51 Microcomputer Ultrasonic Rangefinder Module Reverse Radar Alarm HC-SR04 Kit
Description
Product Feature:
1. Use high-quality materials with guaranteed quality
2. The ultrasonic distance measuring instrument of single chip microcomputer is designed with single chip microcomputer+HC-SR04 ultrasonic sensor+Nixie tube+button+buzzer
3. The alarm distance can be set. After pressing the setting button, you can press the plus or minus keys to modify the alarm distance, and it has the function of saving after power failure
When the measured distance is less than the set distance, the buzzer will alarm
5. The characteristics of this design: wide measurement range, stability, and very convenient operation. It can be used when powered on
Parameters:
Key description: Starting from the first one on the left, the - key,+key, and setting key
Model of microcontroller: STC89C52
Module measurement range: 5cm --4m
This design can be used as a reverse radar for automobiles
Input voltage: DC4.5-5.5V
1. Double sided wiring, solder pads sprayed with tin and treated with increased tin process, can withstand multiple repeated disassembly and soldering, and are not easy to fall off;
2. It is not easy to undergo self bending (referring to bending caused by non manual conditions), and poor boards will bend over time and environmental changes.
3. More stable and reliable impedance;
be careful:
The power supply design adopts USB to DC005 power supply, as sometimes there is no USB port. For convenience in power supply, we provide a 3-section battery box that can be soldered on according to our own needs.
