Appliances are connected with home network and intellectualization is being rapidly processed. As ubiquitous home is visualized, home sensor is intellectualized and developed with wearable form for the possible inter-home sensor information exchange. Based on the RFID and ubiquitous ID, the home sensors are expected to be developed for the diverse information. The sensor techniques has been intellectualized and diversified by expecting to be developed into perception sensor, extreme environment sensor, micro mechanical sensor, and biosensor. In this paper, the control algorithm of digital control system applicable to the real appliance is suggested. Infrared ray module of appliance is used with the purpose in supporting home network to the appliance in use. And the wireless sign transmitted from home server is transformed into infrared rays sign.

The characteristics of Far-infrared rays mineral water(FIR water) have been compared to the tap water by means of relationship between FIR water and Nuclear Magnetic Resonance spectroscopy(NMR), FIR water and thermography, FIR water and velocity of blood, FIR-water and pH, FIR water and dissolved oxygen(DO), FIR water and Oxidation-Reduction Potential(ORP), using the development FIR water purification of grand prix system. From the experimental result are quite satisfactory when compared with the tap water. Also, the FIR water were evaluated to see if those are tasty and healthy using the Hashimoto's Mineral Balance Index. As a result, FIR-water was found as tasty and healthy.
