While actually giving in to our body s natural wants such as sleep, we re keeping the balance beam in an upright and neutral position generally a good thing to do. But life comes and calls quite often, many times forcing us to put hunger, drowsiness, and other basic human needs on the back burner in order to seal the deal and get the job done.

So here s the scenario, you re sitting in your car getting ready for a big meeting that if completed will net your company nice little multi-billion dollar deal. You re supposed to be going over ....etc

Abstract

Automatic Night Lamp with Morning Alarm System is a simple yet powerful concept, which uses transistor as a switch. By using this system manual works are 100% removed. It automatically switches ON lights when the sunlight goes below the visible region of our eyes. This is done by a sensor called Light Dependant Resistor (LDR) which senses the light actually like our eyes. It automatically switches OFF lights whenever the sunlight comes, visible to our eyes and activates the morning alarm.

By using this system energy consumption i ....etc

advantage of super sensitive intruder alarm

Super Sensitive Intruder Alarm Circuit Principle:

IR transmitter always emits the IR (Infrared) rays which have to be received by IR receiver. When there is an obstacle in front of IR sensor, the transmitted IR rays are reflected back to the IR receiver. The output of Op-Amp is high when IR receiver receives the reflected IR rays. This output of operational amplifier is connected to the RESET pin of 555 timer.
IR transmitter always emits the IR (Infrared) rays to which have been to be received by IR ....etc
