Comparator chip LM393. Detects a flame or a light source of a wavelength in the range of 760nm-1100 nm, Detection angle about 60 degrees, it is sensitive to the flame spectrum. Accuracy adjustable Operating voltage 3.3V-5V Output * DO digital switch outputs (0 and 1) * AO Analog voltage output * power indicator and digital switch output indicator * With a mounting screw hole * PCB size: 3.1cm x 1.5cm
Note: Please keep a distance with flame, high temperature maybe burn out the sensor module. Interface Description (4-wire) 1 VCC: 3.3V-5V voltage 2 GND: GND 3 DO: board digital output interface (0 and 1) 4 AO: board Analog output interface Support our scratch driver software, can be easy use in scratch

ADC can use MCP3002, ADS1015, MCP3424 , use GPIO 4 for Digital input
1.broadcast "3002init" & "g4in" GPIO 4 as input 2.in Sensing --> Slider , you will see the "GPIO-4" & "M3002-AD0" & "M3002AD1" in the list
