Gravity: Analog ORP Sensor Meter For Arduino is a highly compact ORP monitoring system that fits into your Arduino. This design configuration allows the user to accurately monitor ORP without having to add any additional circuitry or components to your design. Communication with the Gravity: Analog ORP Sensor Meter For Arduino is done using only simple wiring and programing.
Redox potential (also known as oxidation / reduction potential, ‘ORP’, pe, E0‘, or {\displaystyle E_{h}}) is a measure of the tendency of a chemical species to acquire electrons from or lose electrons to an electrode and thereby be reduced or oxidised respectively. Redox potential is measured in volts (V), or millivolts (mV). Each species has its own intrinsic redox potential; for example, the more positive the reduction potential (reduction potential is more often used due to general formalism in electrochemistry), the greater the species’ affinity for electrons and tendency to be reduced. ORP can reflect the antimicrobial potential of the water.
ORP can be used for water system monitoring with the benefit of a single-value measure of the disinfection potential, showing the activity of the disinfectant rather than the applied dose.For example, E. coli, Salmonella, Listeria and other pathogens have survival times of under 30 s when the ORP is above 665 mV, compared against >300 s when it is below 485 mV.
