The sensor is a device or component that is used to transform a non-electrical quantities (physics and chemistry) to the amount of electricity that can be analyzed with a particular electrical circuit. There are some terms that need to be considered, namely the mistake (error), accuracy (accuracy), sensitivity (sensitivity), repeabilitas (repeability), hysteresis (hysteresis), linearity (linearity). The term errors (error) is ...
