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
