• A sensor acquires a physical quantity and converts it into a signal suitable for processing (e.g. optical, electrical, mechanical) • Nowadays common sensors convert measurement of physical phenomena into an electrical signal • Active element of a sensor is called a transducer This optical liquid sensor was originally designed for a small-scale industrial application, but will also find many hobby/domestic applications. Note that the circuit is designed with simplicity as the top priority. The supply voltage of 12V is usually suitable for industrial use, and the sensor connections are protected against polarity reversal. Reflective Optical Sensor with Transistor Output. The TCRT5000 is a reflective sensor which includes an infrared emitter and phototransistor in a leaded package which blocks visible light. The "blue" LED is the IR emitter. Gas Sensor Tutorial. Stark produces and repairs electro-optic sensors that are used on airborne, ground and maritime vehicles, and for perimeter observation.Stark's variety of sensor systems are able to support day or night/thermal observation, surveillance, tracking, ranging and targeting. apps.dtic.mil In this course, you will develop the techniques of modeling and simulation for modern electro-optical and infrared (EO/IR) systems. Learn modeling techniques to sensor systems design, analysis, test and evaluation, and performance assessment. Plus, cover basic EO/IR physics principles, fundamental modeling and simulation approaches, methods of modeling and simulating A Shaft Speed Switch is a device that monitors rotating shafts that are critical to the proper operation of
