Features & Compatibility
The DHT22 (AM2302) is a basic, low-cost digital temperature and humidity sensor designed for accurate environmental monitoring. It uses a capacitive humidity sensor and a thermistor to measure ambient conditions and provides a calibrated digital signal via a single data pin—no analog input required.
This sensor is simple to use and well-suited for DIY electronics, Arduino projects, and home automation systems. It offers excellent long-term stability and requires no additional components to operate. The only limitation is its 2-second data refresh rate, meaning readings may be slightly delayed.
Features
- High precision capacitive sensing
- Full-range temperature compensation
- Calibrated digital signal output
- Long transmission distance
- Low power consumption
- Outstanding long-term stability
- 4-pin package, fully interchangeable
- No extra components required
