Flame Sensor Module (IR Flame Detection Sensor)

The Flame Sensor Module is designed to detect fire or flame sources by sensing infrared light emitted from flames. It is commonly used in fire detection systems, safety alarms, and robotics projects. This module can detect flames within a certain distance and provides both analog and digital outputs for easy integration with microcontrollers such as Arduino, ESP8266, and ESP32 boards. With adjustable sensitivity and a compact design, it is suitable for DIY electronics, automation systems, and educational projects.
