Abstract
Today, as more and more people own home spas and hot tubs the need for an automated chemical testing and dispensing system has become apparent. Many people have spas located at their weekend getaways and are just too busy to continuously maintain the water, although proper chlorination and pH is essential in inhibiting the growth of bacteria while preventing unnecessary skin and eye irritation. The Spa Commander takes advantages of this fact and supplies the spa owner with a cheap, compact solution for maintaining water cleanliness and safety as there are very few viable automatic calibration systems on the market for home use from both a cost and implementation perspective. Our system will first take in water from the source and test it for pH levels and available chlorine. Then our control system will dispense the required amount of chemicals into the spa water to make it safe. Constant rechecking of water cleanliness and safety will allow our system to maintain a spa's water in an optimal range. As such, the Spa Commander will conform to all pertinent standards and guidelines, including those of the CSA.
