Product Description
Product Overview
The GXHTC3 is a highly integrated temperature and humidity sensor IC designed for consumer electronics applications. It offers ultra-low power consumption, I2C protocol compatibility, and a wide supply voltage range (1.6V-5.5V), making it ideal for battery-powered devices. The sensor features factory calibration, a miniaturized DFN6 package (2x2x0.75mm), and typical accuracy of 3 %RH and 0.3 C. Its applications span consumer electronics, cold chain transportation, smart home, smart agriculture, communication equipment, and photovoltaic energy storage.
