Product description
This kit is an 'extension' of our popular K145 Temperature Logger kit. Like K145 it features four (4) temperature inputs using the DS1820 digital sensor. We have also added four (4) relays to provide output control. Commands for reading temperatures or controlling relays are sent via the RS232 interface using simple text strings. The kit can be controlled by a simple terminal or communications program (such as Hyperterminal) or via
the free Windows application
