Abstract
Internet of Things (IoT) can be used to monitor health conditions of patients after major surgeries. Information from various sensors is processed by PIC16F877A microcontroller which sends data to GSM Network with the help of IoT module. A relay is used to switch between IoT module and GSM module based on the output voltage of the sensors. The data transmitted from the microcontroller is stored on the cloud for long term storage and access. The address of the webpage used should be configured in the IoT module. Alert signal is sent to caretaker in case of emergency. This system is easy to setup with low power consumption and high performance. This system uses GSM network so can be used even in rural areas where broadband facility is not available.
