This burglar alarm system circuit is using a infrared proximity detector that triggers an alarm when the rays falling on its sensor are interrupted. It is different from others burglar alarm systems ...

By using this Circuit, we can increase the range of emitted IR radiation up to 100cm. It means we can increase the IR transmitting distance multiple times using this Long Range IR Transmitter circuit.

IR sensor is very popular sensor, which is frequently used in many applications in electronics, like it is used in Remote control system, motion detector, Product counter, Line follower Robots, Alarms ...

The working principle of this circuit is extremely simple and straight forward. When the infrared proximity sensor (E18-D80NK) senses an object in front, its internal NPN transistor pulls the output ...

This is a project circuit which helps to a person in the driving seat and gives an alarm if there is any obstacle or a wall while parking or while driving in reverse. This is a project circuit which ...

Fig. 1: Circuit diagram of fire alarm The circuit senses ambient temperature using LM35 and checks the presence of flame with an IR sensor. Yellow- or red-coloured flames emit IR radiation, which is ...

There are various applications of IR sensors such as TV remote controllers, burglar alarms and object counters. Here we have used IR sensors (infrared LEDs) to make an object-detection circuit and ...
