Detect Forest Fires Early with Your Own Arduino Uno & Flame Sensor Alarm System

Every part needed to build a working fire alarm that detects flames from 80cm—pre-tested for compatibility, with an AI build companion trained on exactly this circuit. Shipped from Bengaluru in 3-5 days.

Climate change makes early wildfire detection more urgent than ever. With this kit, young makers build a functional fire alarm that can spot a candle flame across the room. The KY-026 flame sensor reads infrared radiation, and you program an Arduino Uno to trigger a buzzer and light up a row of red LEDs—the closer the flame, the more LEDs glow, giving a clear analog intensity bar just like professional fire warning panels.

What You'll Build

You’ll assemble a breadboard circuit where the flame sensor feeds an analog voltage to the Arduino. As a flame moves closer, the board reads increasing intensity and progressively lights up three red LEDs. When the signal crosses a set threshold, the active buzzer sounds a continuous alarm. It’s a hands-on fire station siren that demonstrates sensor calibration, threshold logic, and visual alert systems—perfect for school exhibitions or tinkering labs.

What You'll Learn

• Interfacing an analog flame sensor with Arduino Uno and reading its output
• Writing conditional code to compare sensor readings and trigger an alarm
• Building an LED bar graph that represents analog fire intensity
• Applying early warning system principles to environmental monitoring

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Students from CBSE Class 8–12 use this for physics practicals and science exhibitions on environmental sensing. B.Tech ECE/EEE first-years rely on it for sensor lab introductions, while ATL Tinkering Labs adopt it for wildfire awareness activities. Even hobbyists at IIT/NIT/VIT hackathons start with this kit before moving to advanced IoT-based forest monitoring.
