I have a product that is mounted in the ground. It is using sensors which need to be calibrated after put into the ground. It uses LoRaWAN to communicate. It is very low power device. The case is fully sealed (IP rating).
My concern is after it gets assembled, I don't want to turn it on, because it will stay in stock for a while which will drain the battery, so the solution is to turn it on just before it gets mounted.
Because the case is sealed, what are the methods to turn on the device?
What are the easiest methods to solve something like this?
Thanks!
