DIY Activity MonitoriNG
We built a low cost DIY portable locomotion activity monitor or pLAM for short. We used it to measure activity of moths under various artificial and natural light conditions in the lab and the field, but the device can be used for monitoring any behaviour even in limited light conditions by leveraging IR light and cameras.
