The smoke sensor alarm monitors the concentration of smoke to achieve fire prevention. When the smoke concentration exceeds the limit, a sound and light alarm is generated and the alarm signal is output.
Smoke sensation is widely used in many fields such as urban security, community, factories, companies, schools, homes, villas, warehouses, resources, petroleum, chemical, gas transmission and distribution. It is sensitive to smoke, so it prevents many fires!
