Monitoring.

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%.
