The DHT-11 Digital Temperature And Humidity Sensor is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin (no analog input pins needed).

Its 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, so in your code please use sensor reading interval at 2 seconds or more. Compared to the DHT22, this sensor is less precise, less accurate and works in a smaller range of temperature/humidity.

But despite its disadvantages over DHT22, it is smaller and less expensive sensor for temperature and humidity measurement.

Note: This package does not include Arduino board, you have to buy it separately.

  5. Prabir KC (verified owner)

    DHT 11 connects to the D4 pin on an ESP8266. It is not identical to DHT 22. One needs to keep this in mind- otherwise recording temperature and humidity will be difficult. However very cheap and delivered very fast

    best quality product.

  7. adisworld (verified owner)

    Use this product for small project because it is less accurate than DHT22. Nice product, good quality, working well. Very Fast shipping.
