The smoke sensor alarm implements fire prevention by monitoring the concentration of smoke. When the concentration of smoke exceeds the limit, the smoke sensor generates an audible and visual alarm and outputs an alarm signal.
Smoke sensing is widely used in many fields such as urban security, communities, factories, companies, schools, homes, villas, warehouses, resources, petroleum, chemical, gas transmission and distribution. Sensitive to smoke, so many fires have been prevented!
