🚀 AI-Based Smart ATM Security System

ESP32 + Face Recognition + IoT + n8n Automation + Telegram Alerts

📌 Project Overview

This system uses ESP32-CAM with AI-based face recognition to secure ATM access. It integrates IoT cloud platforms, Telegram alerts, Google Sheets logging, and n8n automation workflows.

🧰 Components List

  • ESP32-CAM module
  • FTDI Programmer
  • PIR Motion Sensor
  • Buzzer
  • Relay Module
  • Power Supply

🔌 Circuit Connections

PIR Sensor → GPIO 13
Buzzer     → GPIO 12
Relay      → GPIO 14
FTDI TX    → U0R
FTDI RX    → U0T
VCC        → 5V
GND        → GND

🔄 System Flow

Motion Detected → Capture Face → AI Verification
        ↓
Authorized → Grant Access
Unauthorized → Trigger Alarm + Send Alerts
        ↓
Log to Google Sheets + ThingSpeak
        ↓
n8n Automation → Telegram Notification

💻 ESP32 Sample Code

#include "esp_camera.h"
#include 

const char* ssid = "YOUR_WIFI";
const char* password = "YOUR_PASS";

void setup() {
  Serial.begin(115200);
  WiFi.begin(ssid, password);
}

void loop() {
  Serial.println("Monitoring ATM...");
  delay(2000);
}

⚙️ n8n Automation Flow

Webhook Trigger → Telegram Alert → Google Sheets → ThingSpeak Update

📲 Telegram Bot Setup

Create Bot via BotFather:
/newbot

API Format:
https://api.telegram.org/bot/sendMessage

☁️ ThingSpeak Setup

🧠 AI Power Prediction

if motion_events > 50:
    power = "HIGH"
elif motion_events > 20:
    power = "MEDIUM"
else:
    power = "LOW"

🚀 Future Enhancements

  • DeepFace AI recognition
  • Anti-spoofing detection
  • Mobile app dashboard
  • Blockchain security logs
