The objective of this project is to create a simple and effective alarm system using an ATtiny85 microcontroller, a wired door opening sensor, a relay module, a car siren, and an indicator LED. The alarm will be triggered when the door opening sensor detects the opening of a door, and it can be deactivated using a switch connected in the power line
This repository contains the code for a comprehensive security system based on IoT nodes with ESP32 microcontrollers. It consists of master and slave nodes, along with a mobile application for remote control. The system detects intrusions via motion and door sensors, activates alarms, and provides a user-friendly interface for managing security.
