The aim of this project is design a system to monitor the vital signs of a patient by using the compact bio-medical wireless sensor notes on android By using project we can continuously monitor a priority based patient health conditions during unfortunate seriousness of the patient and give the service by wireless transmissions between medical devices and continuously monitor the core temperature and carbon dioxide concentration. Now a day with the increase of biomedical sensor we are going into this process of detecting the patient’s real-time body temperature, heart rate and other physiological information’s .Coming to the main core of wireless medical monitoring system is the design of wireless monitoring terminal, and the development of system software. The monitoring terminal generally consists of three modules: the sensor module, the control module, and the wireless communication module. The sensor module is used for acquiring medical information from the outside, and then converts them to digital signals. The wireless communication module mainly deals with the wireless transmission of information. Nowadays, there are various kinds of wireless communication protocols. But since the main task of a monitoring terminal is to realize the transmission of signals such as heart rate, body temperature, and calling signals the data traffic is not heavy. Moreover, because the monitoring terminal is worn on patients, which needs to be supplied by battery, it puts a high demand on the reducing of power dissipation of wireless transmission module. Having taken these comprehensive factors into consideration, this paper chooses the WIFI technology as the wireless communication protocol. WIFI technology is a mid range, low-rate, low-power wireless communication technology.
