Sharp IR Sensor — 0A41SK

4–30cm Infrared IR Distance Measuring Sensor —Ardu_Serie # 82

The Sharp distance sensors are a popular choice for many projects that require accurate distance measurements.

The lower minimum detection distance makes this sensor great for detecting very close objects.

The distance is indicated by an analog voltage, making this sensor very easy to use.

How it Works:

IR Sensors work by using a specific light sensor to detect a select light wavelength in the Infra-Red (IR) spectrum. By using an LED which produces light at the same wavelength as what the sensor is looking for, you can look at the intensity of the received light.

Installing SharpIR library

Fig 2. You can download this LIB zip from guillaume-rico/SharpIR repo :)

In the fig 2 you can choose which one is your IRSharp sensor model.

I have two of them:
