are two ways to specify the use of multiple dongles.
Each specified device is seperate with a space from the previous one. The OsmoSDR Source block has extensive help files at the bottom of it's properties if you scroll down.
To enable a block, select it and press 'e'. To disable a block select it and press 'd'. When disabled blocks will appear darker gray. If you open a. If your install is more than a month or two old this often happens. Update GNU Radio. It's easier to type in 1e6 than so use scientific notation when you can in variable fields. If you double click on an element in a flowchart it usually includes a helpful "Documentation:" of most the variables to be set at the bottom.
The GUI element grid position is a set of two pairs of numbers: "y,x,a,b" where the first pair "y,x," is position y row, x column and "a,b" is the span of the box. If you enter a Grid Position and it overlaps with another element it'll turn red and report the error and where the origin is of the element it overlaps with.
Use OsmoSDR source. It's not recommended to use sample rates above 2. In older versions of gr-osmosdr and rtl-sdr I think automagic gain control AGC was on all the time so you didn't have to set the gain explicitly in the source in GRC.
New versions require that and also require setting the chan 0. The dongles seem to have noise at their 0Hz center frequency so the best performance is from selecting a band Khz offset from the center depending on signal type. I don't think it is very simple; it includes many advanced FM specific features like extraction of the 19k pilot tone next to some commercial FM broadcasts.
It used a file source which was decoded to wav and saved to disk. Seen in the screenshot above. Right now the rate of the audio files saved out is But it sounds fine. Seen below. This was the first one I managed to get to work. It's best just to enter the frequency as a number.
I also increased the sample rate to 2. I also remove the superfluous throttle block. This takes parts from a bunch of the other example receivers and repurposes them in presumably incorrect but seemingly working ways. It is a basic example of how to offset the tuner khz away from the center to avoid the noise there.
I started with 2h20's simple tuner's GUI framework and removed almost all of the content. The the bandpass filter is specified in a variable,.
This is done by setting the frequency of the Xlating FIR filter to,. I also made the current frequency display a editable text field so you can tune, copy, and paste.
There are good examples of how notebook positioning works and includes simple scripting examples for the file field. Attach 9. Still, connect the servo to pin 9. Above are the two methods to control the servo. You can choose either one according to your liking or actual need. A stepper motor is an electromechanical device which can convert electrical pulses into discrete mechanical movements. The shaft or spindle of a stepper motor rotates in discrete step increments when electrical command pulses are applied to it in the proper sequence.
The motors rotation has several direct relationships to these applied input pulses. The sequence of the applied pulses is directly related to the direction of motor shafts rotation. The speed of the motor shafts rotation is directly related to the frequency of the input pulses and the length of rotation is directly related to the number of input pulses applied. One of the most significant advantages of a stepper motor is its ability to be accurately controlled in an open loop system.
Open loop control means no feedback information about position is needed. This type of control eliminates the need for expensive sensing and feedback devices such as optical encoders. Your position is known simply by keeping track of the input step pulses. Pyroelectric infrared motion sensor can detect infrared signals from a moving person or moving animal, and output switching signals.
It can be applied to a variety of occasions to detect the movement of human body. Conventional pyroelectric infrared sensors require body pyroelectric infrared detector, professional chip, complex peripheral circuit, so it is more bigger with complex circuit, and lower reliability.
Now we launch this new pyroelectric infrared motion sensor, which is specially designed for Arduino. It uses an integrated digital body pyroelectric infrared sensor, and has smaller size, higher reliability, lower power consumption as well as simpler peripheral circuit. If the sensor detects someone moving nearby, D13 indicator on V4. If no detecting the movement, D13 indicator on V4. This analog gas sensor - MQ2 is used in gas leakage detecting equipment in consumer electronics and industrial markets.
It has high sensitivity and quick response. In addition, the sensitivity can be adjusted by the potentiometer. Digital output data is formatted as bit twos complement and is accessible through either a SPI 3- or 4-wire or I2C digital interface.

It has the advantages of excellent quality, fast response, anti-interference ability and high cost performance. Each DHT11 sensor features extremely accurate calibration data of humidity calibration chamber. The calibration coefficients stored in the OTP program memory, internal sensors detect signals in the process, and we should call these calibration coefficients.
The single-wire serial interface system is integrated to make it quick and easy. Qualities of small size, low power, and meter signal transmission distance make it a widely applied application and even the most demanding one. Convenient connection and special package can be provided according to your need.
Then open the serial monitor and set the baud rate to , you will see the current temperature and humidity value. This is a simple soil humidity sensor aims to detect the soil humidity. If the soil is lack of water, the analog value output by the sensor will decrease; otherwise, it will increase. If you use this sensor to make an automatic watering device, it can detect whether your botany is thirsty so as to prevent it from withering when you go out.
Using the sensor with Arduino controller makes your plant more comfortable and your garden smarter. The soil humidity sensor module is not as complicated as you might think, and if you need to detect the soil in your project, it will be your best choice.
The sensor is set with two probes inserted into the soil, then with the current go through the soil, the sensor will get resistance value by reading the current changes between the two probes and convert such resistance value into moisture content. The higher the moisture less resistance is, the higher conductivity the soil has. The surface of the sensor have undergone metallization process to prolong its service life. Insert it into the soil and then use the AD converter to read it.
With the help of this sensor, the plant can remind of you I need water. Connection for V4. It can be loaded directly into a variety of readers molds. Module uses voltage of 3. Operating Frequency Environmental Operating Temperature degrees Celsius 8.
