  • CM2302 / DHT22 TEMPERATURE & HUMIDITY SENSOR MODULE

    Product code:

    WPSE345

    Description:
    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.
    Features:
    1. ultra-low power consumption
    2. long transmission distance
    3. standard digital single bus output
    4. excellent long-term stability
    5. high-precision NTC
