You’ve got a new calculator on

Valarm Tools Cloud software support for Wet Bulb Temperature was recently requested by one of our Industrial IoT customers.

We’ve finished up adding this new software feature. In this article we’ll give you a HowTo step-by-step tutorial on how to calculate Wet Bulb for your IoT sensor devices.

What is wet bulb temperature? Wet bulb temperature tells you how easy it is for water to evaporate according to this post. If you’re looking for more nerdy details on wet bulb, dry bulb, and dew point have a look at this page or on Wikipedia. We implemented the NOAA wet bulb formula and it’s been programmed into our standard Calculators list.

Note that in order to use the wet bulb calculator, you’ll need sensors for temperature, humidity, and pressure, i.e., these meteos / micro-climate weather station sensors connected to your sensor hubs.

Let’s go over how you, your teams, and your organization can use your new software feature.

To get started, log in to your account on and go to your Device Manager.

Click the name of your IoT device that you’d like to configure with a Wet Bulb Calculator.

On your device details page you’ll mouse over the orange Configure Data Path button, then click Calculators from your drop down list.

Now you’re on your make a new Calculator window. Write a name for your wet bulb calculator and select Wet Bulb in the drop down list. Then click the + to create your new calculator.

You’ll now see your Edit Calculator window for configuring your calculator. Type in notes and a description for your calculator so that you and your teams and anyone else at your organization can remember why you made this calculator.

Select an Output Channel where you’d like your Wet Bulb calculations to be written and saved. In the screenshot examples you see that we’re saving our wet bulb values to the Calculated 1 field / column, which we’ll later rename with a custom nickname / alias.

We’ve integrated the NOAA (the U.S. Department of Commerce’s National Oceanic and Atmospheric Administration) Wet Bulb formula, which requires 3 input variables:

  • Temperature
  • Humidity
  • Pressure

Select the 3 channels that correspond to these measurements. If you’re monitoring meteo sensors from, then you’ll likely choose the same sensor field options as you see in the demo screenshot – Ambient Temperature, Relative Humidity, and Barometer.

Click Save when you’re satisfied with your settings.

You’ll now see your Wet bulb calculations in the output field you chose in your configuration.

In the demo screenshots you’ll notice that we renamed the Calc 1 column to “Wet Bulb” by using these field renaming features.

Your new wet bulb calculator now creates a new wet bulb value for every piece of sensor data your sensor hubs upload to Valarm Tools Cloud.

You can use your wet bulb measurements with all of your other existing features like e-mail alerts, dashboards, 2D and 3D maps.

That’s your startup guide for getting you going on your Wet Bulb calculators. Keep an eye on our blog, customer stories, docs, and other parts of our page for additional info about your favorite remote monitoring systems.
