The DHT21 digital temperature sensor is one of the commonest from the range of DHT temperature sensors and boasts a relatively high temperature measurement accuracy of 0.5oC in 0.1oC 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. 

Specifications:

  • Power supply: 3.3-5V DC
  • Output signal: digital signal via single-bus
  • Wiring: Red-VCC, Yellow-SDA, Black-GND
  • Sensing element: Polymer humidity capacitor
  • Measuring range: humidity 0-100%RH; temperature -40~80Celsius
  • Accuracy: humidity +-3%RH(Max +-5%RH); temperature <+-1Celsius
  • Resolution or sensitivity: humidity 0.1%RH; temperature 0.1Celsius
  • Repeatability: humidity +-1%RH; temperature +-0.2Celsius
  • Humidity hysteresis: +-0.3%RH
  • Long-term Stability: +-0.5%RH/year
  • Sensing period: Average: 2s
  • Dimensions size: 59x27x13.5mm
