Abstract:
This research work introduces a novel human detection sensor on an IoT node so as to
increase the efficiency of sensing human beings in a building, it also provide power
management and control since Nigeria supply far less than what was actually demanded,
based on the power baseline report submitted to the office of the vice president in 2015,
which stated that only 10% of the power demanded was supplied, these couple with the
fact that energy wastage is rampant in the country. This thesis presented an efficient
energy management in buildings using Internet of Things (IoT) by construction of an IoT
based human detection system and IoT based power management and control system.
The power management and control IoT board make use of contactless current sensor
which make the installation far easier, as many literature uses either the series resistance
method or the current transformer method for sensing flow of current through a given
load. The prototype was successfully implemented, installed and tested, the system was
developed to run in the real world and several data was generated. Based on the data
generated and analyzed the system was found to have 38% energy saving since the load
is always automatically off when no human being is in the office that it was installed.
