What is a Gas Sensor? Construction, Types & Working of Gas ...

04/06/2019· The type of gas the sensor could detect depends on the sensing material present inside the sensor. Normally these sensors are available as modules with comparators as shown above. These comparators can be set for a particular threshold value of gas concentration. When the concentration of the gas exceeds this threshold the digital pin goes high. The analog pin can be used to measure the concentration of the gas.

The selection and use of flammable gas detectors

14 In many fixed gas detection systems, the sensor units are designed to use natural diffusion as the sampling method. The sensors are located at or near points where there is the possibility of a gas release. 15 However, natural diffusion as a sampling method can be slow. In many cases a faster response is needed, and the sample is transported to the sensor using a sampling pump. This is ...
