Product description

Si7021 Temperature and Humidity Sensor I2C Interface 
Product Features:
The module integrates a high quality Si7021 temperature and humidity sensor from Silicon lab, applying specialized digital module acquisition technology and temperature and humidity sensing technology to ensure the product has high reliability and long-term stability. Built-in humidity (moisture-sensitive capacitor) and temperature (thermistor) sensor elements, analog-to-digital converter, signal processing, calibration data and I2C host interface. Factory calibration data is stored in on-chip non-volatile memory, which ensures that the sensors are fully interchangeable and do not require recalibration or software changes. Patented technology for humidity sensing using industry-standard, low dielectric constant polymer dielectrics creates a low-power, monolithic CMOS sensor module with low excursion and hysteresis and excellent long-term stability. Suitable for measuring humidity, dew point and temperature, the module's small size and accuracy of ±0.4°C allows users to embed it in many highly integrated environments. With milliseconds measurement conversion time, no waiting between the start of the measurement and read data, 2.54mm pitch interface, easy to integrate the test.
