IR Flame Sensor Module (4-Pin)

IR Flame Sensor Module (4-Pin)The 4-Pin IR Flame Sensor Module is a high-sensitivity detector engineered to identify the presence of open flames by sensing the specific infrared (IR) light they emit (in the 760nm–1100nm spectrum). This versatile module is an indispensable tool for safety, robotics, and automation projects, offering both simple digital and proportional analog outputs for easy integration with microcontrollers like Arduino, Raspberry Pi, and ESP32. An onboard potentiometer allows users to easily adjust the detection sensitivity.Technical Specifications SpecificationDetailSensor TypeIR Phototransistor (Sensitive to flame-emitted IR)Detection Wavelength760nm – 1100nmOperating Voltage (VCC)3.3V – 5V DCOutput TypeDigital (DO) and Analog (AO)Detection DistanceUp to 100 cm (dependent on flame size)Detection AngleApproximately 60°SensitivityAdjustable via onboard PotentiometerComparator ChipLM393 (Typically)Pin ConfigurationVCC, GND, DO, AO SKU: LKSEN00055 Category: Electronics accessories
