Infrared voice greeter

Overview

This product uses the 15w401as chip launched by stc as the main control. It is compact, energy-saving and cost-effective. It can be directly powered by USB. The detection distance can be adjusted through the potentiometer (the silk screen on the PCB is clearly marked). By default, when there is an object When passing from left to right, the welcome device will prompt welcome and the LED light will be on. When the person completely enters, the LED light will go out.
