SmartButton temperature logger

Although it looks big in this photograph, the SmartButton is a miniature temperature logger that's similar in size to a clothes button. It talks to Windows PCs.

Because of its small size and low-cost, you can purchase tens or hundreds of them for multiple-site temperature monitoring. Offered by Saelig Co., SmartButtons are designed for measuring temperature during transit of goods.

The 4g, steel-cased SmartButton measures 17-by-6mm. It's powered by an internal 3V lithium battery. It provides a typical life of 10 years.

SmartButton has a resolution of 8bits and an accuracy of 1C over most of its range. With a clock accuracy of 2-minutes/month from 0 to 45C, measurements can stop when full or re-circulate. SmartButtons have a memory of 2,048 readings, and an operating range of -40C to 85C.

A PC with at least one RS-232 serial port works for SmartButton Reader set-up software, for reading and display purposes. The software is provided with the buttons.

To run it you'll need a PC running a Pentium 75 (at minimum) with 16Mbytes of RAM, a color monitor and a pointing device. The platform must run Windows 95, Windows98, Windows NT, Windows2000, or Windows XP.

A USB port can also be used, with an optional adapter.

As shipped, you get a SmartButton starter pack with one SmartButton, an interface cable, the SmartButton Reader software, and a manual for $79.
