The circuit shown here is that of the IC controlled emergency light. Its main features are: automatic switching-on of the light on mains failure and battery charger with overcharge protection. When mains is absent, relay RL2 is in deenergised state, feeding battery supply to inverter section via its N/ C contacts and switch S1. The inverter section comprises IC2 (NE555) which is used in stable mode to produce sharp pulses at the rate of 50 Hz for driving the MOSFETs. The output of IC3 is fed to gate of MOSFET (T4) direc ....etc

A system of automatic opening and closing of the door by detecting any movement of the body near the door. This is achieved with the aid of a PIR (infrared passive) sensor. A living body generally emits infrared energy which is detected by the PIR sensor from a considerable distance. This detection signal is fed to a micro-controller to operate a gate motor through the IC motor controller.When a body approaches within the operating range of the sensor, it sends a logic command to open the door. The door closes automatically with a fixed time de ....etc
