Flame Sensor 5-Channel Module

Five Channel Flame Sensor Module – Technical Specifications

Description:

The Five Channel Flame Sensor Module is designed for multi-directional flame detection, using five independent infrared sensors positioned at 30° intervals. This arrangement provides a wide detection angle of more than 120°, making it ideal for fire detection and robot navigation applications. It is sensitive to short-wave near-infrared (SW-NIR) light in the range of approximately 700 nm to 1100 nm, with typical detection distances up to 80 cm for a lighter flame.

• Detection Angle: > 120° with five sensors at 30° spacing
• Wavelength Range: ~700 nm – 1100 nm (SW-NIR)
• Detection Distance: Up to ~80 cm for lighter flame (longer for larger flames)
• Operating Voltage: 3.3 V – 9 V DC
• Outputs:
  • 5 × analog outputs (one per sensor)
  • 5 × digital outputs (one per sensor)
• Sensitivity Adjustment: Onboard potentiometer for digital and analog tuning
• Indicators: 5 × channel LEDs + 1 × power LED
• Resistor Tolerance: 1% precision resistors for improved accuracy
• Construction: SMT components for durability and stable performance
• Mounting: 3 × M3 mounting holes
• Board Diameter: ~40 mm (PCB only) / ~55–57 mm including sensors
• Height: ~15 mm
• Weight: ~8 g

Key Features:

• Wide-angle flame detection (> 120°)
