Gemtek has been instrumental in the development of LPWAN system solutions, and is an early provider of LoRaWAN protocol-based, end-to-end LPWAN solutions. The LoRaWAN technology is designed to connect low-cost, battery-operated sensors over long distances in harsh environments that were previously too challenging or cost-prohibitive to connect. Because of its long range, high penetration and high sensitivity capabilities, it is a much more cost effective way for service providers to deploy LoRaWAN network for sensor applications in vertical market domain.
This Manhole Sensor is designed to provide tampering monitoring of man-hole covers. Man-hole covers have a lot of theft issues; both for the coverís metal content and the valuable assets down below like fiber cables, etc. This sensor detects if the man-hole cover is being tilted or lifted and will send out alerts to the operation center. Prior to operation, the sensor is activated via magnet so to preserve battery during transport and storage. Battery is designed for more than 3 years operation based on nominal usages.
