Introduction

This laser-guide kit is used for object detections with laser, the kits includes an laser emitter, laser modulator, laser receiver and a lens, the laser modulator modulates the laser, which emitters from laser emitter, to180Khz, when the laser echoes back, the laser receiver receives the signal, and reports the MCU. With the advantage of laser, this kit can detects object white-color or black-color in a range of more than 1250px.

Technical data

Suggestion: add a potentiometer in L11 and R15;

The CAP C11(47uF or 1uF) is necessary;

When black object detected, the IN signal is “1”,LED(L12)off, and vice versa;
