in the health care system, patients in the infusion process monitoring problems have been issues of concern to nurses and TEA6425 datasheet and patients, a mistake but will monitor the air into the bodys blood system, resulting in serious consequences even make the patient died. Existing control systems, the use of wired sensor network technology to detect the formation. Such programs are characterized by poor scalability, cumbersome routing, mobility is poor. As a result of the hard-wire connection, the line was easy to aging or corrosion, wear, failure rates are relatively high. Wireless transmission using wireless sensor network built just avoid these problems. In contrast, the wireless way to more flexible, to avoid the trouble of re-wiring, network infrastructure is no longer needed to hide in the wall, ...
