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.

This product is EOL now, we've released the updated version ENV III Unit with Temperature Humidity Air Pressure Sensor (SHT30+QMP6988) which is fully compatible with this product.
