Cellular IoT plays a crucial role in air quality monitoring systems by providing real-time data and connectivity. Air quality monitoring systems are networks of sensors and devices that measure various air pollutants in real-time. By leveraging technologies like LoRaWAN or NB-IoT for low-power, long-range connectivity, these systems ensure timely alerts and responses to take timely actions. With improved accuracy and coverage through distributed sensor networks,it can save energy and resource of up to 20%. Air quality monitoring is a proactive measures to combat air pollution and showcase commitment to environmental sustainability.
