All Hail the Battery Monster

John came round to see me today. He’s been working on hardware for our environmental sensor. We’re hoping to put a few of these around the village to get a feel for particle counts and how they change over time. The aim has been to create something that can be left on a building for as long as possible and just work.

My experience with making these devices is that power is often your biggest problem. Our lamppost sensors have it easy because they can use a local power supply. But our devices are going to be self contained by the cunning use of sleeping software and the biggest batteries we can find. John has put together the above. It should run for a few months or more.

With a bit of luck we should have them out and about soon.
