What is a Gas Sensor?
A device that measures the presence and concentration of gases that are colorless and odorless and cannot be noticed by the human senses.
There are various detection methods, and they are used depending on the type and concentration of the gas being measured.

|---|---|---|---|
| How gas detection works | A mechanism that measures the change in electrical conductivity caused by the reaction between a detection element kept at a high temperature by passing an electric current through it and a gas (semiconductor) or the change in element temperature caused by contact with gas (catalytic/thermal conduction type) | A mechanism that electrolyzes gas at a specific potential on a noble metal catalyst electrode and measures the electrolytic current generated at that time. | Mechanism for identifying the type of gas and measuring its concentration based on the wavelength difference and absorption amount of the infrared absorption spectrum of the gas |

gas sensors using MEMS technology
MEMS technology is an abbreviation for Micro Electro Mechanical Systems, and is a microfabrication technology used in semiconductor manufacturing.
We were one of the first to apply this technology to gas sensors , and have successfully developed a MEMS gas sensors for combustible gas using our unique technology.
We are currently working to expand our lineup of gas sensors that apply this technology.
Advantages of MEMS technology
- Solid-state sensor can consume less power
- The sensor itself can be miniaturized, making it possible to install it in small devices.
- Low cost and excellent mass production
