Infrared

class devices.Infrared(ev3handle, layer=1, portnum=1, inputmode='proximity')

The class to represent the EV3 infrared sensor.

Set up an infrared sensor on port number 4

>>> from pyev3.brick import LegoEV3
>>> from pyev3.devices import Infrared
>>> myev3 = LegoEV3(commtype='usb')
>>> mysensor = Infrared(myev3, portnum=4, inputmode='remote')

Parameters

• ev3handle (object) – LegoEV3 instance representing the EV3 brick.

• layer (int) – The layer of the brick 1 or 2 in a daisy-chain configuration.

• portnum (int) – The brick input port connected to the sensor. Possible values are 1, 2, 3, or 4.

• inputmode (str) –

  • 'proximity' detect proximity to an object

  • 'seeker' searches beacon (requires channel 1 and beacon on)

  • 'remote' takes remote control input

display_info()

Displays a summary with the sensor information.

property inputmode

Contains the sensor input mode. Use this to change the mode on the fly (read/write).

property output
