Digital Display for HC-SR04 Ultrasonic Sensor
The Digital Display for HC-SR04 Ultrasonic Sensor utilizes a 8 bit MCU as its main control chip, making it applicable for both distance measurement and testing the performance of HC-SR04 ultrasonic modules. Additionally, it offers support for both serial port and digital tube display options.
Key elements of Digital Display for HC-SR04 Ultrasonic Sensor:
- Equipped with a high-performing microprocessor, the STM8S103 onboard feature ensures optimal functioning.
- Featuring a digital tube display.
- Data output from a serial port.
- Measurement distance must be between 3-400cm to be considered valid.
- Display Unit: Centimeters
- The maximum error is 5 volts.
- The dimensions of the board are 36 x 25 x 12 mm.
- The VCC and GND both serve as a 5V power interface.
- The White Socket with a diameter of 2.54mm serves as the 5V power interface.
- Digital Display for HC-SR04 Ultrasonic Sensor serial port is responsible for transmitting data via its pin.
- RX: pin for receiving serial data on the module’s port.
- The STM8 program download port is pre-set on NRST and SWIN.
Employing an introduction:
- The measurement distance can be easily read through the digital tube or a serial port. For digital tube display, simply plug in the ultrasonic module and connect it to a 5V power source.
- To connect the ultrasonic module, simply plug it into the Serial Port. Make sure to connect the VCC, TX, RX, and GND pins of the USB to TTL module to the corresponding 5V, RX, TX, and GND pins. The baud rate for serial port communication is 9600 and the output format is “D:XXXrn”, where XXX indicates distance in centimeters.
Please be advised:
- When determining distance, ensure that the object being measured has a minimum area of 0.5 square meters, is smooth, and has strong reflectivity. Failure to meet these criteria may impact the accuracy of the test results.
- The acceptable measurement distance falls between 3-400cm. Any distance beyond this range may result in inaccurate data or a display of 000.
