ENV II
SKU:U001-B
Description
ENV II is an environmental sensor which can sense temperature, humidity and atmospheric pressure. It integrates the SHT30 and BMP280 sensors and is programmed over the I2C protocol(SHT30:0x44, BMP280:0x76).
SHT30 is a digital temperature and humidity sensor with high precision and low power consumption.
BMP280 is an absolute barometric pressure sensor which is especially designed for mobile applications. It offers the highest flexibility to optimize the device regarding power consumption, resolution and filter performance.
