DHT22 air temperature and humidity sensor (replacement for AM2302) with serial digital data output.
The sensor is based on the AHT30 sensor from ASAIR and the 8-bit RISC processor FT61E14 from Fremont Micro Devices with a 12-bit analog-to-digital converter.
It is recommended to connect a 10K resistor between the power supply (VCC) and the data pin (DATA) to improve operating stability and reading accuracy.
Specification:
Supply voltage: 3.3 V to 6 VDC (recommended 3.3-5.0VDC)
Temperature measurement from -40 to 80 °C (accuracy +/- 0.5*C)
Humidity measurement 0-100%RH (accuracy +/- 2%).
Average current consumption: 0.2 mA
Dimensions 25.5mm x 15.7mm x 6.4mm (excluding pins), pin length 8mm
