Talk:SDI-12
Frankly it's a poxy protocol that should be deprecated.... Slow, difficult to implement in modern uarts coz it uses the break sequence... BUT it's human readable... (fire up the old TRS-80 to read the data!). --PeterMarkSmith 07:18, 28 November 2006 (UTC)
More expensive?
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.
