Room Temperature Monitor

Smart RoomTemperature Monitor

Overview

Introducing the Smart Temperature Monitor, an innovative solution designed to provide accurate and real-time temperature readings. Engineered with precision, this project harnesses the power of an Arduino Uno R3, a 16x2 LCD display, and a TMP36 temperature sensor to deliver a user-friendly and reliable monitoring system.

Key Features

Accurate Temperature Measurement: The TMP36 temperature sensor ensures high accuracy in detecting ambient temperatures, providing precise data for various applications.
User-Friendly Display: The 16x2 LCD screen offers a clear and easy-to-read interface, displaying temperature readings in real-time, making it accessible for users of all skill levels.
Arduino Uno R3: At the heart of the system is the Arduino Uno R3, renowned for its versatility and reliability, which ensures seamless integration and operation of all components.
Compact and Portable Design: The Smart Temperature Monitor is compact and lightweight, making it easy to deploy in various environments, from home and office spaces to industrial settings.

How It Works

The Smart Temperature Monitor utilizes the TMP36 sensor to measure the ambient temperature. The sensor outputs an analog voltage that is proportional to the temperature, which is then read by the Arduino Uno. The microcontroller processes this data and displays the temperature on the 16x2 LCD screen in a clear and concise format. The system is powered via USB or an external power supply, ensuring flexibility and ease of use, and you can use the potentiometer to adjust the brightness of the LCD screen.

Applications

Home Automation: Monitor and maintain optimal temperatures in your living spaces.
Greenhouses: Ensure plants are kept in ideal growing conditions.
Industrial Settings: Monitor machinery and equipment to prevent overheating.
Educational Projects: Ideal for students and hobbyists learning about electronics and programming

Conclusion

The Smart Temperature Monitor is a testament to innovative design and practical application. With its reliable performance, ease of use, and accurate measurements, it stands out as an essential tool for anyone needing precise temperature monitoring. Whether for personal use, educational purposes, or industrial applications, this project showcases the potential of integrating simple components to create a functional and impactful device.

Note from the Creator

This project was developed with the assistance of AI, and while every effort has been made to ensure accuracy and reliability, please note that I am a beginner in electronics and circuit design.

Arduino Code

C/C++

#include <LiquidCrystal.h>

// Initialize the library with the numbers of the interface pins
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

const int tempPin = A0; // TMP36 sensor pin

void setup() {
  lcd.begin(16, 2); // Set up the LCD's number of columns and rows
  lcd.print("Temp:"); // Print a static message to the LCD

  Serial.begin(9600); // Start serial communication for debugging
}

void loop() {
  int tempReading = analogRead(tempPin);
  float voltage = tempReading * 5.0 / 1024.0;
  float temperatureC = (voltage - 0.5) * 100; // Convert the voltage to temperature in Celsius

  lcd.setCursor(0, 1); // Set the cursor to the second line
  lcd.print(temperatureC);
  lcd.print(" C  "); // The extra spaces help clear any leftover characters from previous readings

  Serial.print("Temperature: ");
  Serial.print(temperatureC);
  Serial.println(" C");

  delay(1000); // Wait a second between readings
}
