AM2301A Temperature & Humidity Sensor

The AM2301 or also known as DHT21 digital temperature sensor is one of the common from the range of DHT Temperature & Humidity sensors and boasts a relatively high temperature measurement accuracy of ±0.3℃ better compared to the DHT11 or DHT22 and 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.

Module Aspects:

• Accurate,durable and high quality
• 4 pin package
• Ultra low power
• No additional components
