The company claims that Sensa Spa, an automatic spa sanitizer, deploys bromine tablet passively and senses and dispensing the right amount of shock. This keeps hot tub water within the optimal sanitizer level for up to one month without any user interaction. Sensa Spa floats in the hot-tub and releases shocks as required with minimal user interaction. The system has sensors that detect movement, pH, sanitizer level, temperature, and bathers’ presence.
