Hello,
I am using the machine uptime monitoring sensor that I got a few months ago with the magnetometer/accelerometer and I want to be able to see the time domain data bring transmitted. I found the machine uptime library/dashboard but it doesn’t have continuous data just a counter and I haven’t been able to figure out how to use the accelerometer for real-time collection as continuously as possible.
Is sending the “time domain data transmission” possible through node red? I have to think it is because the dashboard has a battery level history in the time domain and I can set the sampling rate for the accelerometer.
Any help is greatly appreciated.
Thank you.
Hello Danielle, This sensor does not provide time-domain vibration data. This device uses the accelerometer/magnetometer signal to detect when the machine is ON or OFF.
- In the case of the Accelerometer, you have the Set Accelerometer Threshold. If vibration values go above this threshold, the sensor detects this as a signal that the machine is ON. If vibration values go below this threshold, the sensor detects this as the machine is OFF. (it also calculate machine uptime in seconds).
- A similar process applies to the Magnetometer.
Since this device supports different kinds of input, the dashboard template will display the actual counters and uptime (in seconds) values, along with a battery percentage history. It is designed as a simple template to view the sensor data in an easy-to-read format. In order to get started I would recommend to test the behavior using the Node-RED editor into the Debug window.
I highly recommend taking a look at the product datasheet and user manual for more reference.

Thanks for the reply Eduardo, what sensor could I use for time domain vibration data? Ideally I would like to be able to put it on a machine and log some data of what frequency the machine idles at and what frequency it is when it is in use then when I log data, I can show what percent of time it is off vs idling vs in use.
Looking at the different sensors, I think I might be able to do it with this https://store.ncd.io/product/smart-industrial-iot-wireless-vibration-temperature-sensor/
Is that right?
Thanks for your help!
Hi Danielle, we do not offer a vibration sensor that measures and transmits the time-domain data wirelessly all the time.
The Machine Uptime Monitoring Sensor + Accelerometer/Magnetometer is a good alternative for Production Uptime and Machine Cycles. Using this probe, the sensor can continuously sense vibration and motion. Internally, when the vibration exceeds a configurable threshold, the device identifies the machine as ‘running’. It then increments a counter (machine cycle counter) and starts measuring time in seconds (machine Uptime).
The sensor transmits these values at user-defined intervals or upon a status change (machine OFF to ON or ON to OFF). In this sensor data, you get the machine uptime (in seconds), which is the total time the machine has been in use (running).
By taking the total time elapsed and subtracting the machine uptime, you can calculate the downtime.
The Vibration Temperature Sensor is focused on Predictive Maintenance, not OEE monitoring.
Could you please elaborate a bit more about your type of machine?
Note: We are going to release a new product which will be capable of detecting ON, OFF, and IDLE time.
Thank you,
Eduardo M
