Heater-Control-System

This repository contains simulation links and code for an Automatic Heater Control System.
Created as an assignment for the upliance.ai Embedded Systems Internship.

Note:

1. BLE cannot be simulated on Wokwi. To test BLE functionality, hardware implementation is required.
2. main.cpp contains the code without BLE support.
3. main(BLE).cpp contains the code with BLE support.

Wokwi Simulation Link:

https://wokwi.com/projects/430502347775092737

Components Used:

• DS18B20 Temperature Sensor
• ESP32
• Servo Motor
• LED
• 4x4 Keypad
• Resistors

---

Variables:

• Target Temperature: Temperature set by the user using the keypad.
• MAX_TEMP: Temperature above which overheating is detected.

How to Use This Repository:

1. Download the ZIP or clone the repository.
2. Open the folder in PlatformIO (VS Code) and initialize it as a PlatformIO project.
3. Click Build to compile the code.
4. Click Upload to flash the code to your ESP32.
5. Use the Serial Monitor to view real-time debug messages and instructions.

Simulation Instructions (using Wokwi Link):

1. Open the simulation link provided above.
2. Enter the Target Temperature using the keypad.
3. Follow the instructions shown on the Serial Monitor.
4. Based on the temperature and input, the system will behave as follows:

System States:

State	Conditions	Action
HEATING	Target temperature entered, sensor temp < target	LED ON, Servo rotates
OVERHEATING	Sensor temp > MAX_TEMP (e.g., >100°C)	LED OFF, Servo rotates to 0
TARGET_REACHED	Temp within target ± threshold	LED OFF, Servo rotates to 0
IDLE	No target temp set or sensor temp > target	LED OFF, Servo rotates to 0
STABILIZING	Temp near target but still adjusting	LED/Servo state depends on temperature
