Water Level Sensor for Bathtub, Jaccuzi, or Pool

INTRODUCTION

The system monitors the water level using a
PIC12C67X. As water flows into the tub, the sensor
monitors the level. When the water reaches a predetermined
level the PICmicro shuts off the flow with a valve.
After the water is drained, the PICmicro™ resets the
valve for the next use. When it shuts off, the system
sounds an alarm. Also, a temperature sensor is incorporated
to prevent scalding
