Explore the 3 Channel Industrial IoT Wireless AC Current Monitor Sensor Capabilities
Device Overview
Introducing NCD’s Long Range Industrial IoT Wireless 3 Channel AC Current Sensor, boasting up to a 2 Mile range using a wireless mesh networking architecture. This 3 Channel Industrial IoT Wireless AC Current Monitor Sensor transmitter works together with three split core current sensors (included). It samples current at a high data rate and calculates the RMS Current value and sends a wireless transmission. This process is repeated at user defined timing interval while sleeping in between to minimize power consumption. The sensor comes with three 1.25 meter long split core current sensors which makes installation easy.
This 3 Channel Industrial IoT Wireless AC Current Monitor Sensor is capable of detecting change in current at user defined detection time intervals and sending out data if the current change is greater than user defined detection change percentage. This change detection feature can be enabled or disabled as needed. To minimize power consumption, the current sensor sleeps to preserve battery life. Both of these features work together to support multiple application areas in one package.

Status LED
The Status LED is used to indicate errors or other sensor diagnostics.
LED blinks once – Message was sent successfully and no error in last sensor read as well in data transmission.
LED blinks twice and then one more time – Message was sent successfully but there was an error in last sensor read.
LED blinks thrice – MCU is having issue communicating with the radio module.
