DESCRIPTION
This Temperature Humidity Sensor DHT22 uses a capacitive humidity sensor, and a thermistor to measure the surrounding air temperature. The result is available via a digital signal on the data pin. What is good about digital signal is that the signal will not decay over long distances.
The downside of this sensor is that you can only get new data from it once every second.
TECHNICAL DETAILS
- Input Voltage: 3.3 - 5V
- Temperature Range: -40°C to 80°C
- Temperature Accuracy: ± 0.5°C
- Humidity Range: 0 - 100%
- Humidity Accuracy: ± 2%
SHIPPING LIST
- 1x Temperature Humidity Sensor DHT22 / AM2302
