Product Overview
The flame sensor module is designed to detect fire or flame sources using infrared light sensing technology. It responds to flame wavelengths typically between 760 nm and 1100 nm. When a flame is detected, the module outputs a digital signal and activates the indicator LED. The onboard potentiometer allows sensitivity adjustment, thereby enabling accurate detection based on distance and flame intensity. This module is suitable for fire alarm systems robotics and automation safety projects.

Installation Notes
Connect VCC to 3.3 V or 5 V supply and GND to ground. Connect the OUT pin to a digital input of the controller. Adjust the sensitivity using the onboard potentiometer so that the module detects flame at the required distance. Avoid exposing the sensor to strong sunlight as it may affect detection accuracy.
