Usage:Apply for flames, fire source detection. The module can detect flame or with wavelength in the range of 760 nm to 1100 nm. The flame distance of the lighter is 80 cm. The larger the flame, the farther the test distance is.Used for fire alarms, etc The detection angle of the module is about 60 degrees, which is particularly sensitive to the flame spectrum with adjustable precision potentiometer to adjust sensitivity(blue digital potentiometer adjustment in the figure) The comparator output, the signal is clean, the waveform is good, the driving ability is strong, more than 15mA Working voltage 3.3V-5V. Output form: DO digital switch output (0 and 1) and AO analog voltage output.Use wide voltage LM393 comparator Note:Keep the sensor and flame at a certain distance to avoid high temperature damage to the sensor.The small board output interface can be directly connected to the IO port of the microcontroller.Small board analog output mode and AD conversion processing for higher precision colour:Black and blue Material:Plastic and metal size:3.2x1.4cm Package Contents: 10 x IR Flame Detection Sensor Modules Module instructions: 1. The flame sensor is most sensitive to flame and is also reactive to ordinary light. It is generally used for flame alarms and other purposes. 2, the small board output interface can be directly connected to the IO port of the microcontroller 3. The sensor and the flame should be at a certain distance to avoid damage to the sensor at high temperature. The flame distance of the lighter is 80cm. The larger the flame, the farther the test distance is. 4, small board analog output mode and AD conversion processing, can achieve higher precision Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is 1-3cm.
