Abstract: There has been a significant increase in the attention given by researchers to air quality monitoring due to its direct impact on human health. This paper presents the design and development of a low-power, long-range-based air quality monitoring device with 66 days of battery life and measurements in 1 h intervals. The proposed design uses a SEN54 sensor that can measure various environmental parameters including temperature, humidity, volatile organic compounds, and particulate matter levels. The performance of the air quality monitoring system is evaluated by installing it in multiple locations. The ThingSpeak IoT platform service analyses and visualises the data collected by the sensor node to provide real-time values for temperature, humidity, volatile organic compounds, and particulate matter. The best part of this visualisation is the presentation of the battery voltage data which serves as a helpful reminder to users to change the battery when needed.
