Hello - we have two small kids who still wander about a bit in the night if they wake and need a wee. Has anyone heard of a motion sensor alarm that you can just hang off, or stick to, a yurt door to wake us all up if one of them tries to nip out during the night?
I’ve done some googling but I’m really looking for the simplest, battery operated one.
Any recommendations for camping/caravanning etc?
Thanks!
