BASIC FEATURES

SENSORS. BASIC FEATURES. Sensors are mostly electronic devices used to monitor or capture something. . For example, an optical sensor to count the number of items on the treadmill. A complete system that has a sensor and produces an electric output signal is called a transducer. FEATURES.
