DHT11 Humidity and Temperature Sensor Module

DHT11 Humidity and Temperature Sensor Module

The DHT11 Humidity and Temperature Sensor Module, commonly referred to as the dht11 sensor, is capable of sensing both temperature as well as humidity. This makes it ideal for DIY electronics projects and automation systems using platforms like Arduino and Raspberry Pi.

The output of the dht 11 temperature sensor module is in the form of a digital signal on a single data pin. The sensing update frequency is measured every 2 seconds (0.5Hz). The DHT11 Sensor Module can be easily interfaced with any microcontroller such as Arduino, Raspberry Pi, and others.

This sensor module integrates the dht 11 sensor and other required components on a compact PCB. The DHT11 sensor includes a resistive-type humidity measurement component, an NTC temperature measurement component, and a high-performance 8-bit microcontroller inside, delivering calibrated digital signal output.

The module offers high reliability and excellent long-term stability, thanks to its advanced digital signal acquisition technique and temperature & humidity sensing technology.
