Project overview
Three flame sensors mounted at different angles let the robot work out roughly where a flame is rather than only whether one exists. It turns to centre the strongest reading, approaches to a fixed standoff distance, then runs a small pump to direct water at the source.
The standoff matters. A robot that drives all the way into the flame is not demonstrating fire fighting, and it also tends to melt. The approach stops at a set distance measured by the ultrasonic sensor, which is an easy thing to point at during questioning.
For safety the project is demonstrated on a candle-scale flame in a controlled setup, and the robot returns to a standby state once the flame sensors stop reading. Never demonstrate it near curtains, paper or anything else that can catch.
Features
- Directional flame detection using three angled sensors
- Turns to centre on the flame before approaching
- Stops at a fixed standoff distance instead of driving into the flame
- Pump-driven water jet with an aimed nozzle
- Returns to standby automatically once the flame is out
How it works
- 1The three flame sensors are read continuously and compared against each other.
- 2The strongest reading indicates which side the flame is on, and the robot rotates to balance the left and right sensors.
- 3With the flame centred, the robot advances while the ultrasonic sensor tracks the closing distance.
- 4At the standoff distance the robot stops and the pump runs, directing water through the nozzle.
- 5When all three sensors fall below the detection threshold, the pump stops and the robot returns to standby.
Components used
- Arduino Uno
- Three IR flame sensors

Questions about this project
Is it safe to demonstrate indoors?
It is designed for a small controlled flame such as a candle, on a clear surface, with nothing flammable nearby. Follow the demonstration guidance supplied with it and keep an adult or staff member present.
How far away can it detect a flame?
Detection of a candle-sized flame is reliable to roughly a metre indoors. Bright sunlight and halogen lamps interfere with IR flame sensors, which is worth noting in your report.
