Abstract
In these days of united healthcare, for convenient monitoring of biological signals, the wireless communication technique is necessary. We have investigated several wireless technologies of biological sensor networking for united healthcare. There are some standard techniques such as Bluetooth, wirelesses LAN, ZIGBEE, GSM TECHNOLOGY, etc. We have tested these techniques for biological sensor networking and summarize the advantages and the disadvantages. As a result we decided the GSM TECHNOLOGY to be used as sensor network of patients in the hospital. We developed this patient monitoring system which has several biological parameters. Especially, this system has ability of patient's location awareness in the hospital. The main concept of this project is to provide basic information of the conditions of the just born baby placed in the incubator to the parents by sending SMS through GSM module to the GSM mobile and providing high security such that only authorized medical staff can attend the baby, this information of the baby security is also sent through SMS to the parent. The access to the incubator is authorized through a keypad lock which is entered through a pass code.
