Device Overview
Introducing NCD’s Long Range Industrial IoT wireless vibration and temperature sensor, boasting up to a 2 Mile range using a wireless mesh networking architecture. Incorporating a 16-bit Vibration and Temperature sensor, this sensor transmits highly accurate vibration data at user-defined intervals.
During Power-Up, this vibration sensor learns “normal” base-line vibration from the monitored device. This base-line vibration is subtracted from regular sampled vibration readings to improve relevant vibration data. Ideally, the monitored device should be off while the sensor is learning. Once the sensor stabilizes and starts sending data, the device/machinery being monitored can be powered on.
This Industrial IoT Wireless Vibration Sensor samples 3-axis of Vibration data and calculates RMS, Maximum, and Minimum vibration readings. This sensor combines these data with temperature data in a data packet, and transmits the result to modems and gateways within wireless range. Once transmission is complete, the vibration sensor goes back to sleep, thus minimizing power consumption.

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.
