GENERAL DESCRIPTION
The Photoplethismography (PPG) sensor isa basic non-invasive sensor to derive pulse
data, complete with cable and accessories tofacilitate placement at the fingertip or ear
lobe. This is an adaptation of thePulseSensor by Joel Murphy & Yury Gitman;
we replace the default wiring by a BITalinocompatible cable to provide plug & play
operation with our kits. Furthermore, we add
a 3D printed casing to protect the wires on
thebackofthesensor.

APPLICATION NOTESThis sensor is designed to measure the changes in reflected light caused by the lightabsorbing capabilities of blood and can be used in the following setups below.
Sensor Protection
Place one of the vinyl stickers onto your sensor to protect the underlying circuit.

Fig. 6. PPG sensor with protection sticker.

Fingertip Placement
Place the sensor at the centre of the velcro fastening strap with its backside (circuit side)placed on the velcro strap. Place your fingertip on the sensor, wrap the velcro strap aroundyour finger, and fasten it.

Fig. 8. PPG sensor fixation around the fingertip.

Alternatively, fixate one of the velcro pads (glue coating side) to the back of the sensor
housing and stick the velcro pad to the velcro strap. Then proceed as above. This method
reduces the movement of the sensor.

Ear Lobe Placement
Apply glue (hot glue) on the backside of the sensor housing, place the flat, inner part of theear clip on the hot glue and wait until the glue has dried out. Clip the sensor to your ear lobe.
