WebFor an absolute sensor, as the sensor increases its altitude, it will approach absolute zero, as expected. However, this can become problematic for a barometric range sensor as the reading will no longer be ~14.5 psi when vented to atmosphere. Instead, the local barometric pressure may read ~12.0 psi. However, this is not the case. http://www.yournwinspector.com/your-northwest-inspector/garage-door-safety-sensors-what-height inat box windows 11

Understanding Absolute Pressure Sensors Technical Note

WebA linear device determines absolute travel across a defined path (line, arc, and so forth) with an inherent zero-field point and a range of linear field response relative to travel. The travel range can be increased by evenly spacing multiple sensors without overlapping their linear regions. Straight Linear Travel Output Response From Each Sensor WebI am looking for a way to determine vehicle height measured from the side.
