Gyro Sensor(GS-12)

New Sensor

Introduction

• 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.

Sensor Output

New Sensor

Item	MAX	~	MIN
Output Value	510	300	100
Angular Velocity	+300°/s	0°/s	-300°/s
Voltage	2.5 V	1.5V	0.5V

Standard VCC Voltage Value is 5V.

Old Sensor

Item	MAX	~	MIN
Output Value	455	250	45
Angular Velocity	+300°/s	0°/s	-300°/s
Voltage	2.23 V	1.23V	0.23V

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.
