This datasheet describes the Aosong AM2322 digital humidity and temperature sensor, detailing its electrical characteristics, application ranges, and…
The AM2322 is a digital humidity and temperature sensor that provides calibrated digital signal output. It combines a capacitive humidity sensing element with a high-precision integrated temperature measuring element connected to a high-performance microprocessor. The sensor offers excellent reliability, long-term stability, low power consumption, and high cost-performance. It supports both single-wire and standard I2C communication interfaces, allowing for easy system integration without the need for additional wiring or secondary calculations for temperature compensation. This manual is written in Chinese.
The sensor operates normally between 0% and 80% relative humidity and -40°C to 80°C.
The activation time should not exceed 10% of the measurement time, with a suggestion to measure once every 2 seconds.
Recommended materials include metals, LCP, POM, PTFE, PE, PEEK, PP, PB, PPS, PSU, PVDF, and PVF.
