Slip21 records temperature or illuminance measurements by wireless module TWE-Lite and shows the listing the latest at first at real-time. It also generates a text file of the latest daily report within 24 hours to an arbitrary address. One can watches its result by browser in WAN/LAN. With a simple bat file, Windows Task Scheduler can upload and update it to your own free site on time automatically. Slip21 on-line manual describes how to do it in my site.
You need 2 TWE-Lite minimum or one TWE-Lite and Monostick. One is End Device and the other is Coordinator. The Coordinator is connected with PC by USB port. The wireless End Device transmits the measurements to the Coordinator. Slip21 always waits the data. Slip21 displays the results for a sampling period of 1 to 60 minutes. If your PC connects WAN (no use of browser), PC's internal calendar clock synchronizes NTP (Network Time Protocol) server.
