Part No.

SEN460

LoRa 1 Channel CT Sensor 60A 868MHz

Wireless single-phase current detector is used to detect single-phase electrical input current.

The device is compatible with the LoRaWAN protocol and integrates a chip module that conforms to the LoRaWAN wireless protocol to display the collected data in the gateway.

The device is powered by a battery and obtains the load AC current value through the current transformer. The device adopts the split-core current transformer, which can be conveniently connected to the measuring device.


Application

  • Indoor current detecting devices for homes, hotels, office buildings, shopping malls, etc.
  • Smart city
