Description:

  • DHT11 is a very popular and very low-cost digital temperature and humidity sensor.
  • It uses a capacitive humidity sensor, and a thermostat to measure the surrounding air temperature.
  • The result is available via a digital signal on the data pin (no analog input pins needed).
  • It’s fairly simple to use but requires careful timing to grab data.
  • The only real downside of this sensor is you can only get new data from it once every 2 seconds. But, for most applications, this is not an issue at all.
