I need some advise on which configuration I should use to get my project working.
What do I want to do: register the activity in nesting boxes for owls.
These boxes are at remote places so I need a battery operated system. I devised an arrangement with two micro switches (and one with two reed switches) that register an owl getting in or out of the box. Currently I am using a LoPy unit but that device cannot keep track of time in deepsleep mode. I need this functionality to keep track on how long an owl is inside the box.
So I am looking for another configuration that can provide the following functionality:
- Two digital inputs for the switches
- Keep track of elapsed time in between the activation of the switches while in deep-sleep mode.
- A “powerful” LoRa unit. As the boxes are at remote area I need a lot of range.
- As we inspect the boxes at least once a year a battery life of 2 years should be good enough.
Any advise is appreciated!
