Lab Workbench Fire Monitor Kit with Arduino Uno + Sensor
Lab Workbench Fire Monitor Kit with Arduino Uno: Detect a Candle Flame and Sound an Alarm
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
A lit candle on your lab bench feels harmless until it tips over. This kit turns an Arduino Uno and a KY-026 flame sensor into a vigilant fire monitor that detects a candle flame from 80 centimeters away and triggers a loud buzzer while lighting up a red LED intensity bar. By the end of this build, you’ll have a working lab safety device that reacts to fire in real time.
What You'll Build
You’ll assemble a self-contained fire detection system that uses a flame sensor to measure the distance and intensity of a candle flame, then activates a buzzer alarm and a row of three red LEDs to show how close the flame is. Mount it on your workbench to alert you to unattended flames and understand the basics of analog‑to‑digital sensing.
What You'll Learn
- Connect and read an analog flame sensor with Arduino Uno
- Map analog sensor values to LED intensity levels for a visual bar
- Trigger a buzzer alarm based on calibrated distance thresholds
- Calibrate a fire detection system for a specific distance and flame type

Who This Kit Is For
This kit is perfect for ATL Tinkering Lab students, CBSE Class 5–10 science project builders, and young makers eager to build a real-world safety device. It’s also a popular hands-on introduction for B.Tech ECE first‑year labs exploring analog sensors and alert systems, and for Smart India Hackathon teams prototyping rapid fire‑detection demos.
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.
How far away can the flame sensor detect a candle?
The KY‑026 reliably detects a standard candle flame from up to 80 cm when properly calibrated. In our tests, it triggers the alarm at that distance, though strong ambient light may require a slight threshold adjustment.
What if my alarm doesn’t sound when I light the candle?
First check your wiring, especially the sensor’s analog pin connection. Then use the AI companion’s calibration guide — it walks you through adjusting the threshold in the code. You can also reach us on WhatsApp for real‑time help.
Can I use this kit to detect other flames, like a lighter or stove?
Yes, the sensor responds to any flame with sufficient infrared emission. You’ll need to recalibrate the distance thresholds for different flame sizes; the AI companion includes sample code tweaks for lighter and stove flames.
Is this kit safe for a 10‑year‑old to build?
Absolutely. The breadboard‑based assembly requires no soldering, and the 9V battery is safe to handle. We recommend adult supervision for first‑time builders to help with sensor placement and code uploading.
