Drag to rotate; pinch to zoom. With the view focused: arrow keys rotate, + / − zoom, 1–3 choose a layer, Home resets rotation and zoom. Step advances to the next layer; Reset returns to the case and default view. Layer buttons select a view directly. The page does not move on its own.
The outer coating covers the thermistor body, with two leads extending below it.
Teaching view: The grey coating and blue dot mark the outside of the thermistor. Peel away the coating to see the body whose resistance falls as it warms.

A fixed resistor and the thermistor form a voltage divider. [Practitioner: The Beta Equation, Worked]
The divider voltage is used to infer thermistor resistance. [Practitioner: The Beta Equation, Worked]
Teaching view: The two leads connect the thermistor to an external voltage divider. A fixed resistor completes the divider, turning the changing thermistor resistance into a voltage to measure.
A bead-style NTC thermistor is a resistive body on two leads. [Cheap Nonlinear Thermistors]
As an NTC thermistor warms, its resistance falls along a curve rather than a straight line. [Cheap Nonlinear Thermistors]
Teaching view: The tan body represents a temperature-sensitive semiconductor connected to two silver leads. As it warms, its resistance falls. The voltage divider turns this change into a voltage, which the readout uses to calculate temperature.
Explode separates the proposed layers; X-ray makes the case translucent. These are teaching views. No commercial sensor construction or wiring is specified.
