- class InfraredSensor(port)¶
LEGO® Powered Up Infrared Sensor.
port (Port) – Port to which the sensor is connected.
- distance() int: % ¶
Measures the relative distance between the sensor and an object using infrared light.
Distance ranging from 0% (closest) to 100% (farthest).
- reflection() int: % ¶
Measures the reflection of a surface using an infrared light.
Measured reflection, ranging from 0% (no reflection) to 100% (high reflection).
Measuring distance, object count, and reflection¶
