Four Channel
Temperature Monitor & Control Kit
This kit is an extension of our popular CK0110 (DIY Kit 145) Temperature
Logger kit. Like the CK0110 it features 4 temperature inputs using the DS1820 digital
sensor. We have also added 4 relays to provide output control.
Commands for reading temperatures or controlling relays are sent via the
RS232 serial 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 software available for the kit.
This software provides basic thermostat and temperature logging
functions.
Functionally, it's a very nice little
unit -- easy to communicate with (a simple command structure, and simple
data structure), and easy to do hookups. Internally, the relay channels
are independent of the sensor channels. So, in your software you can
set up linkage in any way you like. The CK0110 is constantly pushing
data out the serial line. With the K190, you have to poll the board for
temperature data. The board will work with the same DS1820 and DS18S20
sensors that the CK0110 uses, but can handle the DS18B20 sensor as
well.
