Brilliant! Could be very useful for humane pest control too. Although I hate the mess and damage house mice make.
It would be very useful to do this type of project with humane traps for ecological monitoring.
We used these traps in the 80's Longworth Small Mammal Trap | NHBS Wildlife Survey & Monitoring to monitor populations of wood and yellow-necked mice in the Midlands UK.
It would be great to bring this type of work into the 21st century.
So when a trap becomes occupied you are alerted and can go to investigate / identify the critter. Or better still, with web cams in each trap, you could ID the critter remotely and then release it automatically via your link. How about biometric sensors for length and weight etc...= total armchair ecology
