Description
- M5Stack ENV Pro Unit w/ Temperature, Humidity, Pressure, Gas Sensor (BME688)
- Measures a wide range of environmental parameters including VOCs, IAQ, temperature, humidity, and pressure
- Compact design with a wide operating range and simple communication interface
- Improved model with added VOC measurement and gas scanning capabilities
- Customizable gas scanning functionality to meet specific application requirements
The M5Stack ENV Pro Unit w/ Temperature, Humidity, Pressure, Gas Sensor (BME688) is an advanced environmental sensor that employs the BME688 sensor solution. This unit is capable of measuring a wide range of environmental parameters, including volatile organic compounds (VOCs), indoor air quality (IAQ), temperature, humidity, and atmospheric pressure.
The compact design of this unit, coupled with its wide operating range and simple communication interface (I2C), makes it an excellent choice for various applications. These include weather stations, indoor environmental monitoring, and air quality detection. The unit is designed to operate in a wide range of conditions, from 300 hPa to 1100 hPa of pressure, 0% to 100% humidity, and -40 to 85 °C temperature. This makes it suitable for use in diverse environments, from sea-level to high-altitude regions, and under various extreme conditions such as dryness, humidity, cold, and heat.
The M5Stack ENV Pro Unit is an improvement over the previous ENV series products. It not only measures temperature, humidity, and atmospheric pressure but also includes the capability to measure VOCs and perform gas scanning. This unit offers exceptional sensitivity, with a detection range that extends down to the parts per billion (ppb) level.
The gas scanning functionality of this unit can be customized to meet specific application requirements in terms of sensitivity, selectivity, data rate, and power consumption. The BME AI-Studio tool can be used to train the ENV Pro Unit for specific applications such as home appliances, IoT products, or smart homes.
The unit provides digital output of various data parameters such as air quality index (IAQ), volatile organic compounds (VOC) and CO2 equivalent (ppm), gas scanning results (%), and intensity level (%). This feature facilitates AI data analysis.
