I have done two more tests letting the sensor measure once every minute: The first time it hung up after 39 measurements, the second time after 51. I havent checked the concrete error on the board yet, but I assume I am just getting some cryptic error code meaning "cant find/talk to device". As far ...

Well what can I say, it works :D ! Hard to say how happy that makes me right now! After soldering I just let it run for about 15 mins measuring every 3 seconds and always got a correct response from the AM2320, using the D3 and D4 pins. Thank you everyone for your help :) and especially mcauser for ...

Is there a chance the board's Pins are not properly connected that way? The chance is more to the opposite. For almost sure you have connection problems, if you do not solder the headers to the Wemos board. Oh, okay sounds like I have something to do on the weekend then ^^. Will report back, thank ...

The headers have been hand-soldered in place by you, right? Have you checked the relevant headers have a good joint like... https://learn.adafruit.com/adafruit-guide-excellent-soldering/common-problems Thanks for your response. I have not soldered anything yet, should I? I just plugged the headers ...

Ah cool, I did not realize that parameter was there. I just gave it a try, but for all frequencies it still does not find anything... sigh. I have two other sensors but I think none of them are I2C compatible - DSB1820 https://www.amazon.de/gp/product/B013GB27HS - DHT22/AM2302 https://www.amazon.de/...

Hi mcauser, thanks for your advice and all the background info, I really do appreciate that you took the time! This evening was full of learning and a bit of frustration. Before I saw your comment I tried a setup very similar to what you used here https://github.com/mcauser/MicroPython-ESP8266-DHT-N...

Thanks Peter, will get those and report back

Hi Frida and thanks for your response, it really helps. Now looking at it it is blatantly obvious and a bit embarassing really. The cables are correct though, I just got the markers mixed up in the image. I have now corrected that, thanks for pointing out. Okay so I will figure out what those pull u...

Hi everyone, I am trying to connect an ESP8226 chip (~ Wemos D1 Mini) running Micropython to an AM2320 temperature/humidity sensor. I would like to make a few "remote sensors" that way and hook them up to small web app on a Pi to monitor that data across the house over the year. I am having trouble ...

I am getting results back from the AM2320 sensor using your library :) However it is very unstable, e.g. for measuring every 10 seconds this is a typical result: 22.4, 32.7, 0.0, 32.0, 0.0, 32.0, 0.0, 32.0, 0.0, 32.0, [Errno 110] ETIMEDOUT [Errno 110] ETIMEDOUT [Errno 110] ETIMEDOUT ... First value ...
