IR Infrared 1 Channel 12V Flame Detection Sensor Module Fire Alarm Sensor Relay Module For Arduino

Features 1 The flame can be detected or the light source with a wavelength ranging from 760 nm to 1100 nm The lighter can test the flame at a distance of 80cm and the larger the flame the farther the test distance2 Detection Angle of about 60 degrees especially sensitive to flame spectrum3 Adjustable sensitivity adjustment of blue digital potentiometer in the figure4 Direct trigger relay of comparator output5 External dimension 50x2 6mm 19mm thick with fixing bolt hole for easy installation6 Output with blue wiring block wiring squareProduct use All kinds of flame fire source detection relay output can be connected to220V large current equipment electrical appliancesProduct parameters Supply voltage 12VDCCurrent greater than 150mALoad 250V 10A aC or 30V 10A DCDirections for use 1 The flame sensor is sensitive to the flame is also responsive to sunlight generally used for fire alarm and other purposes2 By adjusting the potentiometer the intensity of sensor induced flame can be set When the flame exceeds the set threshold the relay pulls and the common end is connected with the constant start3 The three ports of common end normally open and normally closed are equivalent to a double control switch When the relay first has electricity the common end conducts with the normal beginning when there is no eectricity the common end conducts with the normally closed end4 Keep a certain distance between the sensor and the flame to avoid temperature dama
