Digital Display Module For HC-SR04 Ultrasonic Sensor

The Digital Display Module For HC-SR04 Ultrasonic Sensor shows the distance measured by the HC-SR04 (an ultrasonic sensor that sends sound pulses and measures how long they take to return) directly on an onboard LED (Light Emitting Diode) numeric display. The digital display module board eliminates the need for an Arduino to show readings — plug the HC-SR04 into the module, power it from 5V DC, and the measured distance appears on screen immediately. Valid measurement range runs from 2cm to 400cm.

The ultrasonic sensor display board drives the HC-SR04 trigger and echo cycle internally and converts the echo timing to a centimetre reading. One non-obvious detail — the 400cm maximum range applies in quiet, still air. Strong wind, soft foam surfaces, and objects at sharp angles all reduce effective range because ultrasonic waves scatter instead of bouncing back cleanly. The honest limitation is that at very short distances below 2cm, the module cannot measure reliably due to the sensor’s hardware dead zone.

The hcsr04 display board for arduino also works as a standalone display unit on the bench without any Arduino connected. hobbyists building distance displays and parking sensors use it. To start, connect the HC-SR04 to the module header, power from 5V, and read the display. StemVolt provides fast and reliable delivery of across India with trusted service support.
