Assignment 2 Answer

Introduc on:

In this Internet of Things (IoT) project, we build a model of a smart home equipped with diverse sensors, all programmed using

so ware and Arduino for comprehension and opera on The primary aim of the smart home is to enhance convenience and safety, ensuring the avoidance of any poten al hazards

Employ an appropriate set of tools to develop your plan into an IoT applica on (P5)

1 Introduc on:

We u lize both the Arduino Starter Kit and the Arduino So ware sourced from these pla orms to assist in the construc on of the smart home project as we build this model

2 Implementa on from design

The smart home system uses the following components:

This descrip on outlines the process of connec ng the DHT11 temperature and humidity sensor to the Arduino Uno The detailed instructions involve connec ng the Vcc and GND pins of the DHT11 to the 5V and GND pins of the Arduino Uno, respec vely Addi onally, the signal pin of the DHT11 is connected to pin 3 of the Arduino Uno This sequence of connec ons serves to provide power to the sensor and establish communication between the Arduino Uno and the DHT11, enabling the Arduino to read temperature and humidity data from the sensor

Step 3:

This step outlines the procedure for connec ng the MQ2 gas sensor to the Arduino Uno It involves connec ng the power (VCC) and ground (GND) pins of the MQ2 sensor to the 5V and GND pins of the Arduino Uno, respec vely Addi onally, the signal pin of the MQ2 is linked to analog pin A0 on the Arduino Uno This con guration ensures that the sensor receives power and enables the Arduino to read the analog signal from the MQ2, facilita ng the detection of various gas concentra ons

This step demonstrates the process of connec ng the HC-SR04 ultrasonic distance sensor to the Arduino Uno To supply power, the VCC and GND pins of the HC-SR04 are linked to the 5V and GND pins of the Arduino Uno, respec vely Furthermore, the Trig pin of the HC-SR04 is connected to pin 6, and the Echo pin is connected to pin 7 on the Arduino Uno This con gura on enables the Arduino to both control and gather data from the sensor, facilita ng the measurement of distance using ultrasonic waves

Step 5:

The illustra on illustrates the connec on process for a buzzer speaker to an Arduino Uno Power is supplied by linking the VCC and GND pins of the buzzer speaker to the 5V and GND pins of the Arduino Uno, respec vely Furthermore, the I/O pin of the buzzer speaker is connected to pin 4 on the Arduino Uno, enabling the Arduino to manage the buzzer speaker and produce audible signals to indicate speci c events or conditions within the smart home environment

Arduino Uno

The Arduino Uno R3 SMD is a varia on of the Arduino Uno R3 development board, dis nguished by the inclusion of a Surface Mount Device (SMD) in place of a tradi onal component

The main func ons of the Arduino Uno R3 SMD include:

• Development of Electronic Projects:

The Arduino Uno R3 SMD serves as a versa le pla orm for crea ng and tes ng electronic devices It allows the connec on of various components such as sensors, LEDs, control circuits, and motors to facilitate a range of ac vi es

informa on processing

• Interac on and Connec vity:

The Arduino Uno R3 SMD is equipped with mul ple pins that enable connec ons to external components like sensors, motors, and displays These pins provide a means to interact with the surrounding environment

HC SR04:

The HC-SR04 ultrasonic sensor is widely recognized for its applica on in determining the distance between a sensor and an object using the time- - ight concept of

The HC-SR04 ultrasonic eye's primary job is to:

Measurement of Distance : The HC-SR04 Ultrasonic Sensor emits ultrasonic waves, measures the me taken for the signal to

return a er interac ng with an object, and calculates the distance between the sensor and the object based on the speed of sound

in the air This enables non-contact distance measurement The HC-SR04 operates without physical contact with the object, making

it suitable for applica ons where a non-intrusive distance measurement is required

Accurate and fast : The HC-SR04 ultrasonic sensor is typically u lized for distance measurement with notable precision and

impressive speed Its rapid response mes enable e icient execu on of ac ons or controls based on distance measurements MQ2 Func on:

The MQ2 is a gas sensor designed to detect a range of gases, including methane, propane, butane, and smoke It is widely employed for tasks such as gas leakage detec on and air quality monitoring The sensor o ers analog output that is propor onal to the concentra on of the detected gas

Buzzer Func on:

The buzzer serves as an auditory signaling device, genera ng sound or tones in response to an applied electrical signal It nds applica on in diverse projects where it is employed for purposes such as alarms, noti ca ons, or signaling speci c events

How does the system operate?

A er connec ng the wires for the devices and supplying power:

When the HC SR04 sensor registers a distance signal within the 50cm range, it triggers the SG90 servo motor to automa cally rotate 90 degrees, thereby opening the system's door

The system monitors MQ2 sensor values, and if the gas reading surpasses 100, the buzzer ac vates to no fy the user of a poten al gas leak inside the house

LCD I2C func on:

LCD I2C is a display screen

It displays temperature and humidity

3 Program Compiler on Arduino

Step 1: Open App Arduino

Step 2: Input code in app Arduino

Clicking on the checkmark above the applica on will display an output like this, signifying that the code is valid and ready for use

4 Error and Problem when deploying / implement project:

The repeti ve crashes during program uploads in the Arduino IDE may stem from a con ict with a concurrent Logitech program process

To ensure compa bility with Arduino, it is necessary to acquire knowledge of and install the Arduino IDE since it is unable

to automa cally iden fy the suitable Board and Port

A substan al amount of me was invested in resolving a coding issue; This challenge arose due to the considerable heat generated by the microprocessor on the Arduino board

Run end user experiments and examines feedback (P6)

1 Introduc on

In this segment, we will provide an explana on of the opera onal principles embedded in the code

2 Code implements func ons in detail

The code sec on will include the declara on of Arduino pins linked to the temperature and humidity sensor, gas sensor, buzzer, and servo motor within the smart home system

input, designs the Trig and Echo pins of the HC-SR04 as outputs, and sets up an output pin for the relay

In this code snippet, the program retrieves temperature and humidity data from the DHT11 sensor and validates the data reading process for any errors In the event of an error, a corresponding message is displayed on the screen Contrary, if no errors are encountered, the acquired values are printed on the serial monitor Following the data retrieval, the code compares the temperature values with a prede ned threshold of 30 degrees If the temperature reading surpasses 30 degrees, the program

ac vates the fan to mi gate the room temperature

This code snippet reads input from the HC-SR04 distance sensor, computes the detected distance, and takes ac on accordingly If the measured distance falls below 50cm, it triggers the signal pin of the servo, prompting the servo to rotate 90 degrees and open the door Contrary, if the measured distance exceeds 50cm, the servo rotates back to 0 degrees, maintaining a sta onary posi on and indicating that the door is closed

3 Test case

1 Sensor distance Someone comes to the

4 Test case summary

The door is programmed to open when the measured distance is less than 50cm In such cases, it automa cally swings 90 degrees but reverts to its original posi on at 0 degrees if the distance exceeds 50cm The buzzer is triggered once the gas level reaches the predetermined warning threshold Connec ng the system to a computer allows for real- me monitoring of sensor data
