HC-SR04

by Universal Microelectronics

HC-SR04 is a four-pin ultrasonic ranging module that combines an acoustic transmitter and receiver for non-contact distance sensing. Designers often use it in robotics, presence detection, and prototype measurement systems, with trigger and echo connections represented at the schematic level. This library entry supplies a 4-pin symbol and the TH_HC-SR04V through-hole footprint with 4 pads; a 3D model is not available for this record. Its conversion has been used by 4 ProtoFlow engineers in real designs, so the imported symbol and footprint have passed through practical editor use. The HC-SR04 files can be opened directly in ProtoFlow for schematic placement and board layout.
