AM2301 Capacitive Digital Temperature and Humidity Sensor
The AM2301 Capacitive Digital Temperature and Humidity Sensor is a widely-used DHT sensor renowned for its high-temperature measurement precision of 0.5°C in 0.1°C steps and a relative humidity precision of ±3%.
This sensor features just three wires—power, ground, and data—requiring only a single digital pin for connection to a microcontroller. The DHT library available on the Arduino Playground website provides robust support for this sensor on Arduino platforms.
