HARDWARIO Non-Invasive Monitoring - Temperature Monitor

If you are worried about your machines being overheated in time, you can use this solution for that. It can monitor temperature on some surfaces that conduct heat or in fluids that can run through the machine itself.

It is non-invasive so you can deploy it almost anywhere in a short amount of time.

Visit other industrial projects with HARDWARIO IoT Kit on the projects page.

1. Build hardware

You will need the LCD Thermostat Kit and Sensor Module. It can run on batteries for around 2 years.

You can watch how to put together the Thermostat Kit down below, you will just plug the Sensor Module between the Core Module and LCD Module.

The last thing you will have to do is the encoder, you will have to do some soldering but you can look at the image to see how to do it.

!!!The red wire is connected to the 3V3 and 5V pin on the board!!!

2. Flash firmware

• Download HARDWARIO Playground,
• Flash firmware to the Core Module that was made for this project. You will find in the Playground by name: bcf-radio-lcd-as504x-absolute-encoder
• How to flash firmware is shown in the documentation.

3. Pair the Core Module

You need to pair the Core module with the Radio dongle that you are using, follow the instructions below to see how it is done.

• Connect your USB Radio Dongle to your computer.
• Open HARDWARIO Playground

• Click Start Pairing the LED on the dongle should start blinking
• Connect the device that you want to pair into your computer or insert the batteries.
• Wait for the device to appear in the table
• It should add the device with the Alias: magnetic-encoder:0

After you did all this you can unplug the device from the computer and plug in the USB to the socket. The next steps will be done on the computer, so you can leave the device and focus on the NODE-Red.

4. Import flow

Open Node-RED in the Playground or Raspberry Pi and import this flow from the Attachments in the Menu -> Import -> Clipboard.

Do not forget to hit "Deploy" in the top right corner to apply the changes.

This flow sends the temperature data into the graph so you can see how it was in time and maybe do some repairs.

5. Test your device

You will need to place the temperature meter into the liquid that you want to know the temperature of or onto some surface. It will then start to show the temperature on the LCD and send it to the graph.

Summary

You can use multiple sensors and measure the temperatures all around the machine so you always know what is in good shape and where you should consider some repairs.

You can make some adjustments to the code so it suits your needs and your machine needs.
