Product Introduction
1. Japan FIGARO Air Quality Sensor (Focus on Methyl Mercaptan) TGS2603 Description:
The sensing element is composed of an integrated heater and a metal oxide semiconductor on an alumina substrate. If the target gas is present in the air, the higher the gas concentration, the higher the sensor's conductivity. With a simple circuit, the change in conductivity can be converted into a signal output corresponding to the gas concentration.
Air Quality SensorsTGS2603 has high sensitivity to low-concentration odors, such as hydrogen sulfide gas from amine series, waste, and spoiled fish food.
By using the change in circuit resistance and its ratio to the resistance in clean air to simulate human perception of polluted air, air quality control is practically achieved.
