Analogowy, optyczny czujnik odległości SharpSpecification

  • Measurement range is from 2 to 15 cm
  • Supply voltage 4,5 V to 5,5 V
  • Average current consumption 12 mA
  • Refresh frequency: 60 Hz
  • Output: voltage-analog signal
  • Type of case: 27 x 13,2 x 14,2 mm
  • Weight: 2,7 g



The sensor can detect objects at a distance of from 2 to 15 cm. The output is analog signal whose value depends on the distance between the detected object and the sensor. The closer the object is, the voltage at the output will be higher.

The product is compatible with Arduino

The sensor's output should be connected to any analog pin, the measurement is done using the function analogRead(sensorPin);. Example of the project with code can be found on the bildr website



The sensor has three pins ended with the slot, pitch of 1 mm (at the moment, we don't have a compatible plug). The wires can also be soldered directly to pads. Looking at the front of the sensor, from left to right:

  • power- Vcc (voltage from 4.5 to 5.5 V),
  • mass- GND
  • the analog output signal - Vo, the value of which depends on the distance between the sensor and the detected object.
