Garage Smoke Alarm Kit
Garage Smoke Alarm Kit – Dual ESP8266 IoT Fire Monitoring System
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 a single sensor triggering a silent alert before your garage fills with smoke, logging temperature, humidity, pressure, and smoke concentration to a live dashboard on your laptop. This kit lets you build exactly that: two ESP8266 nodes that publish environmental data to an MQTT broker, which Node-RED visualizes with real-time charts and historical logs. Perfect for a car garage, workshop, or college IoT project where early fire detection is critical.
What You'll Build
A fully functional two-node wireless monitoring network: one node with DHT22 and BMP280 for ambient conditions, another with an MQ-2 smoke sensor and OLED display. Both transmit via MQTT to a broker on your laptop, where Node-RED plots temperature, humidity, pressure, and smoke level over time, and triggers a visual alarm when smoke thresholds are crossed.
What You'll Learn
- Configuring ESP8266 as MQTT clients with ArduinoJson payloads
- Setting up Mosquitto MQTT broker and Node-RED flows
- Calibrating the MQ-2 smoke sensor for early garage fire detection
- Integrating multiple sensors (DHT22, BMP280, OLED) into a single node’s code

Who This Kit Is For
Engineering students (B.Tech ECE/EEE) building IoT-based fire safety capstone projects, Smart India Hackathon participants prototyping industrial monitoring solutions, and final-year B.Tech/B.E. students from IITs, NITs, VIT, or BITS Pilani who need a ready-to-deploy wireless sensor network for their major project. Also suited for ATL Tinkering Lab mentors demonstrating MQTT data pipelines.
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?
Open the AI companion from the QR code and describe the issue; you’ll get instant troubleshooting steps. If you still need help, WhatsApp our support team for real-time guidance.
Can I connect the dashboard to a cloud platform instead of my laptop?
Yes, the Node-RED flow can be extended to forward data to platforms like ThingSpeak or Adafruit IO. The AI companion includes examples for cloud integration once the local broker is working.
Do I need soldering equipment?
Basic soldering is required to assemble the two nodes on the PCB prototype boards. The included breadboard is for initial prototyping, but the final build demands soldered connections for reliability in a garage environment.
How quickly will I see live data on the dashboard?
The step-by-step guide walks you through MQTT and Node-RED setup; you’ll see data flowing within 2-3 hours. Completing the full permanent build, including soldering and mounting, takes the full 5-6 hours.
