Flame Detector Module 3 Pin Fire Sensor FDM-3-FS

Product Overview

The module featured in the document is the ADIY Flame Sensor Module. It operates on the principle of optical wavelength detection, utilizing a photo transistor that specifically reacts to light sources emitted by fires or flames within a targeted infrared spectrum. The board features a front-facing infrared receiver probe that pipes data into an onboard comparator chip alongside an adjustable potentiometer, enabling dual outputs through raw analog voltage monitoring and customizable binary digital switching thresholds. It is highly popular in DIY electronics, robotics, and automation for constructing fire alarms, smart firefighting robots, and automated fuel shutoff systems across domestic and industrial applications.
