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

Most NCD IoT Sensors are rated for 100,000 to 500,000 transmissions until the batteries become so weak they are unreliable. You could spread these transmissions out over a 10 year period and send 50,000 transmissions per year. This would allow up to 136 transmissions per day, or about 5 transmissions per hour (for a 500K sensor, or 3 per hour for 300K sensor). If you only need the batteries to last 3 years, you could send 166,666 transmissions per year, or about 456 transmissions per day (about 19 transmissions per hour for a 500K sensor). As you can see, battery life is really up to you. By altering advanced settings in the NCD IoT sensor, you have control over longevity. Please note the 500,000 transmission rating is for premium alkaline batteries. NCD ships all sensors with premium Lithium batteries, which include a ultra-wide temperature range that typically lasts in excess of 600,000 transmissions for some sensor types. These batteries weigh less than half of alkalines, and they work in the freezer! A word of caution though, putting a sensor in configuration mode will drain the batteries very quickly. It’s important to configure your sensors and exit configuration mode as soon as possible or use a external power supply during configuration (if supported by the sensor). The table above indicates how many Transmissions Per Day (TPD) your can expect from different sensors over a lifespan of up to 10 years.
