Why do I need to let my ultrasonic sensor warm up before I operate it?

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.
