· Circuit Components. PIR Sensor (we used HC-SR501) Resistor 220ohm (any resistor below 1k ohm) LED; Battery (5-9V) Circuit Diagram and Explanation. PIRs takes some time to stable itself according to surrounding conditions, so you can find, LED turn ON and OFF randomly for about 10-60 seconds. Now when we find the LED blinking whenever there is any motion, look back of the PIR, …
This circuit constructed by one PIR sensor, a switching transistor SL 100, one Relay switch and indication led, when the sensor detects the motion towards the sensor surface then it enable current flow through the switching transistor, then the relay automatically turned ON.

This circuit constructed by one PIR sensor, a switching transistor SL 100, one Relay switch and indication led, when the sensor detects the motion towards the sensor surface then it enable current flow through the switching transistor, then the relay automatically turned ON. (we can connect buzzer or alarm device in relay or instead of relay to create motion detector alarm). The LED indicates ...
· When the PIR sensor detects any motion the relay is turned on, so the common pin of the relay will be connected with the normally open pin, which connects 5 volts with the anode side of the LEDs, and so the led’s will turned On. The relay driver circuit simply consists of the 2n2222 NPN transistor and a 10k resistor.
· Following is an ordinary circuit that activates a relay when a living being (a human) is detected by the PIR sensor. Here PIR symbolizes Passive Infrared sensor. …
Circuit diagram of the PIR Motion Sensor Light and Switch based on SB0061 shown here can be used for security or corridor lighting in power saving mode. The 12V DC supply required for the whole circuit can be fed from any standard 12V ac mains adaptor/battery. Working of the circuit is simple and straight forward. When any movement is detected within near 5-6 metres, around Volt is ...
· Automatic Room Lights using PIR Sensor and Relay 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.
· hi ken thanks for your reply, i am using a PIR sensor BS1600( PIR Sensor Module), 12v 5pin relay. i am getting at the output or PIR sensor and with this i want to trip the relay to which i am giving 12v supply. as i want to use 12v from relay weneva any motion is detected by a sensor so i need suggestions regarding the connection and wiring of sensor with 5pin 12v relay. the circuit is ...
Because, I was still waiting for the WS2812B boards that time and remembered and asked my self "Hey! I have a couple of PIR motion sensors in my Arduino Arsenal. Now, what can I do with it?". So, I came up with this one. I guess that's it. Just watch the video if you want to know more. Thanks! Here are some helpful Images and links on how to connect and setup things. PIR Motion Calibration ...
· For The S1-switch on-off the relay circuit. When you want to close a siren. Also, you can use a remote control instead of S1. When PIR Sensor runs, it will give a very short signal. We need to keep this voltage with a capacitor. And Diode-D1 protects a discharge voltage of C1, not reverse to PIR sensor.
Note: – PIR sensor only detect the presence of the infrared rays which comes into its range, it does not emit infrared. Related Post: Simple Touch Sensitive Switch Circuit using 555 Timer & BC547 Transistor Working of Motion Detector Circuit. The PIR sensor typically operates at 5V, so we are using a positive voltage regulator IC 7805, which will give 5V output to feed the sensor.
· The design is based on a PIR motion sensor circuit which can be easily built using the following basic set up and applied as a burglar alarm circuit. Here we can see, the system can be assembled using just 5 fundamental components, which are: 1) The PIR Module 2) A 1 k resistor, 3) An NPN transistor, 4) A Relay, 5) An Alarm Siren unit.
· Relay Output :Common(C),Normally Closed(N/C),Normally Opened(N/O) Relay ON time: 15 Secs (Not Adjustable) Pir motion sensor unit. At this moment set up the PIR module suspending from a 3 metre high mast (to insure 10 metre radius area) and hook up its supply and relay pins to your completed and encased circuit, paying attention to right ...

A Simpler Explanation for Everybody : Here PIR, When senses Motion,Outputs - - so we would be using this output pin to turn on and off the transistor which is on board. In Return Transistor Will complete the Circuit and Relay will also turn on and off with transistor. I …
PIR sensor consists of three pins, ground, signal, and power at the side or bottom. Generally, the PIR sensor power is up to 5V, but, the large size PIR modules operate a relay instead of direct output. It is very simple and easy to interface the sensor with a microcontroller. The output of the PIR is (usually digital output) either low or high.
Here PIR, When senses Motion ,Outputs - - so we would be using this output pin to turn on and off the transistor which is on board. In Return Transistor Will complete the Circuit and Relay will also turn on and off with transistor. I Hope this can't be more …
· B1. It is a Low level relay (1) The relay module seems to have only one transistor, and that it all. For one transistor circuit, there are two possibilities, (a) PNP BJT based level trigger, (b) NPN based High level trigger. The product sheet says it is Low triggerable, so that is it, no more and no less.
· How to properly connect a Relay Module to turn on a light or other device when we detect motion. This is simple but good to know when playing with High Volt...
· Circuit Diagram and Explanation: The circuit Diagram for arduino motion detector project by interfacing Arduino with PIR module and blinking an LED/Buzzer is shown in the below image. We have powered the PIR sensor using he 5V Rail of the Arduino. The output pin of the PIR Sensor is connected to the 2 nd digital pin of Arduino. This pin will be the INPUT pin for Arduino.
