When 9-12VDC is applied, the slug pulls in so it doesn’t stick out and the door can be opened. It’s basically an electronic lock, designed for a basic cabinet, safe or door. OLED possesses high application potential for virtually all types of displays and is regarded as the ultimate technology for the next generation of flat-panel displays.ġ2V Solenoid lock has a slug with a slanted cut and a good mounting bracket. In contrast to LCD technology, OLED does not require a backlight. OLED (Organic Light-Emitting Diode) is a self-light-emitting technology composed of a thin, multi-layered organic film placed between an anode and cathode. The package includes display board, display,4 pin male header pre-soldered to board. The display module can be interfaced with any microcontroller using SPI/IIC protocols. This is a 0.96 inch blue OLED display module. In both circumstances, the system will return the matching result, success or failure. For 1:1 matching, the system will compare the live finger with a specific template designated in the Module for 1: N matching, or searching, the system will search the whole finger library for the matching finger. When matching, the user enters the finger through an optical sensor, and the system will generate a template of the finger and compare it with templates of the finger library. The system will process the two -time finger images, generate a template of the finger based on processing results, and store the template. When enrolling, a user needs to enter the finger two times. There’s a red LED in the lens that lights up during a photo so you know its working.įingerprint processing includes two parts: fingerprint enrollment and fingerprint matching (the matching can be 1:1 or 1: N). You can also enroll new fingers directly- up to 162 fingerprints can be stored in the onboard FLASH memory. Connect to any microcontroller or system with TTL serial, and send packets of data to take photos, detect prints, hash, and search. The R305 Fingerprint Sensor has a high powered DSP chip that does the image rendering, calculation, feature-finding, and searching. Note: Ignore 4x4 Keypad in the above image. The component purchase link is given below.ĮSP32 ESP-32S Development Board (ESP-WROOM-32) All the components can be easily purchased from Amazon. The PCB board Gerber file and Source Code/Program written in Arduino IDE is shared below.įollowing are the components required for this Security System Project. The 0.96″ SSD1306 OLED Display will display the status of matched/unmatched finger and door locking and unlocking status. We will use a Solenoid valve to lock/unlock the door. We will simply interface the R305 Fingerprint Sensor Module with ESP32 Development Board. So in this project, we will learn how to make ESP32 Fingerprint Sensor Based Door Lock Security System. It gives a high level of security than other security systems. The main feature or specialty of the fingerprint is that it is unique. We have seen a Password-based security system and RFID based security system, which is insecure and anyone can have access. This project is a fine combination of “ Biometrics technology” and “ Embedded system technology”. The fingerprint-based security system can be used in many places like Industries, Offices, and Colleges or even at our home. Fingerprint sensor-based is one of the safest door locking system as it has the ability to identify and distinguish every person individually without making any error. Security is a major concern in our day to day life, and digital locks have become an important part of these security systems. 10 Source Code: ESP32 Fingerprint Sensor Door Lock Security System.9 Source Code: Enrolling the Fingerprint.6 Circuit: ESP32 Fingerprint Sensor Door Lock Security System.
