Panel Mount Ultrasonic (Sonar) Ranging Module with UART Output
This sleek-looking 'button' is actually an ultrasonic sensor, ready for panel mount use. Inside is a module that uses high-frequency signals to determine distance to a surface.
Pinout
- 5V1
Red wire #1. Adafruit product page says to connect red wire #1 to 5V for the panel-mount ultrasonic UART sensor.
Type · powerVoltage · 5V per Adafruit product page - GND2
Black wire #2. Adafruit product page says to connect black wire #2 to ground.
Type · groundVoltage · 0V reference - NC3
Wire #3 is intentionally skipped. Adafruit product page says to skip #3.
Type · no connect - UART output4
Wire #4 connects to the host serial input pin; Adafruit says to read data at 9600 baud.
