Intruder Presence Detector - IPD - Arduino Project Hub

The project aims to construct a small prototype of how PIR sensor integrated with Arduino, can help to build a security system for home environment. The motive was to know if there is any intruder at the main gate of the house. With the relay system, an AC 220v alarm system can also be integrated which can make tone/noise if the sensor detects ...

PIR sensors to trigger seperate switches on relay module ...

Apr 14, 2021· The code seems to be working fine with one PIR sensor, however I have tried altering the code to accommodate for two PIR sensors (See code at bottom of post) but it would appear that when the arduino receives a signal from both sensors the relay switch flicks on and off for a period of about 5seconds before settling back down again.

PIR sensor HC-SR501 Arduino code and circuit

Oct 31, 2020· PIR sensor HC-SR501 Arduino code and circuit. A passive infrared sensor is a device which detects the infrared rays emitting from humans, animals, or similar thermal ray source. An HC-SR501 sensor is a motion detector sensor that detects the motion of the infrared emitting sources, so if the thermal body doesn’t move, then the sensor doesn ...

trigger a project with PIR sensor/timer ... - Arduino Forum

May 05, 2021· Hi, I’m fairly new here. I made a project with a 4-relay shield, operating 3 DC motors and I got that working. I even worked out how to run the program only once. I did this because I want to make it run once (or max 4 times) when a Passive Infra Red sensor with timer has been triggered. When someone passes by, butterflies will flutter about… How can I connect the 3 pins of the PIR/Timer ...
