DIY Distance Measuring Loose Parts Based on 51 Microcontroller Designe

DIY Distance Measuring Loose Parts Based on 51 Microcontroller Designe Beschreibung

Integrated Design: Consists of a special circuit board, STC microcontroller, digital tube, high-precise distance measuring module, buzzer, and other components, highly integrated.
Easy to Use: Simple operation, no programming required, can be used by simply plugging into the powersupply, no professional knowledge required.
High-precise Distance Measurement: -SR04 high-precise module, built-in high-accurate distance measurement probe, stable distance measurement, measuring distance up to 4 meters, to meet most of the distance measurement needs.
Real-time Display: Transistor-driven digital tube, the digital tube real-time display of the current distance to the obstacle, so that the user can real-time grasp the distance information.
Alarm Function: Buzzer alarm function, when the distance is less than the alarm distance, an alarm sound is issued to remind the user to pay attention to increase safety. It can be used as the reverse radars of the car, and the alarm distance can be set by the buttons, applicable to a variety of scenarios.
