GY213V SI7021 Temperature and Humidity Sensor Module

Description:
The module is designed for accurate measurement of humidity and temperature. The sensor is equipped with Si7021 chip with an I2C interface, which provides industrial accuracy of measurements.
The chip contains an analog-to-digital signal processing converter, calibration data, and an I2C interface.
This module is easy to use temperature and humidity sensor with the supply voltage from 3 V to 5 V.
It communicates through an I2C interface. The accuracy is 0.4 °C for temperatures ranging from -10 °C to 85 °C and 3% for the humidity in the range from 0 % to 80 % RH. The sensor is used in meteorological stations and systems of control of the conditions in the premises.
