Detect flames quickly and accurately with this high-performance IR Flame Sensor Module, designed to sense light wavelengths between 760~1100nm. Capable of detecting a lighter flame from up to 80cm and larger flames at even greater distances, this sensor provides reliable flame detection suitable for alarm systems and safety monitoring. Key Features: · Wide Detection Range: Sensitive to flame light within the 760~1100nm wavelength spectrum, ensuring precise identification of fire sources. · Adjustable Sensitivity: Equipped with a blue digital precision potentiometer allowing easy and fine-tuned sensitivity adjustments to suit various environments and detection needs. · Broad Detection Angle: Approximately 60 degrees detection angle for effective wide-area flame monitoring. · Clean and Strong Signal Output: Features comparator output with excellent waveform quality and strong driving capability exceeding 15mA, compatible with microcontroller inputs. · Dual Output Modes: Provides both digital switching output (DO) and analog voltage output (AO) for versatile integration options and enhanced detection accuracy via AD conversion. · Easy Installation: Sensor includes fixed bolt holes for stable and secure mounting in your flame detection setup. · Low Voltage Operation: Works efficiently within a voltage range of 3.3V to 5V, making it suitable for various low-power applications. Specifications: · Working Voltage: 3.3V–5V · Output Format: DO digital switching (TTL signal), AO analog voltage output · Comparator: Wide voltage LM393 · Sensor Length: 4.5 cm (1.77 in) · Weight: 4 g · Detection Angle: Approx. 60 degrees · Flame Light Wavelength: 760–1100 nm Wiring Instructions: · VCC – Connect to 3.3V–5V power supply "+" · GND – Connect to power supply ground "-" · DO – Digital TTL switch signal output · AO – Analog voltage signal output Usage Notes: · The sensor is most responsive to flames but may also respond to ordinary light—optimized for flame alarm applications. · Direct connection of the DO output to microcontroller IO ports is supported for easy integration. · Maintain proper sensor distance from flames to prevent damage. · The analog output combined with AD conversion allows for higher precision flame detection. · When flame or infrared light reaches the set sensitivity threshold, the onboard green indicator LED will light up, and the DO output will switch to a low-level signal (0~0.1 V). When no flame is detected, the LED turns off and DO outputs a high-level voltage (~3 V). Package Includes: · 5 x IR Flame Sensor Module This IR Flame Sensor Module offers reliable flame detection with adjustable sensitivity and multiple output modes, making it an essential component for fire alarm systems, safety monitoring, or DIY projects requiring precise flame sensing.
