Digital Display for HC-SR04 Ultrasonic Distance Measurement Control Board

DESCRIPTION

Digital Display for HC-SR04 Ultrasonic Distance Measurement Control Board adopts 8 bit MCU as the main control chip; it can be applied in distance measurement, testing HC-SR04 ultrasonic module performance. And it supports serial port display and digital tube display.

Features:

•  Onboard STM8S103 high-performance microprocessor
• With digital display
• Data can be output through the serial port
• Effective measuring distance: 3cm - 400cm
• Display unit: cm
• The biggest error: about 1%
• Working voltage: 5V
• Test Board size: 24.2x35.1mm

Specifications:

Interface Description:

• VCC, GND: 5V power interface
• 2.54mm white socket: 5V power supply interface
• TX: module serial port to send foot
• RX: module serial port receive pin
• NRST, SWIN: reserved STM8 program download port

Instructions for use:

•  Measurement distance can be displayed simultaneously through the digital tube and serial port
• Digital display, directly plug in the ultrasonic module, access 5V power supply
• Serial port output: plug in the ultrasonic module, the module's VCC, TX, RX, GND are connected to USB to TTL module 5V, RX, TX, GND, serial communication baud rate 9600, the output format: "D: XXX r n ", Where XXX represents the distance, the unit is CM

Precautions:

• Ranging, the measured object area of not less than 0.5 square meters and should be as flat as possible and slightly stronger reflective ability, otherwise it will affect the test results.
• Effective measuring distance 3cm-400cm, beyond this range may result in data is not allowed or display 000

Package includes:

•  1 x Ultrasonic Distance Measurement Control Board
