Hello, I have a Core and now a Photon as well. I have a working code on the Core for DHT22 to get the temp and hum data. However, flash the same code and hook up the DHT22 to the Photon, I cannot get any data… It is hooked up to D3, gnd and 3v3 pins. Any idea? The code should work from Core on P…

This code works on the Photon without any issues and it’s non-blocking :smile: [image] piettetech/PietteTech_DHT PietteTech_DHT - DHT Sensor Library for Spark Core

Thanks for the reply. I am using this code, which is perfectly fine on core, but not delivering values from photon
