Is your loved one old and living alone? No need to worry. Using ST Sensor tile sensor we developed a solution fits around your arm in the form of a band, which takes care of this time consuming job leaving your love ones is safe hands!
"The elderly currently represent about 14.5 percent of the U.S. population, and by 2030 there will be about 74 million older individuals. As healthcare costs escalate and pressures are placed on healthcare institutions to provide adequate care, new solutions to managing senior health are imperative."
Smart Health Band will monitor the elderly's steps as well as fall detection sending data to Watson IOT. Caregiver then can monitor the remote patient through a dashboard as well as receiving an SMS when they fall. ST Sensor Tile also have build in motion gesture recognition so in the case when the elder fell down and want to tell the care giver he/she is okay he/she and shake the band and it will send a "I am okay" SMS.
Connect SentorTile to IBM Watson IOT
Following link provide detail steps on how to connect SensorTile to Watson IoT to send all sensors data to the cloud. You will also need to download ST BlueMS iOS app in the App store. Then follow the following instruction in the link.
