Introduction to sensors

Touch sensor
The Touch Sensor gives your robot a sense of touch.
The Touch Sensor detects when it is being pressed by something and when it is released again.
You can use the Touch Sensor to make your robot pick up things: a robotic arm equipped with a Touch Sensor lets the robot know whether or not there is something in its arm to grab.
You can use a Touch Sensor to make your robot act on a command.
Light Sensor
The Light Sensor is one of the two sensors that gives your robot vision
The Light Sensor enables your robot to distinguish between light and dark. It can read the light intensity in a room and measure the light intensity of coloured surfaces.
You can make a burglar alarm robot: when an intruder turns on the light in your room, the robot can react to defend your property.
You can make a line-following robot or a robot that can sort things by colour.
Ultrasonic Sensor
The Ultrasonic Sensor enables your robot to see and detect objects.
You can use it to make your robot avoid obstacles, sense and measure distance and detect movement.
The Ultrasonic Sensor measures distance in centimeters and in inches.It is able to measure distances from 0 to 255 centimeters with a precision of +/- 3 cm.
The Ultrasonic Sensor uses the same scientific principle as bats:it measures distance by calculating the time it takes for a sound wave to hit an object and return – just like an echo.
