Arduino Flame Detection Sensor Module🔥

Detect infrared flame signatures with this compact, high-sensitivity flame sensor module designed for Arduino, Raspberry Pi (with ADC), and other microcontroller platforms. Ideal for electronics components projects, robotics, and safety prototypes, it senses IR light in the 760–1100 nm wavelength range and provides both digital and analog outputs for flexible integration.{IMG_TAG_0}

⭐ Key Features

• IR flame detection (760–1100 nm) 🔎 — optimized sensitivity to the flame spectrum.
• Up to ~80 cm detection for a lighter-sized flame (greater distances for larger flames).
• ~60° detection angle for reliable coverage in front of the sensor.
• Adjustable sensitivity via the onboard blue precision potentiometer.
• Dual outputs: DO (digital switch 0/1) and AO (analog voltage output) for ADC measurements.
• LM393 comparator onboard for clean switching, stable waveform, and > 15 mA drive capability.
• Wide voltage operation: 3.3 V to 5 V for easy use with 3.3 V or 5 V logic systems.
• Mounting holes for simple installation in enclosures or on robots.
• Compact PCB size: 3.2 cm × 1.4 cm.

📐 Technical Specifications

• Wavelength sensitivity: ~760–1100 nm
• Typical detection distance: ~80 cm for a lighter flame (increases with flame size)
• Detection angle: ~60°
• Operating voltage: 3.3 V–5 V
• Outputs: DO (digital 0/1), AO (analog voltage)

• 

🔌 Outputs & Integration

• DO (Digital Output): Switch-type output (0/1) for direct connection to a microcontroller IO pin.
• AO (Analog Output): Proportional analog voltage for precise measurement via an ADC.
• Compatible with Arduino and other microcontroller modules. For Raspberry Pi, use an external ADC to read the analog signal.

🛠️ Usage Guidelines

• The sensor is highly sensitive to flames and also responsive to ordinary light; use shielding and orientation to minimize false triggers.
• Maintain a safe distance to prevent heat damage. A lighter flame is typically detected at ~80 cm; larger flames can be detected from farther away.
• Adjust the precision potentiometer to set sensitivity for your environment and application.
• For higher accuracy, use the AO analog output and perform AD conversion on your microcontroller.

📦 Typical Applications

• Flame alarms and fire detection prototypes
• Robotics (e.g., fire-fighting robot projects)
• Educational labs and hobbyist experiments with Arduino and Raspberry Pi
• General electronics modules and sensor integration projects
