MOI Smart City & IoT Products

Air Pollution Solutions for Community Network Integration






“Smart Cities” are the future of civilization.  Could you imagine what the world would look like if every city on the planet were able to incorporate the quality of life of a “Smart City?”



Smart Cities use the latest technological advancements to make educated decisions about managing their communities’ safety and well-being, especially when it comes to all types of pollution. For this reason, MOI is at the forefront of assisting Smart Cities with their mission of air quality inporvements with precise monitoring instruments for particulate concentration and composition, and localized surface weather data.






Urban air quality is a major challenge for cities of all sizes as air quality affects us all: young and elderly, whether indoors or outside. The need for more AQ data is a key objective for decision-makers within government, healthcare, schools and universities, industry, and civic/community organizations to enable effective assessment, base policy decisions, and to initiate intervention responses.



The AQ data should be high quality, reliable, Reference or Near-Reference grade (NSIM), and readily accessible. Localized, real-time air quality data is of tremendous interest and value to the public.



Met One Instruments, Inc. offers a family of packaged, component, and OEM solutions tailored for Smart City Air Quality Monitoring that provide:


  • Reference & Near-Reference (NSIM) Grade Data Quality
  • Easy Integration to Existing Urban Infrastructure
  • Low-Cost Implementation
  • Quick Deployment with Automated Functionality
  • Accessible Data on Any Smart Device
  • Highly Portable, Mobile, or Fixed Installation
