⚙️ ResQTemp — Smart Temperature & Rescue Alert System

Course: Computer Organization & Assembly Language (COAL)
Semester: 3rd

📘 Project Overview

ResQTemp is a microcontroller-based smart temperature control and rescue alert system integrating Assembly-level programming with IoT and GSM communication.
It demonstrates how low-level hardware control (in Assembly) can synchronize with modern IoT automation to enhance safety and real-time monitoring.

The project monitors temperature using an LM35 sensor, controls fan and LED responses, and triggers rescue alerts via SMS and IoT dashboard after a safety delay if overheating persists.
Through an ESP8266 web interface, users can remotely view temperature data, device status, and location-based alerts in emergency mode.

🧩 Problem Statement

Conventional temperature monitoring systems lack intelligent decision logic and remote visibility.
In industrial or laboratory environments, a delayed response to overheating can lead to serious equipment or safety issues.

ResQTemp bridges this gap by merging:

  • Precision hardware control (Assembly-level logic)
  • Smart IoT connectivity
  • Real-time rescue response via automated SMS and web alerts

🎯 Objectives

  • Implement a temperature monitoring system using Assembly language on Arduino.
  • Activate safety outputs (LED/Fan) when temperature crosses threshold.
  • Introduce a 15-second delay before triggering emergency mode (avoiding false alerts).
  • Send a rescue SMS using SIM900A and update IoT dashboard via ESP8266 after the delay.
  • Display live readings and system status on a hosted IoT web page.
  • Optionally share GPS/location data for emergency tracking.

🧠 System Overview

Component Type Description
Microcontroller Arduino UNO programmed in Assembly (COAL core)
Sensor LM35 – Temperature sensor (analog input)
Outputs LED indicator, Cooling Fan, Buzzer
IoT Module ESP8266 Wi-Fi Module
GSM Module SIM900A — sends rescue SMS automatically
Web Page HTML + CSS dashboard showing live data & alerts
Language Stack Assembly (Arduino), C++ (IoT & GSM logic), HTML/CSS (Web UI)

🔬 Working Principle

  1. The LM35 sensor outputs an analog voltage proportional to temperature.
  2. Arduino executes Assembly instructions to:
    • Compare current temperature with threshold
    • Control fan/LED indicators
    • Start a 15-second timer if overheating continues
  3. If temperature remains high after 15 seconds:
    • Arduino signals the ESP8266 to update IoT dashboard
    • Arduino triggers the SIM900A module to send a rescue SMS to predefined numbers
  4. The ESP8266 dashboard displays:
    • Current temperature
    • System status: Normal / Overheat / Rescue Mode
  5. Users can monitor and control the system remotely via the IoT dashboard while receiving immediate SMS alerts.

🧰 Hardware Requirements

  • Arduino UNO
  • LM35 Temperature Sensor
  • ESP8266 Wi-Fi Module
  • SIM900A GSM Module
  • LED, Fan, Buzzer
  • Breadboard, Jumper Wires, Resistors
  • Power Supply (5V)

💻 Software Requirements

  • Arduino IDE
  • Assembly/C++ Compiler Support
  • HTML + CSS for Web Dashboard
