an excellent summary of the most common temperature sensing technologies.
For many of these, we have used piecewise linear compensation schemes to get high accuracy results wihout having to store a lot of data. However a lookup table is also an option. A 10 bit ADC requires 1024 entries to cover the entire range. Storage versus execution power and power consumption is the usual tradeoff.
Temperature sensing, both ambient and specific monitoring points, is one of the most common data logging parameters we cover in our industrial telemetry products and low cost electronics pricing targets can be routinely achieved with high accuracy through the use of careful analogue electronics design and software compensation schemes.
Thanks again for publishign this excellent information summary.
