AM2301 Capacitive Digital Temperature and Humidity Sensor
The AM2301 Capacitive Digital Temperature and Humidity Sensor is a popular DHT sensor known for its accurate temperature measurement with a precision of ±0.5°C in 0.1°C steps and a relative humidity accuracy of ±3%.
This sensor simplifies wiring with just three connections: power, ground, and data. It only requires a single digital pin on a microcontroller for operation. Full support for the AM2301 is available through the DHT library on the Arduino Playground, making it easy to integrate with Arduino platforms.
Example Arduino Sketch, Library, and Datasheet available on our support forum here.
Note: This package does not include the Arduino board.
