Abstract:

Built with a 68HC908QT4, an optically isolated remote alarm interface, a low-dropout voltage regulator, a 9-V battery, and a few sensors, the Enviro-Alarm monitors for leaks around a basement sump pump. The remote alarm interface connects to a Cat 5 cable that runs to a wiring closet for integration with a PC-based home automation system.
