Conventional approach to air pollution monitoring using tempo-spatial measurements with instruments and air quality meters is cumbersome, stressful and unable to offer continuous monitoring. An Internet of Things (IoT) – based air pollution monitor using low cost micro-scale sensing technology was designed and developed. This system is convenient, cost effective and offers round the clock monitoring. The IoT-based air pollution monitoring system comprises of a sensor node, microcontroller (MC), internet gateway and a cloud server. Data is transmitted to ThingSpeak cloud server through HTTP command. The results are displayed on ThingSpeak webpage and remotely accessed.  Three separate hardware devices were developed and deployed in three different locations within Kaduna city. These areas are Kakuri industrial layout, Ahmadu Bello way commercial center and Gonin Gora residential area. The results from these locations which are remotely assessed, indicated that the developed devices offer continuous monitoring of air pollution with minimal human intervention. Furthermore, using percentage difference, the results from the IoT – based air pollution monitor are compared with those of conventional air quality meters and found to be accurate with a tolerance value of  +5%.
