Pump-Eye
The flexible Pump-Eye is a three-unit water level monitoring
system built around MC9S08GT60 and MC9S12NE64 microcontrollers.
The sensor unit monitors the water level in a sump pump pit,
the sump pump’s AC power, and the sensor unit’s backup battery.
The base unit receives status information from the sensor
unit via RF. The sensor and base units use MC9S08GT60 microcontrollers;
they communicate with each other via 2.4-GHz transceivers
based on an MC13192 SARD board. The Ethernet link creates
and sends timestamp and log messages to a host when the pump
runs. The system sends a warning e-mail when the water level
is high or there’s a power failure. An alarm sounds when the
water level exceeds the normal maximum height by 10%.
