ODAX PPG Standard Sensor Kit

ODAX PPG Standard Sensor Kit hero

Reflective PPG sensor kit with the ODAX Reflective PPG Sensor board in a black enclosure, providing a filtered analog waveform for a host ADC.

Overview

The ODAX PPG Standard Sensor Kit — ODAX Reflective PPG Standard Sensor Kit - Sensor Board with Enclosure — combines the ODAX Reflective PPG Sensor board with a black enclosure for reflective finger photoplethysmography (PPG) experiments.

The kit is based on the ODAX-PPG-SR1-100-STD-R1 board. Its green optical emitters and photodiode sense changes in reflected light at the finger, while the analog front end conditions the signal and provides a filtered voltage output for a host ADC. Pulse detection and rate estimation are performed by your own firmware or software.

The Sensor Board Inside

The ODAX Reflective PPG Sensor, identified as ODAX PPG Standard in the datasheet, uses an ams OSRAM BIOFY SFH 7072 optical module with two green emitters and an IR-cut photodiode. Its analog signal path converts photodiode current to voltage, suppresses the steady optical background, amplifies pulse variations, and filters the output.

Applications

Getting Started

  1. Review the board datasheet and verify the actual cable connections to VCC, GND, and VOUT before applying power.
  2. Connect VOUT to a high-impedance host ADC input and share the signal ground. Use a clean supply within the board's documented range and keep the output within the ADC's permitted input range.
  3. Position the finger over the sensing area with light, consistent pressure. Support the hand and cable and shield the sensor from strong ambient light.
  4. Allow the baseline to settle, then acquire and process the analog waveform using your host system.

See the sensor board's getting-started guidance for acquisition and signal-interpretation details.
