ESP8266 + Temperature & Humidity Sensors + Innacuracy measur
Posted: Mon Oct 09, 2017 2:45 pmHi,
first time that i post here.
If i connect DHT22 sensor to a ESP01 or WEMOS D1 Pro or ESP01-S with the example script i have as output temperature or humidity over serial monitor different if i use the same DHT22 Sensor with a Raspberry pi and a Python script. Usually with the ESP i have 2 degree over same measure with the raspberry 2 minutes later..
I tried with a SHT31..some think..how can be possibile? I compare the temperature with a Oregon Scientific Sensor and a other Temperature Sensor; the temperature measured with raspberry pi and DHT22 and SHT31 it's quiet same of Oregon, with ESP i have 2 degree and sometime 1,5 degree upper.
