by Velleman

CM2302 is a temperature and humidity composite sensor. It uses dedicated digital module acquisition technology and temperature and humidity sensing technology to ensure high reliability and excellent long-term stability.

The sensor includes a capacitive wet sensor and a high-precision NTC temperature sensor connected to a high-performance 8-bit microcontroller, ensuring the product's excellent quality, fast response, anti-interference ability and cost efficiency. Each sensor is being calibrated in a highly accurate humidity calibration room.

Compared to the DHT11, this sensor is more precise, more accurate and works in a bigger range of temperature/humidity, but its larger and more expensive.
