A sensor is a special electronic part that can detect changes such as movement,
light, sound, direction or temperature. It collects information and sends it to the

robot’s brain or microcontroller, which decides what to do next.
Robots cannot see or hear like humans do, but they use sensors to understand the

world around them. Sensors can detect movement, direction, temperature, light
and more.

Think about your smartphone. It turns
the screen automatically when you tilt

it or counts your steps when you walk.
This happens because of sensors. The

Micro:bit also has built-in sensors that
allow it to do similar things.

MOTION SENSOR

The Micro:bit can sense movement through its motion
sensor, also known as the accelerometer.

It detects when you shake, tilt or turn the board in
different directions. which means it can detect changes

in speed and direction. When you move or shake the Motion
Micro:bit, the accelerometer reacts to those changes. Sensor

For example, when you shake the Micro:bit, the accelerometer detects the
sudden change in the board's position. It quickly measures how much the Micro:bit

has moved.

Similarly, if you tilt the Micro:bit (left, right, up or down), the accelerometer can tell
in which direction you’ve moved the device.

It measures the angle of tilt and sends this information to the Micro:bit’s brain
(the microcontroller), which can then trigger an action.

These movement signals are sent as data to the Micro:bit, which can then use

the data to perform different tasks. For example, shaking the board might make
the Micro:bit show a smiley face or tilting it left could make an arrow appear on

the screen pointing left.
You can use these signals to create interactive projects, such as games where

shaking the Micro:bit triggers an event, like rolling a dice or jumping over an obstacle.
You can also create timers where tilting the Micro:bit counts down the seconds.
