DHT21 AM2301 Temperature and Humidity Sensor

Description:

The DHT21 digital temperature sensor is one of the most common of its kind. It has a relatively high-temperature measurement accuracy of 0.5C to 0.1C steps with a relative humidity accuracy of +/- 3%

It has only 3 wires, 2 for power and 1 for output. One digital pin is required to interface it to a microcontroller. It is very well suited for common development boards like Arduino, NodeMCU, STM32 etc.

Features:

• Accurate and durable
• 4 pin package
• Ultra-low power
• No additional components
• Stable
• All calibration, digital output
• Completely interchangeable
• Long-distance signal transmission
• Relative humidity and temperature measurement

Specifications:

• Power: DC 3.3-5.2V
• HUMI: 0 ~ 99.9% RH
• TEMP: -40 ~ 80C
• Precision: 3% RH, 0.5C
• Output: Digital (1 wire)
• Dimension: 60 x 27 x 14mm (L x W x H)
