Circuit diagram of smoke detector

WebJan 15, 2013 · This photoelectric smoke detector circuit uses one LED and 2 LDRs to detect the smoke and sound an alarm. The LM1801 IC is the best choice for this circuit because we need a few external components and is used in almost any smoke alarm. The whole photoelectric smoke detector circuit is powered from the 220V mains supply. WebDescription. Here is a simple fire alarm circuit based on a Light Dependent Resistor (LDR) and lamp pair for sensing the fire. The alarm works by sensing the smoke produced during fire. The circuit produces an audible alarm when the fire breaks out with smoke. When there is no smoke the light from the bulb will be directly falling on the LDR.
