FIGARO PRODUCT INFORMATION TGS 816 - for the detection of Combustible Gases Features: * General purpose sensor with sensitivity to a wide range of combustible gases * High sensitivity to methane, propane, and butane * Long life and low cost * Ceramic base resistant to severe environment Applications: * Domestic gas leak detectors and alarms * Portable gas detectors The sensing element of Figaro gas sensors is a tin dioxide (SnO2) semiconductor which has low conductivity in clean air.
In the presence of a detectable gas, the sensor's conductivity increases depending on the gas concentration in the air.
A simple electrical circuit can convert the change in conductivity to an output signal ...
