ConnectedYard, an innovator in smart technology and the Internet of Things (IoT), today announced that it has closed a $2.2-million seed round of funding led by Playground Global. The round was also joined by ConnectedYard's pre-seed investor, Tandem Capital. pHin, the company's first product, is reinventing pool and hot tub care by combining a Bluetooth® Smart and WiFi-enabled sensor, a mobile phone app and pre-measured chemicals into a subscription-based solution to take the guesswork out of maintaining chemical balance and water quality.
