Home Security System

Intelligent embedded security โ€” built from the ground up.

A fully embedded, real-time home security platform built on ARM Cortex-M. The system integrates motion detection, door/window sensors, siren control, and a remote alert mechanism โ€” all running on a custom RTOS-based firmware stack with a bootloader for secure OTA updates.

Product Features

Real-Time Motion Detection

PIR sensor integration with interrupt-driven detection and configurable sensitivity zones.

Multi-Zone Door & Window Sensing

Reed switch and magnetic sensor support across multiple zones with individual arming.

Siren & Alert Control

PWM-driven siren with configurable alarm patterns and remote GSM/SMS alert delivery.

OTA Firmware Update

Secure firmware updates via a custom bootloader with CRC validation and rollback protection.

Low-Power Operation

Deep sleep modes with timed wake-up and sensor interrupt wake paths for battery efficiency.

Status Display

OLED-based local status panel showing zone state, armed/disarmed status and event log.
