Gravity: Analog ORP Sensor Meter for Arduino Crystals Now we have a wirelessly-rechargeableIn the ever increasing need and awareness for health and safety, water has become a focus point for proper disinfection treatment as aftereffects of industrialization can become a danger for contamination of water via direct contact. Water is a critical control point of contact where proper treatment can greatly reduce these microbes, thereby reducing the chances of illness and pollution. While traditional ORP meters are hard to get or use, this
