Product Introduction
KGS 102 is a SnO₂ semiconductor gas sensor widely used in gas detection, air purification systems, automatic ventilation systems, microwave ovens and other equipment.
In a clean environment, the sensor resistance is high.
However, as the concentration of water vapor or gas in the atmosphere increases, the resistance decreases.
The KGS 102 gas sensor features excellent resistance to airflow, extremely fast response speed, and outstanding durability.

The variation in resistance of the sensor(Rs) is measured as a change in the voltage across the load resistor(RL). The sensor resistance (Rs) is calculated from output voltage(VRL) by the following formula.
Rs = (Vc / VRL- 1) x RL
