Garage Smoke Alarm Kit v2
ESP8266 Garage Smoke Alarm Kit – Dual-Mode Fire Alert with SMS for Your Workshop
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Your garage or workshop often houses flammable liquids, vehicles, and tools that can overheat. This kit transforms an ESP8266 NodeMCU into a vigilant smoke and temperature guard. When MQ-2 gas levels rise or the DS18B20 detects dangerous heat, a loud buzzer screams and the system silently dispatches an SMS to your phone — all without you being on site. It’s a practical first step into smart home safety, built entirely by you.
What You'll Build
You will assemble a stand‑alone alarm station on a breadboard that reacts to two independent fire indicators: combustible gas/smoke concentration and ambient temperature exceeding a preset limit. The ESP8266 processes both sensors, logs readings, and triggers a piezo buzzer plus three red LEDs for visual warning. Simultaneously, it uses your home Wi‑Fi to send an SMS alert — no subscription or cloud account required, just a free webhook service we guide you through. The outcome is a fully functional prototype that can be mounted inside a garage or attic.
What You'll Learn
- Reading analog gas concentration values from the MQ-2 sensor and calibrating detection thresholds
- Interfacing the DS18B20 digital temperature probe over OneWire and setting over-temperature trips
- Programming the ESP8266 in Arduino IDE to handle sensor data, trigger alarms, and send HTTP‑based SMS via a simple API
- Building sensor fusion logic where both smoke and temperature must agree to activate the highest alert, avoiding nuisance alarms

Who This Kit Is For
This beginner kit is ideal for school students exploring IoT through ATL Tinkering Labs, CBSE Class 11–12 science projects, and early-year B.Tech ECE/EEE students at IITs, NITs, VIT, or BITS Pilani. It is also a rewarding weekend build for makers prototyping a garage safety device for the Smart India Hackathon health & safety track.
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?
Scan the QR code inside the box to access the AI companion trained on this kit; it can spot wiring errors and explain code logic. For additional help, message us on WhatsApp.
Does the SMS alert require a paid SIM or service?
No. The ESP8266 sends an HTTP request using your Wi‑Fi. We guide you to use a free webhook service like IFTTT or a Twilio trial account. No extra hardware or monthly fee is needed.
Can I install this alarm in my actual garage?
This is a functional prototype for learning. It will detect smoke and heat accurately, but we recommend using certified, UL-listed detectors for life safety. For a workshop or storage shed, it works as an experimental monitor.
Do I need any coding experience?
None. The AI companion provides the complete code, explaining each block. You’ll learn by uploading it to the NodeMCU and customizing alert thresholds — all with beginner-friendly comments.
Garage Fire — MQ-2 smoke and DS18B20 over-temperature together trigger dual-mode fire alarm with SMS via ESP8266.
