Introduction
This Smart Home IoT project aims to create a smart home system that uses IoT devices to improve safety, convenience and energy savings for users The project includes a numeric keypad for access management and motion sensors, light variables, gas sensors and rain sensors to automatically control home appliances.
Employ appropriate tools to develop your plan into an IoT application (P5)
Introduction
In this section, we will look at how to choose the right hardware and software architecture for Smart Home IoT project development, including door lock numeric keypad, motion sensor, light sensor, sensor gas and rain variable.
Implementation of design
In this case, the system consists of a keypad with an LCD (Liquid Crystal Display) and an SG90 servo motor, combined with an Arduino Uno to create a secure and interactive control system through entering codes via the keypad and controlling the servo motor.
2) Why do you need to do that?
Combining the keypad, LCD, and SG90 servo motor helps establish a secure and convenient mechanism for door access By using the keypad to input codes and controlling the servo motor, users can easily control access to a specific space and ensure security.
3) How do you do it?
3.1) Setting up the keypad and LCD:
Step 1: Connect the keypad to the Arduino Uno using GPIO pins The keypad usually has rows and columns of buttons, and you'll need to connect the rows to specific GPIO pins and the columns to other pins.
Step 2: Connect the LCD display to the Arduino Uno using either the I2C interface or parallel interface Typically, the LCD will have output including data lines and control lines.
Step 3: Use the corresponding libraries (like Keypad.h and LiquidCrystal.h) to read data from the keypad and display information on the LCD When users input codes, the data will be displayed on the LCD.
Step 1: Connect the SG90 servo motor to the Arduino Uno The servo motor has three wires: one for power, one for ground, and one for signal Connect the power and ground wires to the power and ground of the Arduino, and connect the signal wire to a GPIO pin on the Arduino.
Step 2: Use the Servo.h library to control the SG90 servo motor from the Arduino This library allows you to adjust the rotation angle of the servo motor.
Step 3: Based on the code input from the keypad and displayed on the LCD, you can determine the corresponding actions For example, if the code is correct, you can control the servo motor to open the door by adjusting the rotation angle.
In summary, by combining the keypad, LCD, and SG90 servo motor with the Arduino Uno, you can create a secure and interactive door access system The process involves setting up the keypad and LCD, using the corresponding libraries to control and display data, as well as controlling the SG90 servo motor based on data from the keypad.
A motion sensor light is a sensor device used to detect motion in the environment and activate corresponding light fixtures or lighting devices It typically utilizes infrared or ultrasonic technology to detect changes in the surroundings.
2) Why do you need to do that?
Motion sensor lights help conserve energy and enhance convenience When a person moves within an area monitored by the sensor, the light system automatically turns on, ensuring sufficient illumination when needed, and turns off after motion is no longer detected This contributes to energy savings and improves security in the area.
3) How do you do it?
Step 1: Connect the power and ground pins of the motion sensor to the appropriate power and ground sources.
Step 2: Connect the signal pin of the motion sensor to a GPIO pin on the Arduino Uno Typically, the motion sensor will have a signal pin to send a signal when motion is detected.
Step 1: Use the Arduino IDE programming environment to write code.
Step 3: Write code to check the status of the motion sensor If motion is detected, the system will activate the light by controlling the related GPIO pin connected to the light After a period of no motion, the system will turn off the light.
3.3) Integration with the Light Fixture:
Step 1: Connect the light fixture to the Arduino Uno using the appropriate GPIO pin.
Step 2: Write code to control the GPIO pin of the light When the motion sensor detects motion, the system will turn on the light, and after a period of no motion, the system will turn off the light.
In summary, a motion sensor light combined with an Arduino Uno enables automatic activation of lights upon motion detection and turning off lights when motion is no longer detected The process involves connecting the sensor, programming the Arduino to read data and control the light, and integrating the system with the light fixture.
A photodiode sensor is a type of light sensor used to detect the level of light in the environment It operates by generating an electron current based on the amount of light it encounters.
2) Why do you need to do that?
Combining a photodiode sensor with a light fixture and Arduino Uno can create an automated light control system based on the natural light level in the environment This helps conserve energy, enhance convenience, and create a more comfortable living environment.
3) How do you do it?
Step 1: Connect the anode (positive pin) of the photodiode sensor to a stable power source, such as 5V on the Arduino Uno.
Step 2: Connect the cathode (negative pin) of the photodiode sensor to a GPIO pin on the Arduino Uno. 3.2) Arduino Programming:
Step 1: Use the Arduino IDE programming environment to write code.
