Access Control with Sanitization using ESP32CAM and Arduino Uno

A project I worked on to implement an access control system that also included a way to sanitize peoples hands as they went into a facility and also check their temperature with builtin camera survillence

Access Control Module

RFID and Biometric Access

The Access Control module handles secure entry using RFID cards and fingerprint sensors. The code segments within this module facilitate:

• RFID Authentication: The system verifies access using specific RFID card tags (VISITOR_TAG_1 and VISITOR_TAG_2) assigned to visitors.
• Biometric Access: Fingerprint-based authentication is implemented using functions such as fpsAccessMode() and enrollFingerprints().

User Interface and Control

Additionally, this module manages the user interface and control mechanisms, comprising:

• Servo Control: Functions like initServo(), openMode(), and closeMode() control servo motors for managing the entry door.
• LCD Interface: LCD functions (initLCD(), lcdPrintString(), etc.) display access-related messages and prompts for users.

Camera Module

Camera and HTTP Handling

The Camera module encompasses functionalities related to camera integration and HTTP request management. Although specific details are limited, the code segments suggest:

• Camera Operations: The camera uses an http server to stream image frames for taking pictures when a person is detected near the sanitization module
• HTTP Communication: The ESP32CAM uses HTTP to receive triggers to capture an image and also control the flash light. It sort of acts like an API for the camera

Sanitization Module

• Sanitizer Level Monitoring: Continuous monitoring of sanitizer levels through checkSanitizerLevel() function and associated sensor readings.
• Temperature Monitoring: Utilizes an infrared sensor (Adafruit_MLX90614) to gauge body temperature and trigger sanitation protocols (in this case trigger a buzzer) based on predefined temperature limits.
• Proximity Sensing: Utilizes ultrasonic sensors (initSonar(), getDistance()) to detect proximity and initiate sanitation measures based on predefined distance criteria.
