GXHT31 Temperature and Humidity Sensor
■GXHT31 is the next generation of single-chip integrated temperature and humidity sensor developed by Beijing Galaxy-CAS Technology. It was developed based on the extremely weak signal detection design platform and MEMS process design platform of Beijing Galaxy-CAS Technology. Integrating high-sensitivity MEMS moisture-sensitive components on silicon-based CMOS wafers can reduce the interference of multi-chip signal transmission, reduce chip area, and improve packaging reliability. It has two user-selectable I2C addresses, the I2C communication speed is up to 1MHz, and the chip is packaged in a miniaturized DFN package with an outline size of 2.5 x 2.5 mm2 and a height of 0.9 mm. This enables the GXHT31 to be integrated in various applications. In addition, the wide power supply voltage range of 2.2~5.5V makes it adaptable to various power supply environments.
