1. A device for monitoring a concentration of sanitizing compounds in water, comprising:
a power module;
a sensor part comprising a plurality of sensors; and
a control and indicator part, comprising:
a processor in operable communication with an indication module and non-transitory computer memory having programming that, when executed by the processor, performs the following steps:
executing a calibration stage, comprising:
determining, via at least one sensor of the plurality of sensors, a temperature of a sample of water from a water source, the sample of water being devoid of sanitizing compounds;
measuring, via at least one sensor of the plurality of sensors, a characteristic of the sample of water; and
measuring, via at least one sensor of the plurality of sensors, a baseline resistance of the sample of water; and
executing an operational stage, comprising:
determining a resistance of a sanitizing solution, wherein the sanitizing solution comprises water from the water source and at least one sanitizing compound;
calculating a concentration of the sanitizing solution, wherein the concentration is based on the temperature of the water sample, the characteristic of the water sample, and the baseline resistance of the water sample;
comparing the calculated concentration to a predetermined threshold concentration stored in the memory; and
activating the indication module based on the comparison of the calculated concentration to the predetermined threshold concentration.
