Save Your Time + Money: Monitor Industrial IoT Sensors. Email us: Calculators – Remotely Monitoring IoT Air Quality Systems With Sensors Made By Alphasense

Do you, your teams, and your organization need to remotely monitor air quality systems?

Industrial IoT sensors make it easy for you to deploy cost-effective monitoring systems for automatically measuring air quality. gives you Calculator software features that automatically convert raw air quality sensor readings to real world values that make sense to you, like ppm / parts per million.

Whether you need to monitor specific gases like Nitrous Oxides / NOx, Ozone / O3, Hydrogen Sulfide / H2S, Sulfur Dioxide / SO2, Nitrogen Dioxide / NO2, Nitric Oxide / NO, or particulates like PM2.5, we’re here to help you deploy your most effective air quality monitoring systems.

You’ll learn in this write-up how to use calculators with Alphasense air quality sensors. Alphasense B4 series air quality sensors and ISBs report gas readings in multiple raw voltage measurements.

Your volt readings from your Alphasense air quality sensors and ISBs (Individual Sensor Boards) are uploaded to via your sensor hubs connected to your 0-10V sensors.

The gas concentration calculation algorithms for Alphasense sensors also take into account temperature sensor measurements, since temperature (hot or cold!) affects the calibration curve and final air quality sensor reports.

Fortunately you’ve got all of this already taken care of for you with You won’t have to type in complicated formulas, we do that for you automatically!

You ready to get started on Your Calculators for Alphasense air quality sensors?

First up you’ll log in to your account on and go to your Device Manager.

Click your Industrial IoT device you need to configure. This is 1 of your air quality monitoring systems with Alphasense B4 series gas sensors connected to 0-10V sensor adapters, a temperature sensor, and your sensor hub, e.g., WiFi, Ethernet, or 3G GSM mobile cellular telephone network like Ting, AT&T, or T-Mobile in the states.

Next go to Other Calculators under the orange Configure Data Path menu button.

You’ll see the Configure Misc Calculators window where you’ve got a list of types of calculators you can make. In this case you’ll want to select a calculator for air quality / gas, particularly the Alphasense concentration algorithm you need.

Choose the appropriate calculator for your specific Alphasense sensors and ISB products you’ve deployed.

Give your calculator a name that makes sense for you and others on your team and at your organization. Something like Alphasense SO2 / Sulfur Dioxide air quality sensor or whichever particular gas you’re remotely monitoring.

Click the blue + / plus button to create your new calculator.

You’ll see the Edit calculator window with a whole bunch of fields for you to fill out.

Add notes to your calculator so you’ve got a description of what you’re doing.

In the screenshot you’ll see an example with the Alphasense Gas algorithm 1 based on Alphasense document AAN 803-04-4-Electrode.pdf.

You’ll also see some screenshots of the Alphasense PDF documentation with formulas and look up tables. This Alphasense calculation algorithm is used for an Alphasense gas sensor with electronic offset and temperature offset.

You can choose the Output Channel / Field where you want the air quality sensor calculation results to be saved in your device.

The column you choose, e.g., Calc 01, will store all of your historical and real-time air quality sensor information that is the result of this algorithm calculation.

Set your Input Channels that are whereyour 0-10V sensor measurements are being saved in volts. Double check which column you have mapped to your Alphasense OP1 channel, a.k.a., working electrode voltage.

Set Input channel 1 to your Alphasense OP1 reading. Input Channel 2 is your field where you’re saving your OP2 / AUX auxiliary electrode voltage from your Alphasense sensor.

Your 3rd Input channel is your device’s field where the temperature in celsius is being measured right next to your Alphasense gas sensor. In the photos above you can see examples of temperature sensors installed right alongside the Alphasense ISBs.

You’ve also got additional ” Electronic Offset ” values supplied for your sensors by Alphasense. Type those in to the Corresponding Calculation Variables 1 and 2. Calc Variable 1 is your Working Electrode offset in millivolts. Calc Variable 2 is your Auxiliary Electrode offset in millivolts.

The 3rd and final Calculation Variable is your Working Electrode sensitivity in mV/ppb.

You’re almost done. You can configure interpolations and type in additional Lookup Table values, correction and compensation factors. Click the + button to add additional X and Y value pairs, where X is your input and Y is your correction factor out.

When you’re satisfied with your configuration, click the green save button. Now you’ll see your new output field in all of your features like tabular device details data views, graphs, 2D and 3D maps.
