Flame Fire Detector Sensor for Arduino (Works with Official Arduino Boards)
Color: Blue PCB panel - Used for temperature detection - The flame sensor is very sensitive to IR wavelength at 760 nm ~ 1100 nm light - AO analog output real-time output voltage signal on the thermal resistance - DO: Digital output when the temperature reaches a certain threshold the output high and low signal threshold adjustable via potentiometer - With 3mm install screw hole - Can be powered by DC 3~3.5V - Comes with connecting cable (20cm)
