Analog ultrasonic sensor (US-016)
US-016
An ultrasonic sensor that gives the distance as a voltage: read it with an analog pin.
2Use it
| Pin or leg | What it is for |
|---|---|
| VCC | + 5 V |
| GND | GND |
| Out | to an analog pin: the voltage grows with the distance |
| Range | sets the far end: about 1 m or 3 m |
- VCC to 5 V, GND to GND, Out to an analog pin (A0 on the Arduino).
- Leave Range as it is unless you need the far end.
Good to know: Its output can reach 5 V: into a Micro:bit pin only through a divider.
