Arduino - PIR Sensor - Tutorialspoint

Arduino - PIR Sensor. PIR sensors allow you to sense motion. They are used to detect whether a human has moved in or out of the sensor’s range. They are commonly found in appliances and gadgets used at home or for businesses. They are often referred to as PIR, "Passive Infrared", "Pyroelectric", or "IR motion" sensors.

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 any presence. Fig: All connection and components ...

Room Light Controlled Using PIR Sensor and Arduino : 6 ...

Then we declare the relay pin as an output (signal only go from Arduino) and we declare the PIR sensor pin as input (signal only goes into Arduino). Finally, we use digitalread to get a reading from the PIR sensor which is either 0 (no motion) or 1 (motion) and store it into the variable val. Then we use an if and else statement to use this value which we stored to turn on/off the lightbulb ...
