LoRaWAN Call Button with Speaker and T&H Sensor

A wireless push button for calling assistance or raising an alert — on production lines, at workstations, in warehouses, meeting rooms, washrooms and reception desks. One press sends a LoRaWAN message to NARA, which routes it to the right team, and the built-in speaker gives audible confirmation to the person who pressed it. A built-in temperature and humidity sensor reports room conditions between presses. It runs on two standard AAA batteries, mounts anywhere without wiring, and is available in different colours so buttons can be colour-coded by purpose.
