Sensors Light Sensor Detects the surrounding light intensity (not color) between 0 – 100%. The Light Sensor can generate it’s own light (Ideal for line following). To allow this to happen the “Generate light” box in the Light sensor block configuration panel needs to be ticked.
Sensors Ultrasonic Sensor Allows a robot to detect the distance to objects and walls. It has a range of 0 – 255cm. It works by sending out and receiving sound waves. Similar to the echo sounding used by bats. Harder objects will return more accurate readings than softer objects which can absorb the sound waves.
Sensors Sound Sensor The Sound Sensor gives readings of Sound Pressure in Decibels (dB) or Adjusted Decibels (dBA). For the Mindstorms NXT, the readings are presented as Percentages (%). 0-5% Silence/Whispering. 5-10% Normal classroom noise. 10-25% Talking to sensor as a microphone. 25-100% Loud noise/music. Note: dB – Sounds beyond our hearing range dBA – adjusted to our hearing range
Sensors Touch Sensor The Touch Sensor can respond to being pressed, released or bumped. As shown on the Touch sensor block configuration panel Extra pieces can be added to the front of the Touch sensor to make a bigger bumper.
