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.

Product Features:

• Power cut event report function can be selected.
• Wide coverage of transmission.
• Suporting LoRaWAN protocol with security, high efficiency and low cost.
• Using LoRa SPSP modulation mode with strong interference immunity and not easy to disturb other equipment. 
• Ultra-high receiving sensitivity, up to -146dBm.
• Low power consumption design, energy conservation and environment protection, overall power consumption ≤0.5W.
• The adaptive serial interface speed has good compatibility.
• Supporting DL/T 645-2007 Multifunctional Electric Meter Communication Protocol.
• Supporting CJ/T188-2004 Household Metering Devices Data Transmission Technical Conditions.
