Description
ELEGOO HC-SR04 ultrasonic distance sensor module, 5 pack. Five modules for repeatable prototyping: use them across builds, compare sensor positions, or keep spares for testing and replacement.
Non-contact distance sensing with a 40 kHz ultrasonic burst and echo timing. Range is 3-450cm with 0.3cm resolution and an effective angle under 15 degrees. Connect VCC, Trig, Echo, and GND, use a 10 microsecond trigger pulse, and measure the Echo duration.
The HC-SR04 runs on 5V and its Echo output is 5V, so use a voltage divider or level shifting with 3.3V inputs. Keep the module dry. For prototyping rather than calibrated measurement.
Good for robot navigation, object detection, automatic lids, parking alerts, counters, and interactive projects. For a 2 pack with mounting brackets, see the bracket 2-pack listing.
