LoRaWAN 5-Button Panel with Speaker

A wireless panel with five push buttons that turns a single press into an event in NARA. Assign each button its own meaning — service call, customer feedback, cleaning request, machine status, material shortage or help needed — in restaurants, hotels, washrooms, hospitals, retail and production lines. A built-in speaker confirms each press with an audible signal. Events are sent over LoRaWAN to NARA, where they trigger notifications, work orders or satisfaction reports. The panel runs on two standard AA batteries and needs no wiring, so it can be mounted wherever it is needed.
