I had to look up the definition of "NTC sensor": "An NTC (Negative Temperature Coefficient) sensor is a highly accurate, low-cost resistor made of sintered ceramic or metal oxides that decreases in electrical resistance as its temperature increases. Primarily used for temperature measurement, control and compensation, these solid-state sensors (e.g., 10kΩ epoxy, bead, glass, SMD) are widely applied in automotive (coolant/intake air), HVAC and consumer electronics to monitor or react to thermal changes."
Then I had to look up "sintered": "produced by or subjected to sintering (the process of coalescing a powdered material into a solid or porous mass by means of heating without liquefaction)."
And I had to look up "SMD": "SMD (surface mount device) sensors are the solution for temperature measurement applications where the sensor needs to be incorporated onto a printed circuit board (PCB)."
I also learned that Oura is pronounced "aura." I are so much more smarterer now!
