Si7021 temperature and humidity sensor high precision I2C interface industrial

Description

Product Introduction
From Silicon lab module integrates high quality Si7021 temperature and humidity sensors, a dedicated application module collects digital technology and temperature and humidity sensing technology, to ensure that products with high reliability and excellent long term stability. Built humidity and temperature sensor element, an analog-digital converter, signal processing, calibration data and I2C master interface. Industry-standard, low-k dielectric polymer humidity sensor patented technology to create a low-power, single-chip CMOS sensor module having a deviation and low hysteresis and excellent long-term stability. Suitable for measuring humidity, temperature and dew point, small module size, accuracy up to ± 0.4 ℃, the user can embed many highly integrated environment. It has a conversion time measured in milliseconds, between the start measurement without waiting for the read data, 2.54mm pitch interface to facilitate integration testing.
