Smart Intensive Care Unit Desgin Based on Wireless Sensor Network and Internet of Things

A healthcare monitoring system is designed which can be used in the hospitals to monitor people who need to an intensive care. This system can be implemented on many biological signals. ECG signal is selected for put in practice in this work. Since ECG signal is measured in mille volt, it needs to be amplified. Also it is a noisy signal, so it needs to be filtered. ECG acquisition part contains AD620 Instrumentation Amplifier due to its low current noise. The network of patients nodes are require to be available in the intensive care room for measurement. A base node collects these many signals to be monitored in the nursing room. For wireless transmit\receive, nRF24L01+ wireless module is used. ATmega328 MCU in the Arduino Uno board is used in all node. LabVIEW software is programmed to display ECG signals as a waveform chart. For transferring ECG signals to the remote doctor, a Web Pager tool in the LabVIEW program is employed. So the remote doctor could be check his patients condition through internet. The system was implemented for three nodes.
