DHT22

450.00 Br

  • Operating Voltage: 3.5V to 5.5V
  • Operating current: 0.3mA (measuring) 60uA (standby)
  • Output: Serial data
  • Temperature Range: -40°C to 80°C
  • Humidity Range: 0% to 100%
  • Resolution: Temperature and Humidity both are 16-bit
  • Accuracy: ±0.5°C and ±1%
  • The DHT22 is a commonly used Temperature and humidity sensor. The sensor comes with a dedicated NTC to measure temperature and an 8-bit microcontroller to output the values of temperature and humidity as serial data. The sensor is also factory calibrated and hence easy to interface with other microcontrollers.
  • The sensor can measure temperature from -40°C to 80°C and humidity from 0% to 100% with an accuracy of ±1°C and ±1%. So if you are looking to measure in this range then this sensor might be the right choice for you.

Applications

  • Measure temperature and humidity
  • Local Weather station
