Psoc Ultrasonic Sensor Jun 2026

: Unlike basic microcontrollers that just trigger a pre-built module, PSoC users often build the entire signal chain inside the chip. For example, a PSoC 1 project uses internal Programmable Gain Amplifiers (PGA) set to maximum gain (48x) to boost the tiny echo signals received from the sensor.

The PSoC measures the duration of this high pulse on the ECHO pin. The distance is then calculated using the speed of sound (approximately 340 m/s or 0.034 cm/µs) and the travel time L=12×T×Ccap L equals one-half cross cap T cross cap C element14 Community psoc ultrasonic sensor

The PSoC ultrasonic sensor works by emitting a high-frequency sound wave (ultrasonic wave) and measuring the time it takes for the wave to bounce back from an object. The sensor consists of a transmitter and a receiver. The transmitter sends out the ultrasonic wave, which travels through the air until it hits an object. The wave then bounces back and is received by the receiver. The distance is then calculated using the speed

: To improve accuracy, some developers suggest using the PSoC’s internal temperature sensor to adjust calculations. Because the speed of sound changes with temperature, the PSoC can dynamically update its math to keep measurements precise.
