Oxygen Level Sensor Arduino

This product is used to measure the dissolved oxygen in water to reflect the water quality.

Oxygen level sensor arduino.

Interfacing max30100 pulse oximeter sensor with arduino. Wiring up luminox o2 sensor to arduino. The blood oxygen concentration termed as spo2 is measured in percentage and heart beat pulse rate is measured in bpm. In this project we will make a device that can measure blood oxygen heart rate using max30100 pulse oximeter arduino.

Fortunately wiring up the luminox o2 sensor to an arduino is super easy. Easy to build oxygen analyzer using an arduino compatible micro controller. The blood oxygen concentration termed as spo2 is measured in percentage and heart beat pulse rate is measured in bpm. I played with opamps but never got it to work properl.

Arduino uno mega or mega256 boards are available from digikey and many other suppliers. Looks like it is 5v tolerant so you should not need a logic level shifter. This is a dissolved oxygen sensor kit which is compatible with arduino microcontrollers. The max30100 is a pulse oximetry and heart rate monitor sensor solution.

I have attached the sketch i have typed out the output i have obtained on the serial monitor the output mv vs oxygen concentration graph of the figaro ke25 sensor i have obtained. The maxim datasheet for the max30102 implies but does not state explicitly that led1 is red and led2 is infrared ir however if the amplitude of led1 is set to zero the red led as depicted in the place finger picture remains lit while if led2 is set to zero the red led is extinguished. It is widely applied in many water quality applications such as aquaculture environment monitoring natural science and so on. The big problem is that most micro controllers can t read the mv that the sensor puts out.

Max30100 pulse oximeter arduino in this tutorial you will learn how to use the max30100 pulse oximeter with arduino and display the heart rate and blood oxygen on a 16 2 lcd the heart rate or pulse rate or heart beat is measured in bpm which is also known as the beats per minute while the blood oxygen concentration is measured in percentage. While the arduino s 5v power is theoretically able to power the k 30 the sensor needs 300ma minimum to operate the light inside the sensor. In the code example below we will use pins 10 and 11 to communicate with the sensor. Driver issue the maxim max30102 sensor used is mounted on a mh et live breakout board.

I have been trying to interface the figaro ke25 2 lead fuel cell type oxygen gas sensor with arduino uno i am not getting the required output on the serial monitor for regular air oxygen concentration of 19. So you can wire it up as follows.
