3.2. Rate Gyro (45-2004)
The Rate Gyro is used to detect the rate of rotation. When the Rate Gyro is completely
still, the returned reading is 1.4V which produces a reading of 280° ±2°. With the sensor
idle at 280°, a Counter Clockwise (CCW) rotation will increase the value of the reading
and then return to 280° once movement is stopped. A Clockwise (CW) rotation of the
gyro will cause a decrease in the return value and return to 280° once the sensor is no
longer moving. The readings are accurate to the degree.
