Arduino engineer to build project

Need to sense vibration and sound impulse, once sensed the board must send trigger via lorawan to central location (up to 100 remote devices required)

Lora bridge (central device) must talk BLE bluetooth to mobile device and alp

I need the person to recommend hardware (arduino, sensors, lora radio) to use. Packaged as small and rugged as possible. Remote sensors to be powered by small solar (only functions in the day)

Impulses sent to a central location (controller) which translates to signal to bluetooth for display on mobile device - white dot, which turns yellow if only sound is detected, or green when sound and vibration is detected.

Remote devices should each have a unique id, so it can be identified from the mobile device.

W

Customers will buy remote sensors over time, so it should be easy to add devices to the lora network either via qr code, or similar method (eg, customer buys extra sensor, scans qr code and lora network onboards device)
