Smart IOT based technologies can be employed for the efficient monitoring of a patient in the ICU. A smart IOT based ICU patient monitoring project is proposed for this purpose. The IOT connectivity and the digital controller are used to create a smart patient monitoring system. The system utilizes temperature, humidity, and blood pressure sensors to monitor the vital signs of a patient. Diastolic pressure, systolic pressure, and heart rate can be measured using the blood pressure sensor. If any of these vital signs go beyond a certain limit, an alarm buzzer is turned in to notify the concerned personnel.

The power supply module converts 220V AC to 5V DC. The temperature sensor measures the patient’s body temperature, humidity sensor measures the ambient humidity and the blood pressure sensor measures diastolic pressure, systolic pressure and heart rate of the patient.

The data provided by the three sensors is fed to the Raspberry Pi controller which stores and processes this data. The Raspberry Pi is a single board computer which interacts with the input and output devices. The Raspberry Pi controller displays the sensor data on an LCD screen. If any of the sensor values go beyond a certain threshold value, an alarm buzzer is turned on to notify the concerned staff.

The Raspberry Pi controller also sends the sensor data to a remote server based IOT platform by means of on-board WiFi and IOT protocols. The Raspberry Pi controller is programmed using Python language and runs a Linux based OS known as Raspbian. The IOT platform being used in called ThingSpeak. A graphical user interface is built on the Thingspeak IOT platform to show the sensor data in a graphical format.
