Feature:1. DETECTION FUNCTION: Can detect flame or light source with wavelength from 760nm to 1100nm. The flame distance of the lighter is 80cm. The larger the flame, the further the test distance, detection angle is about 60 degrees, which is particularly sensitive to the flame spectrum2. STRONG DRIVE: The flame sensor module adopts comparator output, the signal is clean, the waveform is good, the driving ability is strong, more than 15mA3. SENSITIVITY ADJUSTMENT: This flame sensor module has a potentiometer to adjust the sensitivity and uses a wide voltage LM393 comparator4. BASIC SPECIFICATIONS: The working voltage of the flame sensor module is 3.3V-5V, and the output form is digital switch output (0 and 1)5. CONVENIENT OPERATION: This flame sensor module comes with fixing bolts holes, which for easy installation, is simple to use and durableSpecification:Item Type: IR Flame Sensor ModuleMaterial: ABSWorking Voltage: 3.3V-5VOutput Form: Digital Switch Output (0 and 1)Small PCB Size: Approx. 3.2 x 1.7cm / 1.26 x 0.67inWith fixing bolts holes for easy installationUsing a wide voltage LM393 comparator Package List:1 x Flame Sensor ModuleNote:Flame sensors are most sensitive to flames and also respond to ordinary light, is often used for fire alarms and other purposes
