Generally, the gas sensor could be divided as 4 kinds such as the electric chemical type, the semi-conductor type, the optic type, the catalytic. The application of each sensor type is quite different. It is important to adopt the proper gas sensor depend on the gas type, environmental factor in the using area, sensing range, resolving ability, cost, etc. Senko Co., Ltd is trying to provide the most proper gas sensor and modules depend on customers” requests, keeping lots of the technology development and Know How related with the gas sensor.
- The carbon dioxide sensor module sequenced with the air conditioner
- The smell sensor module for home appliance (TVOC sensor adopted)
- Hydrogen detecting module for the fuel battery
- Electric sensor transmitter only for the electric chemical sensor type
- Concentrated Oxygen Sensor Modules for the Oxygen Generator
- Concentrated Odor sensor module
- Module related with the electronic nose
