KGS 101 气体传感器是氧化锡(SnO2) 半导体式气体传感器。用于气体探测器、空气清净器,自动换气系统,微波炉等。传感器的电阻在洁净的空气中虽高，但在大气中的气体或水蒸气的浓度增加，传感器的电阻就减小. KGS 101 具有优异的稳定性，快速响应恢复, 高灵敏度,耐久性优秀的特点。

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 formular.
|
|
|
Rs = (Vc / VRL -1) x RL
