IoT project using thermal sensors to monitor spaces

Homebrew project to monitor shared spaces using an infrared thermal imaging sensor and S2.

The S2 API will allow us to model our raw sensor output as a Stream, which is just an unbounded sequence of records – in other words, our data in motion! I added an extra field to the records (see the small bar at the top of the thermal image) to determine whether someone is really in the frame or not by doing some naïve connected-component labeling to notify me in a text message. A sweet spot temperature threshold was 28-29°C, and positioning the sensor at a height around 7-8 feet in a cooler area tends to work quite accurately!
