[0002] There are many kinds of alarms, the most commonly used of which is the smoke sensor. The smoke alarm is a common fire safety device. The function of the smoke alarm is to detect the smoke concentration. When the smoke concentration in the environment where the smoke alarm is located is higher than a certain limit, an alarm signal will be issued or a sprinkler mechanism will be activated to extinguish the fire. Smoke alarms are mostly installed in public buildings such as shopping malls and schools. The composition of smoke is a mixture of gases produced by combustion and some fine particles, and the temperature of smoke is higher than the ambient temperature, so the density is smaller than that of air, so smoke will flow upwards after it is generated.
