How IoT Sensors Are Monitoring Air Quality Inside Schools

Episode 35 dives into the quiet revolution in school air quality monitoring. Lucas and Luna explore how low-cost IoT sensors are being deployed in classrooms to track CO2, PM2.5, and VOCs in real time. They focus on a case study from Baltimore City Public Schools, which installed over 2,000 sensors across 120 buildings starting in 2024. The discussion covers why CO2 levels often spike to 2,000 ppm during third period, how real-time alerts reduced absenteeism by 12 percent in pilot schools, and the surprising partnership with a local HVAC startup that retrofitted old units with IoT controls. They also touch on privacy concerns—no cameras, no microphones, just particulate and gas sensors—and the looming EPA guidelines that could make indoor air monitoring standard by 2028. A concrete look at how connected devices are changing the places where kids spend six hours a day. #IoT #AirQuality #Schools #SmartBuildings #Sensors #CO2 #PM2.5 #HVAC #BaltimoreSchools #EdTech #IndoorAirQuality #HealthTech #ConnectedDevices #Technology #Business #FexingoBusiness #BusinessPodcast #InternetOfThings Keep every episode free: buymeacoffee.com/fexingo
