Claim:
1. A free-floating swimming pool monitor to monitor the presence of a person in a swimming pool when the pool is unattended, said swimming pool monitor comprising: a casing made of a buoyant and water-proof material, said casing defining an inner cavity, an upper portion having an access opening with a removable water-proof lid, and a lower portion having a lower surface defining an electrode groove and an electrode port; electronic circuitry, including an internal power supply, a microprocessor, an Inertial Measurement Unit (IMU), and an electrode extending an outer portion through said electrode port and engaging said electrode groove in said lower portion of said casing, said electronic circuitry integrating to enable said swimming pool monitor to sense and detect the presence of a person in the swimming pool by motion and by microelectronic deviations measured by the electronic circuitry and activating at least one alarm means, wherein said microprocessor is an Arduino or substantial equivalent, which is defined as an open-source prototyping platform based upon easy-to-use hardware and software, which enable circuitry to read inputs and turn it into an output and are programmable by a user by sending a set of instructions to said microprocessor using Arduino language or a substantial equivalent and programming attaching said electrode, said electrode allowing said microprocessor to record the voltage of the water within said swimming pool over a range of alternating current frequencies and further graphed with respect to frequency at a very minute deviation of current which are then analyzed by said microprocessor to determine whether a grounded body is making contact with the water and pool surfaces, and whether or not the body is more likely a human or some other conductive material in a constantly repeating loop in microseconds; a low voltage power supply is a rechargeable battery of less than 27 volts; and said electronic circuitry includes a wireless transmitter which transmits a wireless signal to secondary alert components or alarm system.
