[ Gyro Sensor ]
Product Usage
- Measures angular velocity.
- Calculates which side the robot is tilted or is getting more power.
- Maintains the robot’s balance and can be used for other movement
applications.
Pin Layout Information

[ X Axis Pin ]
- ADC : Outputs the angular velocity into analog signals.
- GND
- VCC ( 5V )
[ Y Axis Pin ]
- VCC ( 5V )
- GND
- ADC : Outputs the angular velocity value into analog signals.

(Standard VCC Voltage Value is 5V.)
- When the angular velocity is 0 (when still), the output value is
approximately 250. When it suddenly turns to one axis, the max value
output is 455 and the minimum 45, showing a 300 ˚/s angular velocity.
Here the mark or sign represents direction.
- Depending on the temperature, there may be 1% difference.
- There may be a difference in value depending on the standard VCC
voltage value and circuit noise. Thus, we recommend to average several
values before use.
(When sampling, the robot must not
be moving.)
- You can READ the value using the User’s
Device Parameter in RoboPlus Task.

- You may sample it out like below. It reads 10 values per 0.1 sec
and makes an average. This value can be used as the standard value.
