Where there’s smoke, there’sfire and we usually don’t amuse ourselves with the idea of having a fire anywhere else other than a fireplace. So, we equip ourselves with an arsenal of early detection sensors that can help avert a potential disaster to life and property. One of the chief whistleblowers in this assortment of accident prevention devices is the smoke detector, which we can often see as round perforated plastic disks, fixed to the ceilings of offices and homes.  A smoke detector, in all its simplicity, detects smoke in its surroundings and sounds an alarm. These are one of the most important safety devices in an establishment especially in homes, where it is one of the few sensors which can provide safety 24×7. The alarm issued may manifest itself as a Blinking LED, an Audio siren, or in case of establishments connected with a central monitoring station, an alert on the management screens in the control room.
