Design and Development of PIC Microcontroller based Wireless Architecture for Human Health Monitoring

Kalpana PM

This project presents the implementation of PIC microcontroller based wireless architecture for human health monitoring system using the two sensors are used namely, temperature and pulse heart rate. The temperature sensor is used to continuously monitor the body temperature. The pulse heart rate sensor is used to measure the heart rate by sensing the change in blood volume in a finger artery while the heart is pumping the blood. The sensors output are given to the signal conditioning circuit to condition and amplify the sensors output and as a result of voltage value. These sensors output are interfaced with PIC microcontroller and data is transmitted to the node wirelessly using zigbee (MRF24J40), which passed the data’s to a PC. The readings of the sensor are noted and the information is broadcasted into the network. These readings are stored, transmitted, received and displayed data’s in the server continuously. This provides a painless, automated way to collect a large amount of sensors data. Finally, it send these data’s to Visual Basic based software by using the Serial communication port.
