Analog Distance Sensor

Sharp 4-30 cm Analog Distance Sensor

Summary

• This sensor detects reflective objects that are 4-30 cm away.
• The sensor outputs a voltage from approximately 0-3.3 volts which you can read into a microcontroller

---

Wiring

• This sensor has three cables coming out of it: red-power, black-ground and white-signal.
• Wire the power cable to the Arduino's 5V, the ground to the Arduino's ground
  • Plug the signal cable into any of the Arduino's analog input pins (A0-A5 for the Arduino UNO) with a small pull-down resistor

Programming

• Looking at the graph on page 4 in the datasheet for the sensor
