Multiple Temperature Sensors

Hardware

Does NCD make a sensor that has multiple temperature probes?

I’m looking for a 4 sensor unit instead of buying 4 single units. Even a 2 sensor unit could work.

It’s for freezers, so just temp.

Cheers,

What is the Node-Red sensor type for this sensor.

I see one called RTD Temperature Sensor , but I don’t see a 2 channel version.

Hi Todd, the Node-RED sensor type you should use is 54. It is possible you will need to update the NCD Library; to do this, follow these steps:

  1. Go to the Node-RED main menu (three horizontal lines at the top right side).
  2. Click on ‘Manage Palette’.
  3. Locate the library @ncd-io/node-red-enterprise-sensors and click on the ‘Update’ button. (You require an internet connection to perform the update).
  4. Finally, you will need to confirm and restart your Node-RED instance. If you are using the Enterprise IIoT Gateway, you can use a simple flow to restart Node-RED:
  • Download this flow:
    restart_nodered_flow.json (1.8 KB)
  • Go to the Node-RED main menu and click on the ‘Import’ button.
  • Click on the ‘select a file to import’ button and select the JSON file.
  • Click the ‘Import’ button.
  • Go to the new ‘RESTART’ tab and enable the flow to restart Node-RED.
  • Refresh the web page (it might take a few minutes, please be patient).

After completing these steps, you should be able to see the 2-Channel Device in the sensor type dropdown menu.
