The Digital Display Module for HC-SR04 Ultrasonic Sensor is a compact 35mm x 25mm plug-and-play digital display module board that connects directly to an HC-SR04 ultrasonic sensor and shows the measured distance from 2cm to 400cm on a bright LED numeric display without requiring an Arduino, microcontroller, or any programming. The ultrasonic sensor display board operates at 5V DC and handles all the trigger-echo timing, distance calculation, and display driving internally — making it a standalone distance meter for lab demonstrations, teaching setups, and prototype builds where a quick visual readout is needed without code development.
The hcsr04 display board connects to the HC-SR04 using a standard four-wire VCC-GND-Trig-Echo interface, and the digital display board updates the LED reading in real time as the measured distance changes. The hcsr04 display board for arduino builds can also be used alongside Arduino — the Arduino connects to the HC-SR04 separately, while this display board provides a simultaneous visual readout on the same sensor without interfering with the Arduino’s Trig-Echo measurement cycle, since both can share the sensor output.
One practical trade-off: the HC-SR04 sensor itself is not included with this hcsr04 display board price — the display module is designed as an add-on for an existing HC-SR04, and the sensor must be purchased separately. StemVolt provide this module is well-suited for makers adding instant distance readouts to HC-SR04 builds and practical embedded distance display electronics projects.
