Internet of Things (IoT) devices that use multiple sensors, actuators, etc are finding their way into our
homes at an alarming rate. The need to store, access, and analyse the data from these devices
becomes increasingly a top priority, mainly due to the requirement to provide real-time monitoring of
activities happening within the home.
In this assignment, you will develop an active control system with the following specifications:
- Read data captured from IoT devices that have been stored in text files. The files contain a
day’s worth of data captured at hourly intervals. You are required to use the code provided (in
the appendix below) but adapt it to make use of structures. - Process data to activate/deactivate devices. The sensor data is used either to turn ON or OFF
devices within the rooms being monitored - Display state of devices based on location and/or time.
The following devices are used as part of the home monitoring system:
● Humidity sensors (used to turn ON or OFF a ventilation system)
● Internal and external temperature sensors (used to turn ON or OFF a heating system)
● Motion sensors (used to turn ON or OFF lights in that room)
Data Files
The data files containing the days’ worth of information have been provided (on the Moodle
assignment link) and contain information at which the sensor data has been recorded. The files are
named per the location where the data was recorded.
Each text file contains information in the following order:
timestamp, outside temperature and inside temperature, humidity, and motion sensors (6 samples
over a 1-hour slot i.e. one sample every 10 minutes)
timestamp outside
temperature
inside

Energy Consumption
Three files are available for data recorded in the living room, bedroom and kitchen. The data
loaded from these files are then used to: - Decide wherever to turn ON or OFF the associated device (e.g. heating, ventilation, and lights)
- Compute the energy consumption based on how long the devices have been ON on a daily
basis. Daily consumption in per KiloJoules (KJ) is calculated using equation 1.0 below
Daily Consumption (KJ) = Daily Heating Energy + Daily Ventilation Energy + Daily Light Energy
Equation 1.0 Energy Consumption
The information in Table 1.0 indicates the amount of energy consumed per hour when the
respective devices are ON.
Table 1.0 Energy Consumption
Heating 300KJ
Ventilation 250KJ
Lights 100KJ
Functionality and Marking Scheme
Your program will need the following functionality: - Read/load data from sensor files provided using the ReadDataFunction provided in
Appendix. Note you will need to request the user to provide a file location as a string for
each file before running this function.
a. TimeDat[] for the time
b. TempArr[][] for the temperatures
c. HumiArr[] for humidity
d. MotionArr[][] for motion sensors
(15 marks for loading data successfully from all three files)

Your system should therefore provide a menu system that provides options to the user by
using functions for the following: - Control the state of the devices (turn ON or OFF) based on the user’s specifications
It is expected the user will supply a threshold for each device, regardless of location, to turn
ON
(15 marks) - Calculate the energy consumption per day
It is expected you will use a 2D array (time v/s device) to store the states of the device at any
given time. E.g., one table per location. Each element in the array will contain either a 0
(OFF) or 1 (ON). The program will then use the total units when each device is ON to
calculate total energy (using equation 1.0 for every location and using table 1.0 to get hourly
energy).
Energy consumption calculate is to be added to an Energy Log (Energy.txt) with a timestamp
of the day that the information was calculated on
(30 marks) - Write the state of the devices on an hourly basis in three different files (and separate from
the ones you read in). If the file does not exist, the program should create one for you.
For each location, write to a follow-up file e.g., KitchenDevices.txt that displays for each
timestamp, wherever each device was ON or OFF
