Gravity: H2 Sensor - module with a hydrogen concentration sensor

A sensor used to detect pollutants in the air by measuring gases such as hydrogen, ethanol and carbon monoxide. It is used in various areas, such as the food industry, chemical industry, air quality control in laboratories and environmental monitoring. Figaro TGS2600

Volatile gas sensor module, including LPG, natural gas, natural gas

Digital gas sensor solution that senses a wide range of Total Volatile Organic Compounds (TVOCs), including equivalent carbon dioxide (eCO2) and metal oxide (MOX) levels, intended for indoor air quality monitoring in personal devices such as watches and phones, but we’ve put it on a breakout board so you can use it as a regular I2C device.

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.
