the smoke detector is a thing that detects the smoke by intensity variation of that area under control. if any fire occurs there the light intensity on that area decreases. this can be measured my photo metric method.Photometric measurement is based on photodetectors, devices (of several types) that produce an electric signal when exposed to light. Simple applications of this technology include switching luminaires on and off based on ambient light conditions, and light meters, used to measure the total amount of light incident on a point.its o/p will be in mV.
