This is a gas sensor that has high sensitivity to refrigerant gases widely used in air conditioning and refrigeration equipment, including A2L refrigerant gases and A3 refrigerant gases.
The gas sensor consists of a metal oxide semiconductor formed on an alumina substrate along with an integrated heater. When detectable gases are present, the conductivity of the sensor increases as the concentration of that gas in the air rises. Using a simple electrical circuit, this change in conductivity can be converted into an output signal corresponding to the gas concentration. The TGS2630 is a gas sensor that has high sensitivity to mildly flammable (A2L) refrigerant gases such as R-32 and R-1234yf, as well as highly flammable (A3) refrigerant gases like R-290 (propane), in addition to widely used refrigerants like R-404a and R-410a in air conditioning and refrigeration equipment. It has a built-in filter material, which results in low sensitivity to volatile alcohols (interfering gases in residential environments), thus demonstrating high selectivity for mildly flammable (A2L) refrigerant gases. Due to the small size of the gas sensing element, a heater current of 56mA is sufficient for the TGS2630.
