We have recently completed a tutorial on temperature measurement using thermistors. As you may be aware, we offer thermistors temperature measurement as a standard feature on several of our controllers.
The tutorial covers some of the theory, then goes into the specifics of using thermistors with SPLat. A companion spreadsheet is included, which greatly simplifies the calculations required, plus a "boiler plate" program makes programming easy. Now you can incorporate temperature measurements into your controls at lower cost than ever before.
The tutorial is part of the SPLat Knowledge Base. Click here to access it.
