Specifications

Product Introduction

The AM2320 digital temperature and humidity sensor is a composite sensor with calibrated digital signal output. It employs dedicated temperature and humidity acquisition technology to ensure high reliability and excellent long-term stability. The sensor consists of a capacitive humidity sensing element and a high-precision integrated temperature measuring element, connected to a high-performance microprocessor. It features excellent quality, ultra-fast response, strong anti-interference capability, and high cost-effectiveness.

The AM2320 supports two communication methods: single-bus and standard I2C. The standard single-bus interface makes system integration simple and quick. Its ultra-small size, extremely low power consumption, and signal transmission distance of up to 20 meters make it the best choice for various applications, even the most demanding ones. The I2C communication method uses standard communication timing, allowing users to directly connect to the I2C bus without additional wiring. Both communication methods directly output temperature-compensated humidity, temperature, and CRC check digital information, so users do not need to perform secondary calculations or temperature compensation to obtain accurate temperature and humidity data. The two communication methods can be freely switched, providing flexibility and convenience for a wide range of applications. The product features a 4-pin connection for easy installation, and special packaging forms can be provided according to user requirements.
