    • The Honeywell Water Sensing Alarm has three components:

    • Sensing Cable

    • Extension Cable

    • Base Station

    • Disconnect the RJ-11 jack that connects the base station to the extension cable.

    • Disconnect the RJ-11 jack that connects the extension cable to the sensing cable.

    • Pop open the battery case with a fingernail and carefully remove the 9V battery without breaking the 9V battery connector still attached to the battery

    • Disconnect the 9V battery connector from the battery

    • Unscrew the 4 screws holding the plastic enclosure together with the Phillips #1 Screwdriver

    • The circuit board slides off of plastic standoffs for closer inspection

    • The circuit board has three notable components

    • Microchip PIC12F510 8-bit microcontroller

    • Piezoelectric buzzer for water alert

    • RJ-11 Connector

    • The Microcontroller provides a signal for the speaker and interprets the signal coming in from the RJ-11 connector.

    • The Microcontroller runs off 2.0-5.5V (from datasheet here) so the board also regulates the battery 9V down to a voltage usable by the microcontroller.
