Product Overview

Ear Lobe Pulse Oximeter Sensor, also known as an earlobe pulse oximeter or ear clip sensor, is a medical device used to measure oxygen saturation levels and pulse rate. It is a non-invasive sensor that is typically attached to the ear lobe. The ear lobe sensor utilizes a technology called pulse oximetry, which works by emitting light into the tissue and measuring the amount of light absorbed by oxygenated and deoxygenated blood. By analyzing the light absorption, the sensor can determine the oxygen saturation level (SpO2) and pulse rate of an individual.

The sensor consists of two components: a light-emitting diode (LED) and a photodetector. The LED emits two wavelengths of light, typically red and infrared. The photodetector measures the intensity of the light that passes through the ear lobe tissue. Based on the differences in light absorption between oxygenated and deoxygenated blood, the sensor calculates the oxygen saturation level and pulse rate. The device is placed on the ear lobe region of the ear.


  • Easy Interface with Arduino and other microcontrollers.
  • 5V and 3.3V dual digital output.
  • Fast Response and Accurate Results.


  • Ear lobe sensors are commonly used in medical settings, such as hospitals, clinics, and during surgical procedures.
  • They are also used in some consumer-grade pulse oximeters for personal health monitoring.
  • The ear lobe sensor provides a convenient and comfortable method of monitoring oxygen levels and pulse rate, as it can be easily attached and removed from the ear lobe without causing discomfort or pain.
