Pittsford, New YorkAlthough 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 4-gram steel-cased SmartButton is 17-mm in diameter x 6-mm (0.68 x 0.24-in.) thick. It's powered by an internal 3-V lithium battery. It provides a typical life of 10 years.
SmartButton has a resolution of 8-bits and an accuracy of ±1°C over most of its range. With a clock accuracy of ±2-minutes/month from 0°C to 45°C (32°F to 113°F) measurements can stop when full or re-circulate. SmartButtons have a memory of 2048 readings, and an operating range of -40°C to +85°C.
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 16-Mbytes of RAM, a color monitor, and a pointing device. The platform must run Windows 95, Windows98, WindowsNT, Windows2000, or Windows XP.
A USB (Universal Serial Bus) 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.
