ESP32-C3 BLE Garage Door Opener & Window Alarm Kit
Build a BLE Proximity Garage Door Opener & Window Alarm with ESP32-C3
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Walk toward your garage and the door rises automatically just because your phone is in your pocket. Or get an instant alert the moment a window is cracked open. This kit lets you build both: a BLE-driven garage door controller and a magnetic reed switch window alarm, all on the compact ESP32-C3. It's hands-on IoT that puts real home automation in your hands.
What You'll Build
You'll assemble a two-in-one smart security device. The ESP32-C3 scans for your phone's Bluetooth MAC address and triggers a 5V relay to open the garage door; after 30 seconds it auto-closes. At the same time, you'll wire a reed switch as a window sensor - when the magnet separates, the board can sound a buzzer or send a notification. Everything sits inside the included ABS enclosure, creating a neat, functional gadget you can install right at home.
What You'll Learn
- Program the ESP32-C3 to detect a specific BLE device (your phone)
- Drive a 5V relay module safely using a flyback diode
- Read a magnetic reed switch as a digital input for security monitoring
- Solder components on a prototype board and house them in a durable box

Who This Kit Is For
Secondary school students (CBSE Class 11-12, ATL Tinkering Labs) exploring IoT, B.Tech ECE/EEE freshers building mini projects, and participants in Smart India Hackathon or college tech fests. Soldering is involved, so we recommend ages 12+ with adult supervision.
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.
What if I get stuck during the build?

Can this actually open my real garage door?
Yes, the relay terminals can connect to most automatic garage door opener trigger inputs. We provide a wiring guide.
Does it need a separate power supply?
The ESP32 is powered via the included USB cable; the relay module uses the board's 5V pin. For high-current openers, an external supply may be needed - guidance is included.
Is the code pre-loaded on the ESP32?
No, you will upload the Arduino sketch using the Micro USB cable. Full code walkthrough and line-by-line explanation are provided.
Window Security - ESP32-C3 relay opens garage door when own phone BLE detected nearby. Auto-close after 30 seconds.
