The sensor is designed for indoor air quality testing. The main gas detected is carbon monoxide, alcohol, acetone, thinner, formaldehyde and other slightly toxic gases. It is compatible with 5V and 3.3V power supply. Seeed Studio 101020078
The module with an alcohol sensor (MQ-3), allows you to measure the concentration of ethanol in the air. The module has an analogue output and an output triggered by exceeding the threshold of sensitivity.
Bosch Sensortec\'s BME688 development kit enables testing of applications based on temperature, barometric pressure, humidity, and gas detection. The first AI-enabled environmental sensor, the BME688 can distinguish between different gas compositions by analyzing their "electronic fingerprints." The kit is configurable using BME AI-Studio software, which optimizes performance and power consumption, and the eight-sensor board enables testing of multiple configurations simultaneously.
