This is an example code written to showcase the usage of RF Module and WiFi to control a relay to lock and unlock a door. The ESP32 Dev Board is connected to a 433MHz RF Reciever and a Relay. You can ...

Abstract: In this paper, we propose a smart digital door lock system for home automation. A digital door lock system is equipment that uses the digital information such as a secret code, ...

This project integrates Arduino with RFID and keypad-based authentication to create a secure and versatile door lock system. It leverages real-time feedback via an LCD screen and controls a solenoid ...

RFID (Radio Frequency Identification) is an inexpensive and accessible technology. It can be used in many applications such as access control, security, asset tracking, people tracking, etc. You have ...

Abstract: We propose a novel wireless access monitoring and control system based on the digital door lock, which is explosively used as a digital consumer device. Digital door lock is an electronic ...

Radio Frequency Identification is widely used in contactless payment cards, National Highway Tollgate systems, and in security passes. By integrating an RFID reader with an Arduino, you will be able ...

For contactless key applications, the Marquardt NFC module is mounted inside the door handle, and also in the car’s centre console (inside the cabin). In the door handle, the 13.56MHz module couples ...

The behind-the-scenes mechanism that locks and unlocks your vehicle’s doors with the push of a button is the power door-lock actuator. Mounted inside the door, it includes an electric motor, gears and ...
