IoT Smart Door Lock Using ESP32, Solenoid Lock & Blynk App
The ESP32 communicates with the Blynk IoT cloud via Wi-Fi, providing real-time control and status monitoring. The solenoid lock is controlled through a 2-Channel Relay Module, making the entire setup safe, reliable, and fully automated.
Key Details About Iot Smart Door Lock Using Esp32, Solenoid Lock & Blynk App
Traditional key-based door locks can be easily lost, duplicated, or even broken. To solve this problem, smart automation and AI-based technology bring a modern solution — a Smart Door Lock System using ESP32, Face Recognition Camera ( ESP32 -CAM), and IoT ( Blynk App / IFTTT / Firebase / Google Assistant). This project allows you to:
This project implements a Smart Door Lock System using the ESP32, a 4x4 matrix keypad, a servo motor, and the Blynk IoT platform. It allows users to unlock the door either by entering a passcode on the keypad or by using a button on the Blynk mobile app . This hybrid system ensures secure and flexible access control for modern smart homes.
ESP32 Smart Lock System
In this project, I've built a Smart Lock System using the FireBeetle 2 ESP32 -C6, a DFRobot Capacitive Fingerprint Sensor, and the Blynk IoT App . This smart system allows you to unlock your lock in three different ways — Locally using your fingerprint, Remotely through the Blynk IoT app , or Manually using a push button from inside the room. The relay automatically switches OFF after 2 ...
Perfect for smart homes, school projects, or IoT experiments — this project teaches you how to integrate hardware with cloud-based platforms like Blynk to create powerful connected systems.
Esp32 with solenoid door for blynk
Hi, I want to control Door Lock /Unlock from Blynk App . But whenever I connect my project, the relay will auto switch on and the solenoid door stay unlocked. Problem: The relay will always on and solenoid door stay unlocked. The PIR Motion sensor always detect motion, ( but I do not really mind it because I just want it to show notification and then I will put delay for 30 mins for the demo ...
Overview This project is a Smart Door Lock System utilizing an ESP32, multiple sensors, and actuators to provide secure access control. The system integrates with Blynk , enabling remote monitoring and control via a mobile app .
Building a Smart Door Lock System with ESP32
