This sensor module utilizes DHT11 as the sensitive component and has a bypass capacitor and a pull-up resistor on-board. The DHT11 is a pre-calibrated digital output temperature and humidity sensor, with fixing bolt holes for easy installation.
The single-wire wiring scheme makes it easy to be integrated to other application,and the simple communication protocol can reduce the programming effort required. It can detect the temperature and humidity of the surrounding environment.
