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.
Pin Connection
- Pin 1: Power +Ve (3.3VDC to 5.5VDC Max wrt. GND)
- Pin 2: Serial Data Output
- Pin 3: Power Ground or Power –Ve
Features
- Very reliable and Stable for long term
- Easy to use with different microcontroller boards.
- It is precisely factory calibrated.
