The GXHTV3 is an ultra-low power, I2C compatible temperature and humidity sensor IC designed for consumer electronics. It offers a wide supply voltage range (1.6V-5.5V), a small DFN6 package (2x2x0.75mm3), and factory calibration with typical accuracies of 3%RH and 0.3C. Its integrated system includes capacitive humidity sensing, PN junction temperature measurement, a 16-bit ADC, digital signal processing, calibration data storage, and an I2C interface. The sensor is suitable for applications requiring miniaturization, low power consumption, and cost-effectiveness, such as consumer electronics, cold chain transportation, smart homes, smart agriculture, communication equipment, and photovoltaic energy storage.
