valarm-tools-cloud-industrial-iot-remote-monitoring-sensor-telemetry-industry-4-0-gaba-german-american-business-association-event-3Need to know when 1 of your Industrial IoT sensors is measuring a value significantly greater than 1 of your other sensors?

Perhaps the difference between 2 of your temperature, air quality, or any other combination of sensors is greater than, or less than, your critical threshold. You’ll need automatic alerts via e-mail and/or SMS text message when that happens. With any of your remotely monitored industrial assets deployed in the field.

The new comparators on let you compare measurements from 1 of your sensors to any other 1 of your sensors. You’ll want to use this IIoT sensor comparing feature if you’re monitoring 2 pumps, tanks, wells, air quality sensors or any other industrial assets, and you need to receive an alert that tells you 1 sensor reading is greater, or less than, another sensor. The IIoT sensors you choose to compare don’t need to be the same sensor factor. You can compare temperature, humidity, light, and any combination of sensor values.

Please don’t hesitate to Contact Us at if you need features implemented for your specific remote monitoring, IIoT, and sensor telemetry needs.

Let’s go through the tutorial steps on how to use the new comparators for multiple sensor fields. you’ll first look at the details of 1 of your Valarm devices on Then under Configure Data Path you’ll configure Outbound Alerts and Threshold Responses.

You’ll see a screen like the screenshot where you can enable an outbound alert by checking the checkbox at the top. Use the tabs up above to configure multiple alerts. Select the way you want to receive your sensor alert, e.g., E-Mails or SMS Text Messages.

Give your alert a name and choose how many alert messages you want to get sent out.

Don’t forget to enter the destination info like email addresses of the folks you need to receive the alerts.

tools-valarm-net-valarm-tools-cloud-industrial-iot-remote-monitoring-sensor-telemetry-air-quality-water-comparators-threshold-multiple-sensors-2For your input channel you can select any of your sensor fields / columns like VOCs, CO2, temperature, humidity, tank levels, flowmeter totals, water well depths, or any other sensor factors you’re monitoring.

Under the Threshold Comparator you’ll see the new options you can pick for comparing 1 sensor channel to another:

  • Greater Than (another sensor field / channel)
  • Greater Than Or Equal To (another sensor field / channel)
  • Less Than (another sensor field / channel)
  • Less Than Or Equal To (another sensor field / channel)
  • Equals Exactly (another sensor field / channel)
  • Difference Greater Than (another sensor field / channel)
  • Difference Less Than (another sensor field / channel)

tools-valarm-net-valarm-tools-cloud-industrial-iot-remote-monitoring-sensor-telemetry-air-quality-water-comparators-threshold-multiple-sensors-1Once you choose 1 of these you’ll use the the Compare to Channel option to pick the 2nd sensor you’ll be comparing to the 1st one. If you’ve selected a threshold comparator that uses a difference then will automatically subtract each sensor value reading from the other. Then if the difference is less than, or greater than, (whichever you choose!) the Threshold Value you entered, you’ll trigger an Outbound Alert, like the e-mail alert example in the screenshot here.
