Troubleshooting
The LED on the Go!Motion is a useful troubleshooting tool. When working correctly, the LED on the Go!Motion is green. If your LED is not green, see:
     TIL 2113: The LED on my Go! device or LabQuest Mini is not green. What does that mean?

TIL 5: Why am I getting Motion Detector readings that are noisy or max out at a certain distance?
TIL 459: What don't I get a freefall acceleration value of 9.8 m/s^2 when using a motion detector?
TIL 1009: Why are LabPro Motion Detector distances in Logger Pro sometimes offset by 1 meter?
TIL 1205: My Motion Detector is not collecting data with DataMate and LabPro.
TIL 1914: My motion detector still reads 0.004 m after zeroing.
TIL 2053: How do I improve the results from a Motion Detector with an air track?

SPECIFICATIONS

- order code: GO-MOT
- ultrasound frequency: 50 kHz
- resolution: 1 mm
- accuracy: 2 mm
- range: MD-BTD - 0.15 m to 6 m
- speed of ultrasound used to calculate distance: 343 m/s *
- power: 51 mA while running

*Adjusting the "temperature" setting in Logger Pro changes this value. Speed increases with temperature. We apply a linear correction such that a 1°C change of temperature is equal to 60 cm/s change of speed of sound. The Go! Motion is more sophisticated because only it has a built-in temperature sensor and applies the correction automatically.

CALIBRATION

- Air temperature corrections are possible only in Logger Pro and Logger Lite in the Sensors dialog.
