Circuit diagram of pir sensor

This automatic staircase light circuit switch on the staircase lights automatically when someone enters on the stairs and gets off after some time. Our bodies generate infrared heat . PIR stands for Passive InfraRed. This electronic security system can be used in banks and other high security areas. The transmitter sends out an IR laser and this will be .

Working of the circuit is simple and straight forward .

A Simple Understanding of how transistor works. See more ideas about Circuit diagram , Arduino and Electronic circuit. This is one basic electronic circuit to get started with electronics. There are some motion detectors which will use different technology and include number of sensors ( PIR , microwave sensor , ultrasonic sensor , etc.) to reduce the false triggering and . Motion detector can be used as intruder.

The main electronic component we will use that allows us to pick up this detection is the PIR motion sensor. Below is the schematic diagram of the motion detector circuit : . PIR Sensor based Security Alarm Circuit Diagram. To detect movement or motion of person the simple PIR (Passive InfraRed) circuit can be use it gives reliable output than simple photocell or photo diode circuits. So that the IR energy on the sensor will not trigger the alarm.

This prevents false triggering when exposed to flashes of light. The differential amplifier also minimizes the common mode interference from electric fields. This circuit diagram constructed by using simple and easily available components.

The circuit diagram of the motion detector using NE5timer is shown in Fig. The SPDT ( Single Pole Double Throw) Relay coil is connected between Vcc and Q1 . Find and save ideas about Light sensor circuit on Pinterest. Burglar alarm system is an important part of home security systems.

Circuit connections are shown in the above circuit diagram. Here the circuit constructed for to detect the movement and gives beep sound. You can modify the circuit with relay or bulb.
