Specification Brand : Agatige BulletPoint1 : 【Infrared Flame Sensor】The ir flame sensor module can detect a flame or the light of 760~ 1100nm wavelength, lighter flame test distance of 80cm, for the greater flame, the farther the distance test. BulletPoint2 : 【Particularly Sensitive】The flame detection module's detection angle is about 60 degrees, particularly sensitive to the flame spectrum. With adjustable accuracy potentiometer for sensitivity adjustment (shown in blue digital potentiometer adjustment). BulletPoint3 : 【Strong Driving Ability】The flame sensor module is in signal clean, good waveform, strong driving ability, more than 15ma. If you need a flame detection module, this product can provide you with good using experience. BulletPoint4 : 【High Quality】The infrared short-circuit detector is made of high quality materials, its excellent strength can make a good performance for a long servicing life, you can use it with confidence. BulletPoint5 : 【Complete Quantity】There are 5pcs smartsense flame module detector in total to satisfy your use and replacement needs, so you don't have to make repeated purchases in a short period of time when you need. ItemName : 5 Pcs Infrared Flame Sensor, IR Flame Module Detector Smartsense Flame Detection Sensor for Detecting Flame and Sensitivity Adjustment ItemPackageQuantity : 1 ItemTypeKeyword : sensor-blocks Manufacturer : Agatige Material : Copper PartNumber : Agatigepsb4yg8wti ProductDescription : Features: Can detect a flame or the light of 760~ 1100nm wavelength, lighter flame test distance of 80cm, for the greater flame, the farther the distance test. Specifications: The working voltage: 3.3V-5V The output format: DO digital switching outputs (0 and 1) and AO analog voltage output Comparator: wide voltage LM393 Length: 4.5cm / 1.77in Weight: 4g Wiring instructions: Product wiring description: VCC: 3.3-5V power supply "+" GND: power supply "-" DO: TTL switch signal output. AO: analog signal output (voltage signal) Instructions for use: 1. the flame sensor is most sensitive to flame, for ordinary light, it is also responsive , generally used as a flame alarm purposes. 2. the output interface can be directly connected to the micro-controller IO port. 3. The sensor must be kept at a distance from the flame to avoid damage to the sensor. lighter flame test distance of 80cm, for the greater flame, the farther the distance test 4. Analog output and the AD conversion process, can achieve higher accuracy 5. When the sensor detects a flame, sunlight, or infrared light, if achieve potentiometer setting threshold, the green indicator light will ON, the DO output low levels (0-0.1 - V), the green light is OFF, the DO output about 3 V high voltage
