Flame Sensor Module 4 Pin

Flame Sensor Module

The Flame Sensor Module 4 Pin is a compact and versatile sensor designed to detect open flames or other light sources emitting infrared (IR) radiation in the wavelength range of 700nm-1100nm.

It is particularly sensitive to the IR spectrum produced by flames, making it ideal for fire detection applications. The module can also be used as a general IR detector for projects requiring broad-spectrum detection. It features both digital and analog outputs, allowing for flexible integration into microcontroller-based systems like Arduino or Raspberry Pi.

Its adjustable sensitivity and compact design make it suitable for a wide range of applications, from fire alarms and safety systems to flame-detecting robots and educational prototypes.

FEATURES :

• 4-Pin Interface: Includes VCC (power), GND (ground), DO (digital output), and AO (analog output) for easy integration.
• High Sensitivity: Detects flame or light sources with wavelengths between 700nm and 1100nm.
• Adjustable Sensitivity: Features a built-in potentiometer to set the detection range.
• Digital Output (DO): Normally LOW; goes HIGH when a flame is detected.
• Analog Output (AO): Provides a real-time voltage signal that drops when a flame is detected, allowing for precise measurement.
• Detection Range: Up to 100 cm (adjustable, depending on flame size).
• Detection Angle: Approximately 60 degrees, highly sensitive to flame spectrum.
• Operating Voltage: 3.3V – 5V.
• Low Power Consumption: Maximum current draw <7mA.
• LED Indicators: Includes a power LED and a signal detection LED for easy status monitoring.
• Comparator Chip: Uses LM393 for stable and reliable readings.
• Driving Ability: >15mA, ensuring compatibility with most microcontroller inputs.
• Compact Size: PCB dimensions approximately 3.2cm x 1.4cm.
• Fast Response Time: Provides quick and accurate detection.
