In our home we have various types of electrical home appliances like a refrigerator, air conditioner, cooler, water purifier, water pumping motor, grinder, mixer, etc. These devices have internal motors to pump or suck air and water; when they are not able to do this function, the motors cause noise and it will be irritating and can cause sound pollution. Because it is dangerous to use these devices perpetually, there is a need to undergo maintenance. In order to claim the warranty, we can send a report to the firm to replace or undergo maintenance. The detail report on the device health can be preferable for warranty claim purposes for this we need a SensorTile-like device. Through this device we can measure the system acceleration, noise, vibrations and can complete the report. It will be a bit difficult to understand the issue with our device for the technician when we interact with them in a telephone call. So they need to come first, check and again come with required material to undergo maintenance. In this process, there will be breaks to understand the system health and why water is an important source to us.
Explained in the following steps is how to send a detailed data report to the authorized service center using a SensorTile device about the water purifier health status to undergo maintenance or replace it.Step 1:
When the purifier was in good working condition it was not making any noise or vibrations. Sometime later there was a problem with the water purifier in my home, it was making a vibrating noise and purified water was not able to fill the tank.
SensorTile is placed on the water purifier to record the vibrations and noise levels.
Open the ST BlueMS Android Mobile app to record the data and start searching to identify the device.
Be sure to switch ON the SensorTile and Bluetooth on your mobile phone, then the app identifies your device as listed. Click on the device to interface connection.
Once the connection is established, the app screen appears like in the below figure. Click on START LOGGING to log data of the parameters like temperature, humidity, pressure, accelerations, direction, position, noise from the on-board sensors. Swipe the screen to see the recording data on the mobile screen.
This how the sensorTile looks when it is designed from PCB designing software.
The measurement can be viewed on the screen plotting accelerations which shows the system is making vibrations when it is running. It may indicate a small oscillation in the graph but for this small system these levels are more.
We can go the noise level by selecting MIC option in the app. As soon as we switch ON the water purifier the noise level is increasing instantly which indicates that the system is not in good condition and the intensity level is dangerous to the human ear. The below figure shows the increase of sound when it was switch ON.
As soon as the system is switched OFF the noise level is going drop which indicates that the system was not for use and it is also not pumping water to the tank.
An analysis is carried out and the graphs are plotted from the recorded data. The analysis graph shows the confirmation on the system health from on-board Accelerometer and Gyro. Both the sensors indicate the high vibration levels. The linear line in between indicates it was turned OFF.
The recorded data can be sent through email to the authorized service center after performing the health check.
The video shows how we had carried out the instrument health check using the SensorTile device.Conclusion:
SensorTile device is suitable to monitor and check the electrical system in our home due to its on-board features. Using this we can check any system's health conditions and can send data to the authorized service center to undergo maintenance or replacement during the warranty period. It helps the technician to understand the fault of the device, so they can come with proper materials to sort out the repairs in advance. Water is an important resource for humans, so the problem should be rectified as soon as possible. This is how this SensorTile plays an important role in our home to check the systems health status.
