Hi fellow community members,
I would like to sense when an electric gate is closed:
I already have the wired ones:
but I was looking for something less troublesome to install (no wires).
Are any of you aware of any BLE Contact sensor?
Worse comes to worst, I guess I’m gonna go with what @mark_pdx used in his remote sensor and build it myself with a Laird 654 series Bluetooth module, based on the nRF52840 (Laird PN 451-00001). (Thanks Mark for the details).
If you know something I haven’t found yet, please let me know.
