CM2302/DHT22 Temperature & Humidity Sensor Module

• Ultra-low power consumption
• Long transmission distance
• Standard digital single bus output
• Excellent long-term stability
• High-precision NTC

The CM2302/DHT22 Temperature & Humidity Sensor Module is a composite sensor that uses dedicated digital module acquisition technology and temperature and humidity sensing technology to ensure high reliability and excellent long-term stability. It includes a capacitive wet sensor and a high-precision NTC temperature sensor connected to a high-performance 8-bit microcontroller, resulting in excellent quality, fast response, anti-interference ability and cost efficiency. Each sensor is calibrated in a highly accurate humidity calibration room.

In comparison to the DHT11, this sensor is more precise, more accurate and works in a wider range of temperature/humidity, but it is larger and more expensive.
