Whenever we want cheaper sensors, say for mass-distribution, we tend to think in high-tech solutions. However, for some applications we need to return to the basics. To detect wildfires early, distributing low-cost thermal sensors presents itself as a solution. We aim to design a cheap and easy to fabricate thermal sensor that can send a distress signal when a heat threshold is reached. For this application, power consumption must be minimized. A possible design would be an iron rod that expands when it heats up, closing a circuit that is attached to a small battery. We would also love to explore potential design ideas that don’t even need a battery.
Our aim at CalHacks is to: Design a cheap and simple sensor that uses heat from the environment to power or start a signal. Do a feasibility study in which we research whether this idea is technically and economically feasible, as well as check whether distribution would be possible. Find other applications for such a “home-made” thermal sensor
We were inspired for this project by: Emily Johnston’s PhD thesis (Back-to-the-basics sensors but for mosquito tracking) And Near-Zero Power Integrated Microsystems for the IoT research by professor Matteo Rinaldi, Northeastern University
