Motion sensor circuit

Complete information about Motion Detector Circuit Diagram and Applications. Motion detector can be used as intruder alarm in home, offices, banks, etc. This automatic staircase light circuit switch on the staircase lights automatically when someone enters on the stairs and gets off after some time.

There are two important components in this circuit , first is PIR Sensor (Passive Infrared Sensor ) and second is Relay. PIR sensor is used here to detect the Human body .

The circuit can be modified for various applications including AC operated alarm systems.

It can also turn on lights when someone approaches the area where it is .

You must connect the power, groun and sensor output to your board. Infrared (IR) Motion Detector Circuit with motion detector alarm and infrared sensor. The motion sensor circuit diagram and working is given in detail. A Simple Circuit , Controlled by two major Things.

This Can be Done on Perfboard too. Output Pin Become from LOW to HIGH which result in 3. Once motion is detected with this circuit, the LED in the circuit. This is an Arduino Project that deals with the integration of Motion Sensor with Arduino. If you do not add the LDR to the empty area of the . Or make your own PCB using the schematic given below. To find the pinout for the PIR motion sensor , look at the picture at the top of the page or check for markings . I have used old charger and tied the AC and DC cables separately.

I used Connectors for AC input and AC output for easly installation. This is motion sensor relay circuit by Sharoj Al Hasan. This is very easy circuit Anyone can make this circuit. This circuit for the Basic to advance level p. The PIR Motion Detector Circuit : For this project, we will be using our PIR motion detector module.

You need to follow the above video, which shows you how to hook it up, and how to calibrate sensitivity. 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 etc. We have already covered complete working of IR sensor here in this article: IR Sensor Module Circuit.

The buzzer stays on until the power is disconnected.
