4-Channel LoRaWAN Current Sensor Converter for Machine Monitoring

A LoRaWAN converter that reads up to four clamp-on current transformers (CTs) to show whether machines are running, idle or overloaded. It supports 100 A/50 mA, 300 A/50 mA and 600 A/50 mA CTs and fits onto existing motor, pump and compressor cables without rewiring — a simple way to retrofit older equipment. NARA builds running-hour, utilisation and power consumption trends from the data and triggers current alarms. The 8,500 mAh battery gives long service, and the node is configured over Bluetooth or LoRaWAN with wireless OTA firmware updates.
