DHT22 Temperature and Humidity Sensor

DHT22 Temperature and Humidity Sensor

DHT22 is an advanced temperature and humidity sensor that provides calibrated digital signal output. It offers high reliability and stability for long-term operations. This sensor includes an 8-bit microcontroller that delivers fast and accurate responses.

The sensor can measure temperature in the range of -40 to 80°C with an accuracy of ±1°C and humidity in the range of 0-100% with an accuracy of ±5% RH. Due to the sensor's data collection period, measurement results can be obtained in 2-second intervals. It is slightly larger in size compared to the DHT21 model.

Dht22 Temperature and Humidity Sensor Features:

• It is a high-performance model of the DHT series.
• Provides digital output.
• Operating Voltage: 3.3-5 VDC
• Measurement Range:
  • Humidity: 0-100% RH
  • Temperature: -40 - 80 °C
• Accuracy:
  • Humidity: +/- %3 (Max %5) RH
  • Temperature: < +/- 1°C
• Measurement Period: 2 seconds
• Product Dimensions: 22x28x5 mm

NOTE: A pull-up resistor is required between Vcc and the output pin. Therefore, it is recommended to use a resistor between 4.7K and 10K. Since the DHT11 model shares similar features, an application made with one model can also be applied to the other.
