Si7021 Industrial High Precision Humidity Sensor I2C Interface for Arduino US

Description

The module integrates the high quality Si7021 temperature and humidity sensor from Silicon Lab, and applies the special digital module acquisition technology and temperature and humidity sensing technology to ensure the product has extremely high reliability and excellent long-term stability. Built-in humidity and temperature sensor elements, analog to digital converter, signal processing, calibration data and I2C host interface. Using industry-standard, low dielectric constant polymer dielectric for humidity sensing, the patented technology creates a low-power, single-chip CMOS sensor module with low deviation and hysteresis and excellent long-term stability. Suitable for measuring humidity, dew point and temperature, the module is small in size and accurate up to ±0.4℃. Users can embed it in many highly integrated environments. Millisecond measurement conversion time, no need to wait between starting measurement and reading data, 2.54mm distance interface, easy to integrate the test.
