Portal alarm box unit, my main project on technical college.

Details

My classmate and I made this as our master project when graduating technical college back in 2010. It is a portable and modular alarm system — intended for construction sites and new buildings. Theft from construction sites is a problem that can be costly, economical and time-wise.

This system uses mobile broadband for sending notifications and alerts via e-mail and CCTV footage. It contains IR movement, smoke and temperature sensors, but is designed to be flexible with regards to sensor input and configuration.

Everything is controlled with a laptop inside the case, sensor data is interfaced from a serial I/O module.

Components

  • Smoke sensor
  • 2xIR sensors
