Importance and Utility of SMS+Notifications

In today's fast-paced world, staying connected and informed is crucial. The ability to receive real-time notifications and alerts can greatly enhance our daily lives, whether it's monitoring home security, tracking important events, or managing industrial processes. SMS+Notifications with Arduino offers a cost-effective and versatile solution to create an interactive notification system that can be customized to meet specific needs.

Project: Building an Interactive Notification System

This project aims to demonstrate how to build an interactive notification system using Arduino and SMS capabilities. The system will allow users to receive notifications via SMS when specific events occur, such as temperature exceeding a threshold, motion detection, or a door opening. The project will focus on integrating Arduino with a GSM module to send and receive SMS messages, as well as leveraging various sensors and actuators to trigger notifications.

Examples:

Example 1: Temperature Alert

#include <OneWire.h>
#include <DallasTemperature.h>

#define ONE_WIRE_BUS 2

OneWire oneWire(ONE_WIRE_BUS);
DallasTemperature sensors(&oneWire);

void setup() {
  sensors.begin();
  Serial.begin(9600);
}

void loop() {
  sensors.requestTemperatures();
  float temperature = sensors.getTempCByIndex(0);

  if (temperature > 30) {
    sendSMS("Temperature Alert: High temperature detected!");
  }

  delay(5000);
}

void sendSMS(String message) {
  // Code to send SMS using GSM module
  // Implementation details depend on the specific GSM module used
}

Example 2: Motion Detection Alert

#define PIR_PIN 2

void setup() {
  pinMode(PIR_PIN, INPUT);
  Serial.begin(9600);
}

void loop() {
  int motionValue = digitalRead(PIR_PIN);

  if (motionValue == HIGH) {
    sendSMS("Motion Alert: Motion detected!");
  }

  delay(500);
}

void sendSMS(String message) {
  // Code to send SMS using GSM module
  // Implementation details depend on the specific GSM module used
}

Example 3: Door Open Alert

#define DOOR_PIN 2

void setup() {
  pinMode(DOOR_PIN, INPUT_PULLUP);
  Serial.begin(9600);
}

void loop() {
  int doorValue = digitalRead(DOOR_PIN);

  if (doorValue == LOW) {
    sendSMS("Door Alert: Door opened!");
  }

  delay(500);
}

void sendSMS(String message) {
  // Code to send SMS using GSM module
  // Implementation details depend on the specific GSM module used
}
