More expensive?
[edit]The standard document itself contains a section titled "Advantages" which lists, among other benefits:
- Sensors can use low cost EEPROMs (electrically erasable programmable read only memory) for calibration coefficients and other information instead of internal trimming operations.
- The use of a standard serial interface eliminates significant complexity in the design of data recorders.
These wouldn't have been thrown in as an afterthought. It seems wholly incorrect to assert that SDI-12 devices "tend to be more expensive" based on the unfounded assumption that "extra components and chips" result in a higher overall price.
