NodeMCU & Espruino & DHT22
Posted: Sat Nov 14, 2015 3:01 amHi,
I've tried to put together a dead simple thing: a DHT22 sensor connected directly to a NodeMCU v0.9 board.
I've connected wires according to sample page:
1 - 3V3
2 - D1 - GPIO5
3 OR 4 - GND (I've tried both version)
I tried the sample code of the modul. I always get -1 for both temperature and humidity.
I have to admit that this is my first excursion to the world electronics and espruino and I'm not able to figure out what the problem is.
Any idea?
