I went to the shopping mall to buy some glue… and came back with a pir home [alarmsystem](https://www.bigbazar.eu/pagina/home) with 2 remote controls for 8 euro 😋

there’s not alot of room inside, but he the thing [works](https://www.youtube.com/watch?v=0fXnUl1GB4Y&feature=youtu.be) for the price of an empty enclosure.  
interesting is that it uses the same chip _BS00001_ as all the other china PIR’s  
If you take out the electronics there is room for your own pir loralarm … thing is not waterproof  
maybe a[TINY LoRa](https://www.thethingsnetwork.org/labs/story/tinylora-atmospheric-sensor) inside so you can still make use of the remotes leaving the original pcb ?
