Ev3dev sensors

Note

This class is only available on EV3.

EV3 MicroPython is built on top of ev3dev, which means that a sensor may be supported even if it is not listed in this documentation. If so, you can use it with the Ev3devSensor class. This is easier and faster than using the custom device classes given above.

To check whether you can use the Ev3devSensor class:

  • Plug the sensor into your EV3 Brick.
  • Go to the main menu of the EV3 Brick.
  • Select Device Browser and then Sensors.
  • If your sensor shows up, you can use it.

Now select your sensor from the menu and choose set mode. This shows all available modes for this sensor. You can use these mode names as the mode setting below.

To learn more about compatible devices and what each mode does, visit the ev3dev sensors page.

Example: Reading values with the Ev3devSensor class

In this example we use the LEGO MINDSTORMS EV3 Color Sensor with the raw RGB mode. This gives uncalibrated red, green, and blue reflection values.

Example: Extending the Ev3devSensor class

This example shows how to extend the Ev3devSensor class by accessing additional features found in the Linux system folder for this device.
