Ensure safety and precision in your electronics projects with this high-sensitivity IR Flame Sensor Module. Designed to detect fire sources or light sources within the 760nm to 1100nm wavelength range, this module is essential for DIY fire alarms, safety robots, and smart home monitoring systems.

Equipped with the reliable LM393 wide voltage comparator, it delivers a clean, stable signal with strong driving ability (>15mA). The onboard blue potentiometer allows you to easily adjust the sensitivity to suit your specific environment.

Key Features:

  • High Sensitivity: Detects flame spectrums specifically between 760nm and 1100nm.
  • Wide Detection Angle: Approximately 60 degrees, offering a broad field of view for reliable monitoring.
  • Long Range Detection: Capable of detecting a standard lighter flame at a distance of ~80cm (detection distance increases with flame intensity).
  • Adjustable Sensitivity: Features a precision blue potentiometer to tune the trigger threshold.
  • Digital Output: Provides a clear Digital Switching Output (0 and 1) for easy reading by microcontrollers.
  • Easy Integration: Compatible with 3.3V to 5V systems, perfect for Arduino, Raspberry Pi, and other microcontrollers.

Technical Specifications:

  • Chipset: LM393 Comparator
  • Working Voltage: 3.3V - 5V DC
  • Output Format: Digital Switching Output (DO)
  • PCB Size: 31.0mm x 14.2mm
  • Mounting: Fixed bolt hole for easy installation
  • Connection: VCC (Power), GND (Ground), DO (Digital Output)

Application Examples:

  • Fire alarm systems
  • Firefighting robots
  • Flame detection in industrial equipment

Note: Please maintain a safe distance between the sensor and the actual flame to avoid thermal damage to the sensor components.
