Temperature and Humidity Sensor – ASAIR AM2301B (−40 to +80°C, 0–100% RH)

The ASAIR AM2301B temperature and humidity sensor is a high-performance RH/T sensor module engineered for precision, durability, and long-term stability. It integrates a newly designed ASIC dedicated chip, an improved MEMS semiconductor capacitive humidity sensor, and a standard on-chip temperature sensor, ensuring highly accurate digital measurements.

Compared to earlier generations, the AM2301B offers significantly enhanced reliability and stability, making it suitable for industrial, commercial, and DIY applications. Each humidity sensor is factory-calibrated and rigorously tested to ensure consistent performance across its full operating range of −40°C to +80°C temperature and 0–100% RH humidity.

The sensor’s protective structural design helps shield internal components from environmental stress, while integrated mounting holes allow easy installation in multiple scenarios. With a fast response time, strong anti-interference capability, and digital I²C output, the AM2301B is an ideal temperature and humidity sensor for modern embedded systems and IoT solutions.
