Fire / Flame Sensor Module (4P)

The Fire / Flame Sensor Module (4P) is a compact infrared-based detection module designed to sense the presence of fire or flame. It detects infrared light emitted by flames and provides both digital and analog outputs, making it suitable for quick fire detection and safety-related electronics projects. The onboard potentiometer allows easy sensitivity adjustment.

Technical Specifications:

• Detection Method: Infrared flame detection
• Detection Wavelength: ~760 nm to 1100 nm
• Operating Voltage: 3.3 V to 5 V DC
• Output Type: Digital (DO) and Analog (AO)
• Interface Pins: VCC, GND, DO, AO (4 Pins)
• Sensitivity Adjustment: Onboard potentiometer
• Detection Angle: Approximately 60°
• Detection Distance: Up to ~80 cm (depends on flame size and sensitivity setting)

Features:

• Detects flame and fire sources reliably
• Provides both analog and digital outputs
• Adjustable sensitivity via onboard trimmer
• Compatible with Arduino, ESP32, Raspberry Pi, and other microcontrollers
• Compact PCB with mounting hole for easy installation
• Low power consumption

Applications:

• Fire detection and alarm systems
• Flame monitoring systems
• Smart home safety projects
