#163411 - General problem with semiconductors. Responding to: ???'s previous message |
Semiconductor temperature sensors are usually quite non-linear (same goes for thermocouples). It kind of comes with the territory. The way around this is linearizing them in software (Steinhart&Hart equation for thermistors, etc). A '51 should be able to handle that.
As far as I'm aware, only "metallic" temperature sensors are linear (for example PT100 sensors, and yes, the PT stands for platinum). |
