Among the changes made by Apple to its laptops over the years, the transition from a Hall sensor-based sleep sensor to an angle sensor that determines when the lid is closed is a decidedly unpopular ...

Sometimes we need a non-contact liquid level sensor. There are several ways to build that, but the easiest is to try an optical liquid level sensor. You may already have an idea in mind since you are ...

Smartphones rely on multiple sensors—such as the accelerometer, gyroscope, compass, and proximity sensor—to power everyday features. From screen rotation and navigation apps to motion tracking and ...

Sensor manufacturers typically calibrate the devices in the factory to achieve highly accurate outputs, but all sensors experience some offset error once they are in ...

O(p2): The quadratic contribution in pressure refers to the nonlinearity error of the reading which is typically in the range of 0.3% full-scale output. The offset ...

Calibration is necessary before the installation of an AC- operated linear position sensor to ensure accuracy. Calibration corrects any slight variances between sensors, helping to improve ...
