Traditional ultrasonic distance sensors (e.g., HC-SR04) typically require a dedicated microcontroller (MCU) to trigger the sensor and measure the echo pulse width. However, PSoC (Programmable System-on-Chip) devices from Infineon (formerly Cypress) offer a unique, integrated alternative. By combining configurable analog blocks, digital logic, and an ARM Cortex-M CPU, a PSoC can implement an ultrasonic sensor interface with minimal external components and advanced signal processing. // Measure time for wave to bounce back

| Feature | Benefit | |---------|---------| | | The PSoC integrates timing, logic, and analog conditioning, reducing BOM cost and PCB space. | | Programmable gain & filtering | Adjust sensitivity for different ranges or surface reflectivity without hardware changes. | | Low power | PSoC can enter deep-sleep between measurements and wake using a watchdog timer or GPIO. | | Multi-sensor support | Use the same PSoC to sequence multiple transmitter-receiver pairs for spatial mapping. | | I2C/SPI/UART ready | Directly interface with a host system without additional glue logic. | #include &lt;project
