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 ...

This project demonstrates how to build an Intruder Alarm System using an HC-SR501 PIR sensor, Arduino Uno, a 5V relay, and a buzzer. The system detects motion using the PIR sensor and triggers the ...

Fig. 1: Author’s prototype arrangement for Wireless security system System block diagram. System block diagram of the wireless security system is shown in Fig. 2. The project uses PIR motion sensors ...

In this simple DIY Project, I will show you how to design and implement a PIR(passive infrared sensor) Sensor based Security Alarm System. I have designed this circuit using PIR motion sensor and ...

Fig. 1: Author’s prototype Fig. 2: Block diagram of motion sensor alarm Circuit and working. The circuit diagram of the motion sensor alarm is shown in Fig. 3. It consists of a PIR motion sensor (MS1) ...

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 ...

This project aims to help the public in protecting and avoiding criminal cases that are likely to occur in their neighbourhood. Such cases occur when the occupants are not at home or possibly even ...
