DHT-11 Temperature And Humidity Sensor Module

DHT-11 Temperature and Humidity Sensor Module

The DHT-11 is a versatile Humidity and Temperature Sensor capable of generating calibrated digital output. It can seamlessly interface with various microcontrollers such as Arduino, Raspberry Pi, and more, providing instantaneous results. Known for its affordability, the DHT-11 offers high reliability and long-term stability.

Utilizing a capacitive humidity sensor and a thermistor, the DHT-11 accurately measures the surrounding air conditions and delivers a digital signal via the data pin, eliminating the need for analog input pins. Its simplicity is further enhanced by the availability of libraries and sample codes for popular platforms like Arduino and Raspberry Pi.

This module simplifies the connection process of the DHT-11 sensor to an Arduino or microcontroller by integrating the pull-up resistor required for sensor operation. Merely three connections—VCC, GND, and Output—are necessary to utilize the sensor effectively, streamlining the setup process for users.
