A thread sensor has at least one capacitive sensor that has two electrodes, along which a thread (4) can be moved.

The thread (4) is moved past the electrodes (1, 2; 1 1, 12) of the capacitive thread sensor, resulting in an electric signal (for example waveform C), from which the speed of the thread is determined.

The speed and quality of the thread (4) are evaluated by means of a capacitive thread sensor.

The thread sensor has an optical sensor (13) in addition to the capacitive sensor (1, 2; 1 1, 12), one of the two sensors determining the speed of the thread (4) and the other sensor or both sensors determining the quality of the thread (4).

Said thread monitor comprises a movably mounted thread detector (29) which rests against the thread (15) and moves according to the tension or slack of the thread (15).

The thread delivery device (1) has at least one thread sensor (11, 12), a first and at least one second thread brake (16, 40, 17, 30, 41) in the thread path before the thread delivery wheel (3) and a knot catcher (18).

A transducer element (43) that cooperates with a sensor element (44) is fastened to the thread detector (29).

In one configuration, a sensor lead assembly includes an outer lead body and an inner lead including a sensor such as an electrochemical glucose sensor.

The wireless sensor device comprises a light level sensor and an energy accumulator for providing power to the wireless sensor device.

A wireless sensor reader is provided to interface with a wireless sensor.
