The PIR sensor will sense any motion in the range of 6 meters and if the motion is detected, it will send a signal to the microcontroller. Arduino will then use a GSM module to first send an SMS to ...

Working of Dog Barking Security using Arduino. Make the connections as per the circuit diagram and upload the code to Arduino Nano. When powered, the PIR sensor detects the IR rays emitted from the ...

PIR Sensor Module Parts. The topmost part of the PIR sensor consists of a lens with concentric grooves carved into the plastic. These are called Fresnel lens.. The contours on this plastic helps in ...

Fig. 1: Circuit diagram of the Arduino based GSM home automation system. Brain of the circuit is Arduino Uno MCU board (Board 1). PIR sensors (connected across CON4 through CON8) detect motion, and ...

Intruder Alert System- Developed a cost-effective security system using Arduino Uno, PIR sensors, and a GSM module to detect unauthorized entry and send real-time SMS alerts. The system features ...
