The present invention is directed to a water condition monitoring device and related methods of use that significantly reduce the cost of the water condition monitoring devices by replacing the expensive and bulky multiple sensor electrodes of currently available devices with a single set of two or three metal electrodes to detect and/or measure such water quality parameters as pH, electric conductivity, temperature, and dissolved oxygen content. A microcontroller activates each sensor one at a time in a continuous loop, processing the sensor signals into near real time water condition data, which may be stored, displayed, or sent to a remote location for storage or display.

Universal water condition monitoring device

A tactile sensor includes a flexible medium having electrically conductive strips embedded therein and extending in a first direction, said electrically conductive strips including conductive nanostructures dispersed in a flexible support material, said nanostructures selected from conductive nanowires, carbon nanotubes, and graphene, wherein each electrically conductive strip is connected at each end to an impedance measuring device that measures the impedance across each electrically conductive strip. The electrically conductive strips may be formed on a first layer of the flexible medium by using direct-write technology.
