DHT-11 Temperature and Humidity Sensor Module
The DHT-11 is a versatile humidity and temperature sensor that provides calibrated digital output. It easily interfaces with various microcontrollers, including Arduino and Raspberry Pi, delivering instant results. Renowned for its affordability, the DHT-11 is also reliable and stable over the long term.
Featuring a capacitive humidity sensor and a thermistor, the DHT-11 accurately measures environmental conditions and sends digital signals through the data pin, eliminating the need for analog inputs. Its user-friendly design is supported by readily available libraries and sample codes for popular platforms like Arduino and Raspberry Pi.
The module simplifies connections by integrating the necessary pull-up resistor for operation. Users only need to connect three pins—VCC, GND, and Output—making setup quick and straightforward.
