The Octopus Flame Sensor is a simple infrared-based module that detects the presence of a flame or fire source. Part of the Octopus Electronic Bricks system, it connects directly to Arduino and compatible boards with a standard 3-pin interface — just plug and play, no breadboard required.

The module outputs a digital high/low signal when a flame is detected, with an on-board potentiometer to adjust the detection sensitivity. Fast response and high sensitivity make it suitable for fire detection alarms, firefighting robots, and safety monitoring projects.
