Why Do I Need To Let My Ultrasonic Sensor Warm Up Before I Operate It? |
|
Answer» The ultrasonic sensor should not be CONFIGURED or operated until it has had a chance to warm up. When a sensor is first powered up, the individual components heat up and ALSO heat the surrounding SPACE and components. This fluctuation in TEMPERATURE from a cold start to the operating temperature is called "Warm-Up Drift." Until all components have stabilized at the correct operating temperature, the accuracy of your measurements may be AFFECTED.
