1x 7805 5V Linear regulator module 1
Contrast the World Health Organization UV Index grading standards
Power to USB-port:5V (500mA maximum)
This 8-channel Relay module comes with Optocoupler protection and is an active low relay module which means that the relay will conduct when the input signal falls below 2V and if it is above 2V then the relay is turned off you can also make it an active module by changing the jumper position on the power module
Flame Detection Sensor (IR InfraRed) i/o control 1x 7805 5V Linear regulatorCan detect the flame or the wavelength at 760 nm to 1100 nm range of the light source, the test flame lighters distance of 80cm, the larger the flame, the greater the distance test. With the detection angle of 60 degrees, the flame spectrum particularly sensitive. Sensitivity adjustable. (shown in blue digital potentiometer adjustment) The comparator output signal clean waveform is good, driving ability than 15mA. With a precision potentiometer
