A rugged three-axis vibration and temperature sensor for rotating machinery — motors, pumps, fans and gearboxes. It reports acceleration, velocity and displacement over LoRaWAN so NARA's predictive-maintenance models can flag bearing wear, imbalance and misalignment weeks before a breakdown. IP67 housing, a replaceable 8,500 mAh battery and stud or magnetic mounting make it a fit-and-forget retrofit on existing equipment.

A certified-style hard hat with built-in intelligence for high-risk sites. It detects falls, helmet removal, inactivity, high temperature and proximity to live voltage, raises an SOS on demand, and speaks voice alerts directly to the wearer. Every event is reported over LoRaWAN to the NARA safety dashboard, so supervisors see who needs help and where — without phones or extra wearables.
A wearable badge that keeps every worker visible, indoors and outdoors. It switches automatically between GPS, Wi-Fi and Bluetooth positioning and reports over LoRaWAN with a 2–5 km range. A dedicated SOS button, buzzer, RGB LED and motion sensor turn it into a lone-worker and man-down device. Up to 5,000 records are stored locally when coverage drops. ATEX version available for hazardous areas.
