Common questions about manuals, registration, and support for this brand.
The HC-SR04 is a 4-pin module. Connect VCC to a 5V power supply, Trig to a trigger pin for sending ultrasonic waves, Echo to receive the pulse, and GND to ground. Consult your microcontroller's wiring guide for specific integration.
The sensor is capable of accurately measuring distances from 2cm up to 400cm with a high-precision resolution of 1cm.
Abnormal readings may occur if the mounting position contains air bubbles or if foreign matter is blocking the sensing port. Also, check to ensure the connection plugs are deeply seated and not oxidized.
