Also provided is a biomonitoring mirror device that identifies a user, detects a febrile illness in a user, dispenses medications/supplements, connects to electrical device accessories in the bathroom, and provides an interactive user interface. Additionally provided is a system for measuring a parameter of a material expelled during use of a toilet by a user. Further provided is a method of determining a physiological parameter of a user. ## Claims ### Claim 1 A biomonitoring device that measures a parameter of a material expelled into a bowl of a toilet by a user, the device comprising (i) an electromagnetic radiation source above the material, wherein the electromagnetic radiation source emits electromagnetic radiation into the bowl of the toilet, and (ii) a sensor comprising a lens above the material that detects electromagnetic radiation or an analyte chemical in the bowl of the toilet, wherein (i) and (ii) are behind a sitting portion of a seat of the toilet, and wherein the lens is situated such that it does not change position, relative to the bowl of the toilet, when the seat of the toilet is lifted. ### Claim 2 (depends on 1) The device of claim 1, wherein the sensor is an image sensor comprising the lens. ### Claim 3 (depends on 2) The device of claim 2, wherein the sensor further comprises a complementary metal-oxide-semiconductor. ### Claim 4 (depends on 1) The device of claim 1, further comprising components for spectroscopic detection comprising a laser diode and a photodetector. ### Claim 5 (depends on 1) The device of claim 1, wherein the sensor detects an analyte chemical in the bowl. ### Claim 6 (depends on 1) The device of claim 1, further comprising a polarization filter. ### Claim 7 (depends on 1) The device of claim 1, further comprising a capacitive sensor that detects the presence of the user while seated on the seat of the toilet. ### Claim 8 (depends on 1) The device of claim 1, further comprising a data storage and/or transmittal unit that stores and/or transmits data from the sensor. ### Claim 9 (depends on 8) The device of claim 8, comprising a transmittal unit that transmits data via wireless, optical or wired communications to a computing unit. ### Claim 10 (depends on 9) The device of claim 9, wherein the device undergoes a training period where data is analyzed when no excreta is in the bowl, wherein the training period comprises taking baseline sample images when no excreta is in the bowl and obtaining a baseline model of the empty toilet bowl from the baseline images. ### Claim 11 (depends on 9) The device of claim 9, wherein the computing unit analyzes the data to determine stool consistency, presence of blood, urine color, urine voiding volume, weight, body composition, stool frequency, urine frequency, or any combination thereof. ### Claim 12 (depends on 1) The device of claim 1, further comprising a scale or footstool comprising a thin film pressure sensor that captures a weight of the user. ### Claim 13 (depends on 1) The device of claim 1, wherein the material is urine or feces. ### Claim 14 (depends on 1) The device of claim 1, further comprising a nozzle capable of dispensing a liquid into the bowl. ### Claim 15 A biomonitoring device that measures a parameter of a material expelled into a bowl of a toilet by a user, the device comprising (i) an electromagnetic radiation source above the material, wherein the electromagnetic radiation source emits electromagnetic radiation into the bowl of the toilet, (ii) a sensor comprising a lens above the material that detects electromagnetic radiation or an analyte chemical in the bowl of the toilet, and (iii) a transmittal unit that transmits data to a computing unit, wherein the device undergoes a training period where data is analyzed when no excreta is in the bowl, wherein the training period comprises taking baseline sample images when no excreta is in the bowl and obtaining a baseline model of the empty toilet bowl from the baseline images. ### Claim 16 (depends on 15) The biomonitoring device of claim 15, wherein the lens is situated such that it does not change position, relative to the bowl of the toilet, when the seat of the toilet is lifted. ### Claim 17 (depends on 15) The biomonitoring device of claim 15, wherein (i) and (ii) are behind a sitting portion of a seat of the toilet. ### Claim 18 (depends on 15) The biomonitoring device of claim 15, further comprising a polarization filter.
