Gas Sensor
Gas Sensor
Gas leak sensing is the procedure of identifying hazardous gas leaks using high-end sensors to provide safety to place and people. Gas sensor is a device developed using an audible alarm to aware people when a dangerous gas is leaked and detected. This is widely used in the domains of fuel filling, construction, painting, fumigation, excavation of soils, confined spaces, landfill operations, etc. This is appropriate for detecting LPG, CH4, H2, CO, Alcohol, Propane or any other harmful gas. With high sensitivity and quick response time, this ensures prompt detection to provide time to people to evacuate the space and safe themselves. Its sensitivity can be adjusted by using potentiometer. This sensor has analog resistance to provide maximum output.
