ESP32 Garage Door Opener Kit - Auto Open and Close via Phone BLE
Door Open Status Monitor Kit - Automate Your Garage with ESP32 BLE Phone Detection and Auto-Close
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine arriving home, and your garage door automatically opens as you approach, then closes itself 30 seconds later. This kit lets you build that exact system - an ESP32-C3 controlled relay that detects your phone's BLE signal and triggers the door mechanism. No keys, no remotes, just seamless entry.
What You'll Build
You'll assemble a compact, battery-friendly circuit that reads your smartphone's Bluetooth MAC address. When the ESP32-C3 detects your phone is within a few meters, it activates a relay to open your garage door. After a timed pause, it de-energizes the relay to close, giving you a hands-free, secure access control system that fits inside a small enclosure.
What You'll Learn
- Programming an ESP32-C3 to scan for Bluetooth Low Energy devices and identify a specific phone
- Interfacing a 5V relay module with a microcontroller for switching high-current loads
- Implementing a timing function to auto-close after 30 seconds using software logic
- Soldering components onto a prototype PCB and mounting inside an ABS enclosure for a finished product

Who This Kit Is For
This kit is ideal for school students in ATL Tinkering Labs or CBSE classes 9-12 exploring IoT and automation. It's also a perfect starter project for B.Tech ECE/EEE freshmen at colleges like IITs, NITs, or VIT, and for participants in Smart India Hackathon looking for a quick, working prototype.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.

Do I need any additional tools besides what's in the kit?
The kit includes a soldering iron and solder wire, so you have everything needed for assembly. A computer with a USB port for programming the ESP32-C3 is required, but not included.
Can this work with multiple phones, not just mine?
The default code is configured for a single BLE MAC address, but you can easily modify the sketch to recognize additional phones by adding their addresses in the code.
How far does the phone need to be for the door to open?
Range depends on BLE signal strength, typically 5-10 meters. You can adjust the RSSI threshold in the code to customize the trigger distance for your environment.
Door Monitoring - ESP32-C3 relay opens garage door when own phone BLE detected nearby. Auto-close after 30 seconds.
