The DHT22 humidity sensor comes in an ideal plastic body for mounting on a panel or similar. It uses a capacitive sensor that returns a digital signal with the measurement.
This sensor, unlike DHT11, is capable of measuring negative temperature values and measuring tenths of a degree.
- Operating voltage: 3 to 5.5 VDC
- Humidity measurement range: 0-100% ± 2% accuracy
- Temperature measurement range: -40ºC to 80ºC ± 0.5º of accuracy
- Maximum sampling rate: 2 seconds
