Onset Computer Corp., a supplier of battery-powered data loggers, introduced new Real-Time Alarm Software for use with HOBO data loggers. The new alarm software automatically notifies users via cell phone text messages or email when temperature, humidity and other conditions exceed user-defined limits. The software is able to provide alarm notification for multiple HOBO data loggers, and can be used with Ethernet servers. The Real-Time Alarm Tool is a plug-in software module to Onset's HOBOware software package, available for both PC and Macintosh computers.
