Need to remotely monitor Alphasense gas sensors and ISBs? Here you’ll learn the guts and details of how to quickly and easily monitor air quality with Alphasense + Tools.Valarm.net.

You’ll also find these Tools.Valarm.net calculators quite helpful for automatically calculating ppm / ppb gas measurements based on your Alphasense sensor configurations, tables, formulas, and calibrations.

Tools.Valarm.net is an open platform for remotely monitoring sensors made by any hardware manufacturer, whether you need to monitor water, air, vehicles, or anything else. Perhaps you’re monitoring levels of water / fluids, levees / dikes, flood warning systems, with sensors made by any of the following:

Or your organization needs to monitor air quality with sensors made by manufacturers like:

We’re happy to help your organization deploy your most effective remote monitoring solutions for monitoring anything, anywhere.

Now let’s get to the nitty gritty of connecting Alphasense gas sensors to Tools.Valarm.net.

 

In this here tutorial, you’ll learn how to connect Alphasense specific gas sensors to the Tools.Valarm.net Industrial IoT gateway platform.

You’ll need the following to get going with your remote air quality monitoring deployments:

First off make sure your sensor hubs are connected to Tools.Valarm.net by following the video tutorial on the How To Use Valarm Page.

To connect your 0-10V sensor adapters to your Alphasense sensors you’ll attach the wires from your Alphasense fixing kits and your 6-way Molex sockets.

  • Red wires connect to the Positive (+) of your voltage regulator that supplies 6V of power (VIN + on your Alphasense gas sensors ISB circuit boards)
  • Black wires go to the Negative (–) of your voltage regulator that supplies 6V of power (VIN – on your Alphasense gas sensors ISB circuit boards)
  • Green cables connect to Channel 1 Ground on your 0-10V sensor adapters (OP1 – on your Alphasense B4 series gas sensors ISB circuit boards)
  • Orange cables screw down in your sensor Input for Channel 1 on your 0-10V sensor adapters (OP1 + on your Alphasense gas sensors ISB circuit boards)
  • Brown cables connect to Channel 2 Ground on your 0-10V sensor adapters (OP2 – on your Alphasense B4 series gas sensors ISB circuit boards)
  • Yellow cables screw down in your sensor Input for Channel 2 on your 0-10V sensor adapters (OP2 + on your Alphasense gas sensors ISB circuit boards)

Now on Tools.Valarm.net your voltage values for channel 1 from your 0-10V sensor adapters correspond to your working electrode voltage values.

And your voltage values for channel 2 are your auxiliary electrode readings.

Use these in your formulas from Alphasense for calculating ppm (parts per million) of your gas sensor measurements of:

  • Carbon Monoxide / CO
  • Hydrogen Sulfide / H2S
  • Nitric Oxide / NO
  • Sulfur Dioxide / SO2
  • Ozone / O3
  • Nitrogen Dioxide / NO2

Also note that you’ll install Yoctopuce temperature sensors very close to the membranes of your gas sensors. You can use these temperature values for adjusting for sensor temperature sensitivity in your calculations and correction factors of your gas sensor readings. You’ll see a temperature sensor next to the NO2 and SO2 sensors in the photos on this page. In the Tools.Valarm.net Device Manager screenshot you’ll see we’ve mapped the sensor and temperature values like this:

  • Volt 1 – Nitrogen Dioxide / NO2 working electrode voltage
  • Volt 2 – Nitrogen Dioxide / NO2 auxiliary electrode voltage
  • Volt 3 – Sulfur Dioxide / SO2 working electrode voltage
  • Volt 4 – Sulfide Dioxide / SO2 auxiliary electrode voltage
  • Temp 1 – Temperature of Sensor Membranes

 

Now that your remote sensor information is connected to Tools.Valarm.net you can map, graph, analyze, and download your data.

If you don’t already have GPS sensors on your monitoring units, then you can get them at Shop.Valarm.net. Then you’ll be able to see your mobile air quality information on 2D and 3D maps like you’re seeing in the screenshots on this page.

Need to monitor Particulate Matter, Dust, PM1, PM2.5, and PM10? Have a look at this tutorial for how to add Alphasense OPC-N2 optical particle counter sensors to your air quality monitoring systems.

Or perhaps you need to monitor other gases, like CH4 / Methane, with ambient gas sensors made by Clairair?

That’s the overview tutorial for using Tools.Valarm.net to monitor air quality with Alphasense gas sensors connected to Alphasense ISBs. Your organization can use Tools.Valarm.net to monitor just about anything, anywhere. And your Industrial IoT devices connect to Valarm Tools Cloud via any internet connectivity, like 3G/4G GSM, LTE, WiFi, Ethernet, LPWAN, or RPMA like Ingenu.
