21. IntroductionThe R718NL1 series is a Wireless Light Sensor and 1-Phase Current Meter device for Netvox ClassA type devices based on theLoRaWAN open protocol and is compatible with the LoRaWAN protocol.R718NL1 series have different measurement range for different variety of CT.It is divided into:R718NL1 Wireless Light Sensor and 1-Phase Current Meter with 1 x 30A Solid Core CT (Range:100mA-30A ±1%)R718NL13 Wireless Light Sensor and 1-Phase Current Meter with 1 x 30A Clamp-On CT (Range:100mA-30A ±1%)R718NL17 Wireless Light Sensor and 1-Phase Current Meter with 1 x 75A Clamp-On CT (Range:100mA-75A ±1%)R718NL115 Wireless Light Sensor and 1-Phase Current Meter with 1 x 150A Clamp-On CT (Range:1A-150A ±1%)R718NL125 Wireless Light Sensor and 1-Phase Current Meter with 1 x 250A Clamp-On CT (Range:1A-250A ±1%)R718NL163 Wireless Light Sensor and 1-Phase Current Meter with 1 x630A Clamp-On CT (Range:5A-630A ±1%)*The current is lower than the current measurement range, it will report 0 ALoRa Wireless Technology:LoRa is a wireless communication technology famous for its long-distance transmission and low power consumption. Comparedwith other communication methods, LoRa spread spectrum modulation technique greatly extend the communication distance. Itcan be widely used in any use case that requires long-distance and low-data wireless communications. For example, automaticmeter reading, building automation equipment, wireless security systems, industrial monitoring. It has features like small size,low power consumption, long transmission distance, strong anti-interference ability and so on.LoRaWAN:LoRaWAN uses LoRa technology to define end-to-end standard specifications to ensure interoperability between devices andgateways from different manufacturers.
