[PhysioLab] Assembly Biosignal Kit Series/ PPG-KIT (PhotoPlethysmogram)

Introduction

It is an educational kit which measures PPG signals from finger and outputs analog signals through amplification and filtering. It is provided with raw materials and user's manual and helps students understand principles of measuring the PPG including components, filtering methods and electronic circuits through assembling, checking and measuring.

The probes to measure pulse waves are internally or externally located and the internal probe is a PPG sensor fixed to the board. The notch filter is excluded because the PPG signal is detected by the light. LED light through the Beat detection and the IVC volume are designded to adjust sensitivity of the pulse wave depending on personal features or force of pushing the sensor.

The kit measures PPG signals and connects the company's test kits(μDAQ-KIT and SimDAQ-KIT) to monitor precisely and accurately outputs for each biosignal processing step
