Device Overview
1 Channel Industrial IoT Long Range Wireless Ultrasound Vibration Sensor Capabilities
The Industrial IoT Ultrasound Vibration Sensor from NCD – a high-performance solution engineered explicitly for industry-leading predictive maintenance applications. Integrated with a wireless mesh networking architecture, it delivers an impressive range of up to 2 miles. The sensor employs a high-precision, dual-channel 15-bit ADC, capturing vibration data at user-specified intervals and wirelessly transmitting the recorded data to remote modems and gateways.
Designed with a focus on energy efficiency, the sensor seamlessly transitions into an ultra-low power sleep mode between data sampling periods. Its integrated 16V buck-boost power supply negates the requirement for an external power source, enhancing its versatility.
Powering the sensor are six AA batteries that, coupled with an operational capacity of up to 100,000 wireless transmissions, afford an estimated battery lifespan of 10 years. This lifespan depends on environmental conditions and the frequency of data transmissions. The sensor also supports optional external power from a 6-18VDC supply for added flexibility.
Its superior range, high precision, extended battery life, cost-effectiveness, and fortified security features position this sensor as an exceptional tool for predictive maintenance tasks in various industrial contexts, exceeding the standards set by traditional devices.
Its main feature include:
- Industrial Grade 1-Channel Ultrasound Vibration Sensor
- Resonant frequency Fres = 37 [kHz] +/- 1 [kHz]
- Measuring range 20 to 100 [dBµVRMS]
- Resolution 0.5 [dB𝜇𝑉RMS]
- Ideal For Motors, Pumps, and Gear Box Predictive Maintenance
- 2 Mile Line-of-Sight Range with On-Board Antenna
- Superior LOS Range of up to 28 Miles with High-Gain Antennas
- Wireless Mesh Networking using DigiMesh®
- Open Communication Protocol for Easy Software Integration
- Validates and Retries Lost Communication Packets
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.

Power Requirements and Expected Battery Life
Power Requirements
This Sensor has two power options:
- Powered by AA batteries (NCD recommends Energizer L91 batteries)
- External power supply (5-18 V DC) Current Requirement 250 mA
While changing the batteries:
- Turn off the sensor
- Only use new L91 batteries
- Checkout the polarity marking on the battery holder and batteries
- Replace all six batteries with new L91 batteries. Do not mix old and new batteries
- Batteries should not be replaced in fire-risky areas
- Do NOT install rechargeable batteries
