IoT Project: Wireless Sump Pump Monitor

Do you worry about your basement flooding? You can build a microcontroller-based, three-unit wireless system can monitor the water level in your sump pit. David Kanceruk's Pump-Eye is a three-unit water level monitoring system built around a Freescale Semiconductor 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%. Continue Reading
