A sensor is a transducer that converts a physical, biological or chemical parameter into a electrical signal, for example: temperature, pressure, flow, or vibration sensor. Sensors also measure some physical parameter and return digital data representing that parameter to an NCAP.
A sensor can also describe itself to the network, making it easier for automatic system configuration. It does this by the use of TEDs.The TEDs can be uploaded to the system upon power up or upon request. It also serves as documentation.
Takes a new sample with each trigger.
Behaves like a sensor, but makes the data acquired on the previous trigger available for immediate reading.
Acquires a sequence of measurements without missing a sample.
Keeps the most recent readings in its buffer so that it is always available to be read immediately after a trigger.
Armed by the trigger and responds with an acknowledge signal when the event is detected.
