The temperature sensor kit can be connected directly to a PC via a COM port. No power supply is needed. The temperature of 4 sensors can be measured simultaneously en read out via a terminal program (Windows 95/98, Windows NT/2000/XP), or the data can processed by yourself using a simple program or script. The kit is based on a low cost 8 pin PIC processor and for convenience a flowchart of the processor software is included. The SMTAS04 USB is also available.
