Hi,
I would appreciate some help on the following issue that is 100% reproducible with two DHT libraries and several power sources:
regardless of which of the two DHT libraries I use and regardless of which USB power adapters I use I always get "dht timeout waiting for start signal low pulse" error (or equivalent) if I'm not using computer as power source.
But I have no issues if powered from my PC or from RasPi.
Some additional info:
- Model: MKR 1010 (ESP32)
- I have a no name DHT22
- I used pins 0 and then 10 as data pins
- I used DHTesp (GitHub - beegee-tokyo/DHTesp: Optimized DHT library for ESP32/ESP8266 using Arduino framework) and Adafruit DHT libraries
I'm adding the sketch.
Thank you!
Cheers, G
