What’s Your air quality right now?

Not in your city or neighborhood, but exactly where you are! If you don’t know, and you want to know – you can have a cost-effective, mobile solution with Valarm.

UPDATE: We highly recommend you use more reliable and robust Valarm sensor connector devices (e.g., WiFi, ethernet, or GSM sensor hubs), an RS-232 sensor adapter, along with Dylos air quality sensors for monitoring air quality + particulate matter in real-time, including:

  • PM0.5
  • PM2.5
  • PM10
  • Dust
  • Pollen


Do you know about the Alphasense OPC-N2 Particulate Matter sensor?

The OPC-N2 is an Optical Particle Counter that is highly accurate and monitors PM1, PM2.5, and PM10. Have a look at how SC-AQMD, the government agency responsible for air quality monitoring and compliance in Southern California, uses the Alphasense OPC-N2 and Valarm to monitor air quality.

When you combine and your Sensor Hubs with the Dylos DC1100 Pro Air Quality Sensor or DC1700 – you get affordable, geotagged air quality information.

You can use to decide what activities you should or shouldn’t do right now and any dust cleaning that may need to be done. supports a wide variety of sensors you can combine with your air quality info such as temperature, humidity, VOCs / Volatile Organic Compounds, and Carbon Dioxide / CO2.

Your sensor data is geo-tagged meaning all of your Valarm data has latitude and longitude coordinates so you can easily see air quality on a web-based Industrial IoT dashboard or map like the one below.

You can also graph any of your Valarm sensor data in real-time and forward your data anywhere using our APIs for JSON, GeoRSS, KML, and CSV. The air quality graph below shows the particulate matter changes over time. It’s the same air quality data collected from Los Angeles, California, as shown in the map above, just this time it’s shown in a graph format on Valarm Tools Cloud /
