Abstract
A wireless child-friendly health monitoring system that records photoplethysmogram (PPG) signals has been built. It uses low cost LEDs as optical receivers. It was shown that the recorded PPG signals are larger in magnitude by nearly five times when using four LEDs in a suitable formation as photo detectors. The PPG signals were transmitted wirelessly and stored on a PC. The signals were processed to extract heart beat rate, respiration rate and SpO2 blood oxygen saturation level. The results that demonstrated the effectiveness of the device's operation are presented.
