# Counter Using Proximity Sensor with ESP8266 🚀



This repository contains a project that uses an **IR proximity sensor** and an **ESP8266 microcontroller** to count objects passing through a designated area. The count is displayed on a **7-segment display**, making it a practical solution for object detection and monitoring.



## 📜 Problem Statement



Develop a reliable counter system using IR sensors integrated with the ESP8266 microcontroller. The system should accurately track and count objects passing through a defined area, displaying the count on a 7-segment display.



## 🛠️ Features



- **IR Sensor-Based Object Detection**: Uses an IR proximity sensor for accurate object detection.

- **7-Segment Display**: Displays the count in real-time.

- **ESP8266 Microcontroller**: Provides efficient control and connectivity options.

- **Cost-Effective Solution**: Affordable and adaptable for IoT and automation projects.



## 📂 Project Structure



- **`counter_proximity_sensor.ino`**: Arduino code for the counter system.

- **`ESD_Report.pdf`**: Detailed report documenting the problem statement, theory, algorithm, source code, and conclusions.

- **`README.md`**: Documentation for the repository.



## 🔧 How to Run



### Hardware Requirements

1. **ESP8266 Microcontroller (e.g., NodeMCU)**

2. **IR Proximity Sensor**

3. **7-Segment Display (Common Cathode)**

4. Breadboard and Jumper Wires



### Software Requirements

1. **Arduino IDE**: Download from [here](https://www.arduino.cc/en/software).

2. **IRremote Library**:

   - Install via Arduino IDE:

     - Go to **Sketch > Include Library > Manage Libraries**.

     - Search for `IRremote` and install it.



### Steps to Run

1. **Circuit Connections**:

   - Connect the IR sensor's **OUT pin** to `D7` on ESP8266, **VCC to 3.3V**, and **GND to GND**.

   - Connect the 7-segment display's pins (`a` to `g`) to `D0` to `D6`.



2. **Upload Code**:

   - Open `counter_proximity_sensor.ino` in Arduino IDE.

   - Select the correct board (**NodeMCU 1.0 (ESP-12E Module)**) and port under **Tools**.

   - Click **Upload** to flash the code.



3. **Run the System**:

   - Power the ESP8266.

   - The IR sensor will detect objects, and the count will be displayed on the 7-segment display.

## 📘 Report Highlights



### Components Used

- **IR LED and Photodiode**: Used for emitting and detecting infrared signals.

- **ESP8266**: Provides Wi-Fi connectivity and serves as the primary microcontroller.

- **LM358 Op-Amp**: Used for signal amplification in the IR sensor module.

- **Variable Resistor**: Adjusts detection range.



### Algorithm

1. Initialize pins for the 7-segment display and IR sensor.

2. Read IR sensor output to detect object presence.

3. Increment the count if an object is detected.

4. Reset the count to 0 after reaching 9.

5. Update the 7-segment display with the current count.
