Description

AM2301 Capacitive Digital Temperature & Humidity sensor is one of the commonest from the range of DHT temperature sensors; and boasts a relatively high-temperature measurement accuracy of 0.5°C in 0.1°C steps with a relative humidity accuracy of ± 3%.

It has only 3 wires, including power and ground, meaning only one digital pin is required to interface it to a microcontroller. For Arduino development platforms the sensor is very well supported by the DHT library available from the Arduino Playground website.

Note: This package does not include the Arduino board.

Features:

1. 4-pin package.
2. Ultra-low-power.
3. No additional components.
4. Excellent long-term stability.
5. All calibration, digital output.
6. Completely interchangeable.
7. Long-distance signal transmission.
8. Relative humidity and temperature measurement.
