Heart rate and body temperature are important health parameter that need to be monitored especially for the old aged that needs constant medical care. In this study, simulation and construction of wireless body temperature and heartbeat monitoring device was carried out using PIC16F886 microcontroller and RF module. The circuit was simulated using Proteus8.4, while a prototype was constructed on a Vero board. The circuit was tested by measuring temperature and heartbeat of 20 volunteers during different levels of activities. Result shows that, the transmitter section, reads body temperature and heartbeat using sensors. The signal is then processed by the microcontroller and wirelessly transmitted to the receiver section through RF module at 433MHz, while detail is displayed on the LCD. At the receiver section, the signals are received through RF antenna operating at the same frequency with the transmitting RF module (433MHz). The data processed by the receiver microcontroller is also displayed on LCD. The readings of body temperature and heartbeat can be taken simultaneously by the same device and transmitted wirelessly to the care giver or patient relation. The device recorded a heartbeat rate of 76bpm at normal body temperature of 36.2°C and for every degree increases in body temperature, the heart beats about 10bpm faster. The device is reliable and cost effective to enable it accessible and affordable to the care giver and patient’s relative who can monitor the patient remotely.
