Does anyone know if its possible to calibrate a DHT11 humidity/temperature sensor, specifically the temperature element?
Based on other thermostats and temperature sensors it is reading about 2 degrees C high i.e. 23 deg C instead of 21 deg C.
Alternatively, is there a way I can factor in an adjustment to the sketch so the temperature reported in the Arduino Temp device in Vera UI15 is reported 2 degrees lower?
I've tried amending the code in the sketch as per below but this only changes the values printed to the serial monitor and not the device in Vera.
Serial.println(temperature - 2.0); // adjusted as reading 2 degrees C higher than room thermostat
I'm a noob when it comes to Arduino, programming and Vera so please bear with me...
