DHT11 Temperature and Humidity Sensor

DHT11 Digital Temperature And Humidity Sensor is a basic and low-cost digital temperature and humidity sensor. This sensor is used for projects where accuracy and precision doesn’t play big role. This comes in a blue perforated plastic enclosure. This has four pin. There is an upgraded version of the DHT11 temperature and humidity sensor available, which is DHT22 Sensor with higher sensing ranges.

The sensor uses a capacitive humidity sensor and a thermistor based temperature sensor to measure the ambient humidity and temperature. The humidity sensing ranges from 20% to 90% with ±5% accuracy and the temperature sensing ranges from 0 degrees to the 50 degrees Celsius with ±2°C accuracy. The sampling time of this sensor is 2 seconds almost. This Temperature and Humidity Sensor uses digital pins to communicate with the microcontroller unit and does not have any kind of analog pins. This sensor is also available as module.
