Do ultrasonic sensors work well outside?
You also need to be aware of the effects of temperature on the speed of sound, and how your sensor will attempt to compensate. Each of our ultrasonic sensors is equipped with automatic temperature compensation that keeps your sensor readings accurate as temperature changes. The features works very well, unless the temperature around your sensor is remarkably different than the temperature at the target surface.
When the temperature at the sensor is different than the surface temperature of your target, you have a temperature gradient that changes the speed of sound as it travels. This scenario should be avoided completely to ensure an accurate measurement. When using an ultrasonic sensor outside, protect it from heating up in the sun by keeping it in the shade and away from metal housings or covers. If you are having troubles with temperature gradients, you can turn off automatic temperature compensation and use periodic adjustments to the programming to improve accuracy to an acceptable level.
Will my parameters be saved after a blackout?
Can I adjust the sound beam angle?
As you strengthen both the sound wave and the sensitivity to return signals, you increase the sensor's ability to pick up readings from a wider angle. As you weaken both the sound wave and the sensitivity, you reduce your sensor's ability to pick up return signals from wide angles. You're not actually changing the sound wave spread, but you are changing the power of the sound wave and the amplification of the returning echoes.
