4 Pin Flame Detection Sensor Module – Infrared Fire Detector

The 4 Pin Flame Detection Sensor Module is designed to detect flames and fire sources by sensing infrared radiation. This module is commonly used in safety systems, robotics, and educational projects where early fire detection is required. Because it supports both analog and digital outputs, it offers greater flexibility compared to basic sensor modules.

This sensor works by detecting infrared light emitted from flames. As a result, it can quickly respond to the presence of fire within its detection range. Moreover, the onboard comparator allows users to adjust sensitivity using the built-in potentiometer. Therefore, it becomes easier to fine-tune the sensor based on different project needs.

In addition, the module operates on low voltage, which makes it safe for student projects and DIY electronics. Since it comes with four pins, it can provide both signal types to microcontrollers such as Arduino, Raspberry Pi, and ESP boards. Furthermore, the compact PCB design helps it fit easily into small enclosures and robotic systems.

The 4 Pin Flame Detection Sensor Module is suitable for fire alarm models, automatic fire-fighting robots, and smart safety demonstrations. However, for best performance, it should be used in indoor environments where direct sunlight or strong infrared sources are limited. Because of its stable output and adjustable sensitivity, it is widely preferred for learning and prototype development.

Overall, this sensor module is a reliable and practical choice for anyone looking to add flame detection capability to electronics projects.
