Purchase was easy and shipping was very fast with great tracking. Hooked this up to a breadboard that I also tested the parallax microwave doppler, and another brand from China on. This one had some problems. It sends a continuous signal and doesn't stop, even when there's no motion. I checked the hook up wires to the board and they are correct. Not sure why it's doing this. I used the same exact program and ardiuno uno microprocessor as for the parallax and china models. It might be something in the programming, not sure, but as of right now, I am not able to use this 'tindie' sensor. Hopefully it just needs an adjustment somewhere, maybe in the programming. I did take notice the difference in sensor structure, this one being an HB100 and the other two being GH-719. Not sure if that has anything to do with it. **It would be extremely helpful if the seller could post some simple testing code for arduino.**
I'm very sorry about your experience and would have wished you'd have contacted me before to request assistance for your project, as I'd be more than happy to help you. I'll provide a sample code on this page soon.
Could you double check your complete setup? You should get the exact same behavior shown in the demonstration video. Because of the way the Doppler effect works, the only reason for a given output signal frequency is the speed of the object moving in front of the sensor.
Hello. Good delivery, good design. I did not try the module yet. On the board is written VOUT and FOUT. I presume that those signals are prop to the speed. But could somebody tell me if VOUT = 5VDC -----> SPEED (MPH), or if FOUT = 32 Hz ------> SPEED (MPH) ? Thanks for your support ! Best regards,
Thanks for the review! It'd be actually odd if it came from Germany as I'm located in Switzerland :). The devices are sent from Switzerland or China depending on current stock and destination... I'll edit the product description to reflect that.
Does what it says. No documentation by author, but it's self-explanatory. The documentation about the ESP8266-03 can be found on the Internet. There could be a switch to enable programming mode, but this can easily be added manually with the included breadboard.
The breakout module works great - as expected. It would be even nicer, if the ESP8266 could be removed from the action breakout board. (This may not be possible with the SMD version of the board however) One could then use it to prepare multiple modules for deployment.
Later on I actually thought I could maybe put 2x2.0mm headers close enough so they could have good electrical contacts with the esp8266. However doing so may involve going with through hole headers as SMT ones wouldn't be positioned well enough.
The documentation on the website was a big help. Experimenting with the AT commands was easy. But i wanted to play with the SDK, so after a few changes to the configuration settings, i had my first program uploaded and running. Thanks again for this board! It makes playing with the ESP8266 a lot easier.
PS: i did not contact the seller, so the rating about the communication is unknown, but i had to enter something.
