Pins used for on/off actions and simple input/output tasks on the Arduino.

A tool in the Arduino IDE to view real-time data (sensor readings, debug messages) from the Arduino.

A function in Arduino code that runs once when the board starts up (powered or reset).

The term for Arduino programs (code).

Software for writing, compiling, and uploading code to Arduino boards.

Input/Output pins which allow the microcontroller to interact with sensors or actuators.

Initializes settings for the Arduino board, defining pin modes, serial communications, and other parameters.

Executes the core program logic repeatedly after setup() finishes. It's the main code loop.

A tool in the Arduino IDE to manage external libraries for different sensors and modules.

A module that allows communication between the Arduino and an LCD display using only 4 pins.

Choosing the specific Arduino board model (e.g., Uno, Nano) in the Arduino IDE.

A communication protocol that uses two pins (SDA and SCL) for data transfer.

Used to send and receive data between the Arduino and a computer via USB.

Choosing the communication port connected to your Arduino within the Arduino IDE.

Measures the intensity of sound.

Detects obstacles using infrared light.

Function to read analog values from an input.

Function to read digital input values (HIGH or LOW).

Rotates to specific angles for controlling movement.

A specific value used to determine an action (e.g. 300 for soil moisture).

The quality of air inside buildings, encompassing factors like temperature, humidity, and presence of pollutants.

An IoT system using sensors to monitor and manage air quality indoors by detecting parameters like temperature, humidity, VOCs, CO2, PM10, PM2.5, CO, and NO2.

The system uses sensors like DHT11 (temperature/humidity), CCS811 (VOCs/CO2), SDS011 (PM10/PM2.5), and a multi-gas sensor (CO/NO2).

Poor IAQ can lead to respiratory problems, cardiovascular diseases, and even death.
