Working voltage: 3~5V

PCB size: 92×60mm

Product weight: 17g

Measures:

1 List of components and comparing the number and properties of identity components

2 check the resistance of all resistors with a multimeter

3 Confirm the component polarity and mounting direction on the board in advance.

About debugging:

The machine is powered by 3 to 5V DC power. Turn on the power and turn on the power switch. At this time, the buzzer will sound.

When the LED is bright, slowly adjust the VR1 potentiometer so that the buzzer does not ring. Adjust the potentiometer to affect the detection distance. The detection distance of the machine is less than 6cm, which is affected by the size of the detected object and the environment.

Tools required for assembly testing:

Electric iron, solder wire, universal meter, tweezers, diagonal pliers, charging treasure
