The sensing element of Figaro gas sensors is a tin dioxide (SnO2) semiconductorwhich has low conductivity in clean air. In the presence of a detectable gas,the sensor's conductivity increases depending on the gas concentration inthe air. A simple electrical circuit can convert the change in conductivity toan output signal which corresponds to the gas concentration.
The TGS 816 is not only sensitive to a wide range of gases, it also has a ceramicbase which can withstand severe environments up to 200°C. It has highsensitivity to methane, propane, and butane, making it ideal for natural gasand LPG monitoring. The sensor can detect a wide range of gases, making it an excellent, low cost sensor for a variety of applications.
