Here is an ultra simple Arduino Night Alarm project wired around a handful of inexpensive and easily available components. One advantage of using Arduino as a security system is the flexibility!

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 ...

This project is an Home Alarm System made with Arduino Nano 33 IOT. The sensor used for the project is a simple PIR sensor that is activated if the correct password is typed on the keypad. If the PIR ...

There’s a huge market for 433 MHz alarm system hardware out there, from PIR motion detectors to door and window sensors. If you want to put them to work, all you need is a receiver, a network ...

This PIR sensor based security system is designed using UM3561 IC. The proposed system mainly consists of PIR sensor, UM3561 IC, Speaker, transistors. The UM3516 IC is a Siren generator IC. Circuit ...

In this paper, the Arduino based Intruder Detection System employing Rochelle Salt and Pyro-electric or Passive infrared (PIR) Sensor has been proposed. The proposed system employs Rochelle salt based ...

In India, nearly 20 percent of the electricity is lost due to technical and commercial reasons. Three billion units of power are wasted every year. The Automation of lighting system with the usage of ...

This shield includes connections to an alarm system, a GSM modem, temperature and humidity sensors, an Ethernet module, and IR movement sensors. This Arduino Mega attaches to a control box mounted ...
