Instruction:
"+" is the positive power connection, "-" is the negative connection. Do not connect upside down, otherwise the chip burns through.
There is an LED stream display on the P mark on the circuit board. It shines when the module works normally.
Turn the blue potentiometer in or against clockwise to increase or reduce the detection threshold.
If you turn the potentiometer clockwise so far that the LED display marked with "S" shines, this means that the test threshold has been exceeded.
