In Industrial IoT (IIoT) and Smart City applications, reliable, long-range monitoring of switch states or pulse signals—such as water meter pulses, equipment status, or door alarms—is critical. Especially in remote areas lacking power or facing harsh environmental conditions, traditional wired solutions are often costly and difficult to deploy. The Manthink KS32 LoRaWAN Dry Contact Pulse Counter is designed to solve this exact problem, combining the long-range, low-power features of LoRaWAN with powerful multi-channel acquisition capabilities.
