Ultrasonic Distance Sensor - 3V or 5V - HC-SR04 compatible
HC-SR04-compatible ultrasonic distance sensor with trigger/echo interface, operating at 3 V or 5 V for 2–450 cm range. Drop-in replacement for standard HC-SR04 in 3.3 V microcontroller systems without level shifting.
Pinout
- Vcc
Power pin for the HC-SR04-compatible ultrasonic sensor; Adafruit Learn says this sensor requires 5V power for best results.
Type · powerVoltage · 5V power for best results - Trig
Trigger input; Adafruit Learn says setting Trig high for 10µs initiates an ultrasonic burst.
Type · signalVoltage · 3V or 5V signal - Echo
Return signal; Adafruit Learn says Echo goes high after the burst and stays high until the echo is received, so pulse width is used to compute distance.
