HC-SR04 Ultrasonic Distance Measurement Module

Features :
Onboard N76E0033 high-performance microprocessor.
7 Segment LED display.
Serial port data output.
Valid Measurement Distance: 3-400cm.
Display Unit: cm.
Board Size: 39mm x 39mm.
VCC, GND: 5V power interface.
2.54mm White Socket: 5V power interface.
TX: module serial port transmits pin.

Using Introduction:
1. The measurement distance can be displayed via the 7 Segment LED display and serial port.
7 Segment LED display: directly plug in the ultrasonic module, connect 5V power.
2. Serial Port: plug-in ultrasonic module, VCC, TX, RX, GND respectively connects 5V, RX, TX, GND of USB to TTL module; serial port communication baud rate 9600, output format “D:XXX\r\n”; XXX represents distance, unit is cm.

Notice:
1. When measuring the distance, the area of a measured object should be no less than 0.5 square meters, and it should be smooth and has strong reflectivity, or it will affect the test result.
2. Valid Measurement Distance: 3-400cm; if longer than this range, it will lead to incorrect data or 000 display.

This Package does not include the HC-SR04 ultrasonic sensor and will need to buy it separately
