Gas sensor helps detect the presence of various toxic and combustible gases in the environment. 

We prepared a complete guide for gas sensor, explained different operating principles and applications fields and compared all gas grove sensors. 

Seeed Gas Sensor Selection Guide

The interaction between the test gas and the sensing surface can be detected by the measurements of change in resistance, capacitance, work function, mass, optical characteristics etc.

There are a numerous use of these gas sensors, playing important roles in various sectors including industry, medical, environmental applications, and domestic applications for monitoring toxic and flammable gases. 

The most common use for gas sensor is monitoring toxic gases present in the atmosphere. 

You can use Grove – Air Quality Sensor v1.3 to detect alcohol and smoke in the air. We also have Grove- Alcohol Sensor help you with specific Alcohol detection, check Alcohol Detection Project on Hackster.io

Safety at work

Gas sensor is important for keep your safety during work. It helps control indoor air quality; monitor toxic gases in a working environment, for instance in a factory where dangerous chemicals are used

Grove – Gas Sensor(MQ2) can detect LPG, i-butane, propane, methane, alcohol, Hydrogen and smoke to keep you safe. 

Domestic safety/household application 

In order to detect poisonous gases or smoke in households and avoid loss due to accidents such as fires and explosions; intelligent refrigera­tor or oven; fire alarm; natural gas heating; leak detection; air quality control; air purifiers; cooking control, a sensitive smoke alarm is especially important to every household. 

Grove – Gas Sensor(MQ9) is high sensitive to carbon monoxide and CH4,LPG. And Grove – Temperature, Humidity, Pressure and Gas Sensor (BME680) will be a all-in-one sensor for your both outdoor and indoor projects,. 

Safety in car Public security  

Besides environmental projects, you can choose gas sensor for car ventilation control; gasoline vapor detection; alcohol breath tests. 

You can start with Grove – Gas Sensor(MQ3) with High sensitivity to alcohol and small sensitivity to Benzine, Grove – Gas Sensor(O2), and Grove – Alcohol Sensor for car safety projects

It is also listed in the complete gas sensor guide about how gas sensor works for medical, agricultural, industrial areas and food quality control , utilities aerospace.

Grove makes it easier to connect, experiment, and simplify the prototyping process. No jumpers or soldering required. We have developed more than 220 Grove modules, more Groves are coming soon covering a wider range of applications that can fulfill a variety of needs. 

Free feel to let us know what you want to see in the future for Grove in the forum. We hear and will take action!
