Product Overview:
Communication unit (electric meter/ LoRa wireless) is a kind of IoT communication module with ultra-long distance transmission, using LoRa debugging technology, and following LoRaWAN wireless transmission protocol. It can auto-acquire electric meter address so as to build IoT network rapidly, and cooperate with LoRaWAN gateway to realize data Transmission, monitoring and smart management. At present, it is widely used in the field of electric data acquisition. The communication unit (single phase/LoRa wireless) is used in single phase electric meter and the other for three phase electric meter.
