AM2301 DHT21 Temperature And Humidity Sensor

AM2301/DHT21 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.

Features:

• 4-pin package.
• Ultra-low-power.
• No additional components.
• Excellent long-term stability.
• All calibration, digital output.
• Completely interchangeable.
• Long-distance signal transmission.
• Relative humidity and temperature measurement.

Package Includes:

1 x AM2301 Temperature & Humidity Sensor.
