Contact SupplierThis project aims at monitoring the patient’s health conditions continuously. The parameters like the blood pressure, temperature, heart beat are to be monitored continuously. In other words, the doctor will be diagnosing the patient continuously. This project uses the wireless concept, ZIGBEE. ZIGBEE is a specification for a suite of high level communication protocols using small, low-power digital radios based on the IEEE 802.15.4-2003 standard for wireless personal area networks (WPANs), such as wireless headphones connecting with cell phones via short-range radio. The technology defined by the ZIGBEE specification is intended to be simpler and less expensive than other WPANs, such as Bluetooth. ZIGBEE is targeted at radio-frequency (RF) applications that require a low data rate, long battery life and secure networking. The project is designed in such a way that, the analog quantities which are to be recorded continuously are taken and converted into corresponding digital values using an eight channel ADC. Here we consider temperature and pulse oxymeter sensors to monitor the temperature, blood pressure and heart beat respectively. The processed data from ADC is sent to microcontroller. The microcontroller continuously monitors the status of the sensors and the X-Bee transceiver will be interfaced to the microcontroller through serial communication to pass the corresponding sensors data to the control room PC. The Pc will be also interfaced with another X-Bee transceiver through serial communication. The doctor can continuously check the patient’s status by checking the parameters displayed on the PC and will take the immediate action if the parameters exceed the normal values. This project uses regulated 5V, 500mA power supply. Unregulated 12V DC is used for relay. 7805 three terminal voltage regulator is used for voltage regulation. Full wave bridge rectifier is used to rectify the ac output of secondary of 230/12V step down transformer.
