DHT11 Humidity and Temperature Sensor Module
The DHT11 Humidity and Temperature Sensor Module is capable of sensing both temperatures as well as humidity. This makes it ideal for projects as well as automation. The board is also equipped with a high-performance 8-Bit microcontroller connected to the DHT11 sensor module.
The output of the DHT11 Temperature Sensor Module is in the form of a digital signal on a single data pin. The sensing update frequency is to be measured every 2sec (0.5Hz). The DHT11 Sensor Module can be interfaced with any microcontroller like Arduino, Raspberry Pi, etc.
This Sensor module integrates the DHT11 sensor and other required components on a small PCB. The DHT11 sensor includes a resistive-type humidity measurement component, an NTC temperature measurement component, and a high-performance 8-bit microcontroller inside, and it provides calibrated digital signal output.
The Module has high reliability and excellent long-term stability, thanks to the exclusive digital signal acquisition technique and temperature & humidity sensing technology.
