Smoke detection alarms are used to prevent fires by monitoring the concentration of smoke. When the concentration of smoke exceeds the limit, the smoke sensor will issue a sound and light alarm, and output a 433MHz wireless signal.
Smoke detectors are widely used in many fields including urban security, residential communities, factories, companies, schools, homes, villas, warehouses, resources, petroleum, chemical industry, gas distribution, and more. They are sensitive to smoke, so they have prevented many fires from happening!
