Ujjdwiurgh 51 Microcontroller Designed Reversing Radars Alarm DIY Distance Measuring Loose Parts Measuring Instrument

Integrated Design: Consists of a special circuit board, microcontroller, digital tube, high-precise distance measuring module, buzzer, and other components, highly integrated. 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. 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. 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.
