25.8.3 Utilizing Digital DHT11 Humidity/Temperature Sensor
25.8.3.1 Feature of the Sensor
Here, we will use a module that integrates DHT11 sensor and other necessary components on a small PCB as shown below. The DHT11 sensor is equipped with resistive humidity measurement components, NTC temperature measurement components, and a high-performance 8-bit microcontroller and provides precise digital signal output. The DHT11 sensor originally has four wires, but this module has three wires.
