AM2302/AM2302B Single-bus Digital Temperature & Humidity Sensor

The M2302B is a composite sensor designed to measure temperature and humidity, providing a calibrated digital signal output. It utilizes advanced digital module aggregation technology and state-of-the-art temperature and humidity sensing technology to deliver high reliability and long-term stability. The sensor features a capacitive humidity sensing element and a highly accurate temperature sensor, all integrated with a high-performance 8-bit microcontroller.

Key benefits of the M2302B include excellent quality, rapid response time, strong anti-interference capabilities, and great cost-effectiveness. Each sensor is calibrated in a precision humidity calibration chamber, with calibration coefficients stored in the microcontroller and applied during internal signal processing. The standard single-bus interface allows for easy integration with other systems. With its ultra-compact size, low power consumption, and a signal transmission range of over 20 meters, this sensor is ideal for a wide range of applications and challenging environments. It can be easily connected using just three cables.
