DHT11 Temperature and Relative Humidity Sensor Module


C-3, R-5 , I-1


Product ID: 2090 SKU: sen-2090 Categories: , Tags: , , ,

The DHT11 is a relatively cheap sensor for measuring temperature and humidity. This article describes a small library for reading both from the sensor. The DHT22 is similar to the DHT11 and has greater accuracy. However, this library is not suitable for the DHT21 orDHT22 as they have a different data format. Check DHTlib for support of these sensors.
