IMUNES : design and implementation temperature and heartbeat sensors in measuring vital sign through watch

Development of technology will always increasing and end up with many task are able to do something with a simpler way. That way, usually, will be came up with potentially of light illness and continuously accumulate became a big serious one. This systems aim to be constant remainder for user´s condition of temperature and heartbeat, so that, the user´s temperature and heartbeat will always monitored anytime and anywhere by this device. Temperature measurement is aquiring by infrared sensors which put on forehand and get temperature measurement error data less than 5% comparing to measurement by conventional medical thermometer. whereas heartbeat measurement is aquiring by a couple of infrared and phototransistor and some analog circuit for conditioning electrical signal. The result of heartbeat measurement has an error less than 8% comparing to measurement using pulseoximeter. The two measurement data will be added to watch systems as extra function, so that the measurement activities will not interrupt the user´s activity. Next, the measurement data will be synchronized with cloud eHealth server through mediator devices which has android platform, the interconnection between watch and cell phone is complete by bluetooth protocol.
