TEG-Powered Smoke Monitoring System with GSM Alerts

Purpose

The forests most at risk from wildfire and illegal land clearing are exactly the places with no mains power and no internet, so the equipment that could catch a fire early has nowhere to plug in. A research team set out to prove a sensor could run on the waste heat around it and still raise an alarm from the middle of nowhere.

Description

We built a self-powered smoke-monitoring unit that harvests ambient heat, turns it into enough electricity to keep its own sensors running, and reports smoke events over the cellular network from areas that have no other coverage at all. The system continuously reads smoke and temperature levels, measures the energy it produces, and holds up under a real outdoor deployment rather than a lab bench. It's the kind of off-grid, energy-harvesting sensing problem, power and environment and long-range alerts at once, that we take on and see through to a working field prototype.
