M5Stack ENV Pro Unit is a compact BME688 environmental sensor built as an air quality sensor module for projects that need temperature, humidity, pressure, and gas sensing in one device. This VOC gas sensor is easy to use as an indoor air quality monitor for smart homes, weather nodes, and portable IoT builds. Description M5Stack ENV Pro Unit uses the Bosch chip as a BME688 environmental sensor and delivers a compact air quality sensor module with VOC, temperature, humidity, and pressure sensing. If we need a VOC gas sensor and an indoor air quality monitor in the same Grove accessory, M5Stack ENV Pro Unit is the cleanest fit. Features M5Stack ENV Pro Unit combines a BME688 environmental sensor with a compact Grove form factor. This air quality sensor module measures temperature, humidity, pressure, and VOC-related gas changes. The VOC gas sensor helps us build a better indoor air quality monitor than a basic climate-only sensor. M5Stack ENV Pro Unit is easy to deploy in smart home, desktop, and portable monitoring projects.
