The sensor emits eight bursts of 40 kHz ultrasonic sound.
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. psoc ultrasonic sensor
