LM393 IR Flame Detection Sensor Module Compact infrared flame detector module with LM393 comparator, designed for easy integration into Arduino and other microcontroller projects. Offers a simple 3wire or 4pin connection for fast prototype development and reliable detection of flame infrared emissions. Key benefits Easy integration: Standard 3wire or 4pin header supports common power and signal wiring for Arduino and most microcontrollers, reducing setup time. Reliable detection: Infrared receiver tuned to flame wavelengths works with the LM393 comparator to provide clear signal output for triggering alarms or control logic. Compact and modular: Small PCB module and standard pinout make it simple to mount on breadboards or custom PCBs for DIY kits and prototypes. Versatile use: Serves as a building block for fire detection experiments, robotics, safety prototypes, and educational projects. What it does and why you need it Detects infrared radiation from open flames and converts that detection into a usable electronic signal through the LM393 comparator. Solves the challenge of sensing flame presence in hobby and prototype systems without complex optics or processing. Provides a straightforward hardware interface so you can focus on your project logic instead of lowlevel sensor integration. Important attributes Chipset: LM393 comparator for signal conditioning. Interface: 3wire or 4pin header for power and signal connections, compatible with Arduino and similar controllers. Form factor: Compact PCB module suitable for breadboard and panel mounting. Performance: Designed for fast response to infrared emissions typical of flames, offering repeatable signals for control systems. Practical applications Home or workshop prototype: Integrate into a microcontrollerbased alert system for experimentation with stove or heater monitoring. Robotics: Use as a flameseeking sensor in educational robotics or demonstration projects. Electronics labs and DIY kits: Include in learning modules for teaching sensor interfacing and comparatorbased signal output. This module provides a straightforward, nononsense sensor solution for projects that require flame presence detection and easy connection to Arduino and other microcontroller platforms.
