TIL 1374: Motion Detector Troubleshooting and FAQs

- 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.

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