DHT11 Temperature and humidity sensor

So, I just bought two DHT11 sensors for a small project. From the specifications:

  • Humidity from 20-80% humidity readings with 5% accuracy
  • 0-50°C temperature readings ±2°C accuracy

After wiring them up on my breadboard, I find the following:

  • DHT11 (number one) reports 20% humidity and 20 degrees celsius
  • DHT11 (number two) reports 30% humidity and 24 degrees celsius

    In other words – I got two sensors reporting within accuracy range, but with maximum deviation in both directions.
    I guess I should be pleased – provided both sensors would be placed at the same location, the combined readings would provide me with something very close to reality…
