High performance MEMS based – precise gyro sensor

External trigger for zero-positioning

Excellent in-run bias stability

Continuous-self-diagnosis and vibration-proof

High performance MEMS based – precise gyro sensor GY100S is optimum for rough conditions of construction machinery, heavy equpiment and special vehicles by its continuous-self-diagnosis and vibration-proof abilities. GY100S excels at measuring horizontal rotation degree such as controlling turn-table which application that inclinometer (tilt sensor) cannot measure.

RS232 Protocol

Baudrate (Default) : 115,200bps

Data Format (ASCII)

Count is 7 digits, degree and voltage have 1 decimal point.

Commands

e.g. START+CR+LF

BAUD #	Baudrate setting
RESET	Zero-positioning
START	Measure data continuously.
STOP	Stop measuring.
INTERVAL #	Data out-rate setting
INIT #	Factory reset

# : S/V

Baudrate setting
Default Baudrate is 115,200bps. Baudrate can be set one of 57,600 / 38,400 / 19,200 / 9,600 / 4,800. If send command without S/V, current value will returned.

Data out-rate setting
Default out-rate is 100ms. Out-rate can be set within 10...1,000ms by 10ms of unit. In Angular Velocity mode, out-rate is fixed by 10ms. If send command without S/V, current value will returned.

Wiring Connections

GY100S is wired by MG610331-5 plug (Korea Electric Terminal Co., Ltd.). The plug can be deleted when placed order.
To zero-positioning, short the trigger to V+.

NOTES

Ground connection is recommended in noise occurred environment.
Gyro sensor YAW axis occurs zero-position-drift continuously because it keeps calculating integral calculus for its zero position. This is a characteristic of MEMS gyro sensor.
RS232 protocol may cause delay or crash by internal processing time and other reasons. If commanding is not in real-time, repeat sending the command.
Check wiring connections before use.
12 months warranty is provided after released. Warranty provided only in case of using for designed purpose correctly.
Specifications, design and components can be changed without prior notice to improve its performances.
