Nov 28, 2022 · Arduino Code Example For The Oxygen Sensor Project. In this section, you can find the complete Arduino sketch and the information on installing the necessary libraries. The complete Arduino Code For The DFRobot Oxygen Sensor. The default I2C address is 0x73. If you modify the hardware address, make sure you also update the code accordingly.
The formula for calculation the O2 % is simple. (current mv from sensor / mv from sensor in the air) *20.9. The only thing you need to do is store the "mv from sensor in the air" value in a variable before you try to analyze any gas. I do this in setup routine of my sketch or when you press the push button.

Jun 30, 2015 · The basic design is a sensor (2 conductor) that self generates a low voltage potential based on the partial pressure of O2 that it senses. Air at 21% will be between 8-13 mV and full scale 100% O2 is linear to about 65 mV. Most readings will be in the 30-40% O2 range with a 0.1% O2 readability desired.
Feb 9, 2024 · This day i Test the second version of this project. Using arduino NANO and OLED display. It is strange!! This project only works when I put a dark plastic (packaging of the sensor) between my finger and the sensor. Then I get right data for O² and heart rate. When I put my finger directly on the sensor, the data are zero. Strange!!
Feb 5, 2019 · Wiring: The MAX30102 Can use the i²c ,so wire it with the Arduino board using the usual A4/A5 with SDA/SCL same with the OLED, the first is powered by 5v and the second by 3.3v, the buzzer is also using 5v/GND and it’s I/O wired with D3, if you’re using 2 pins buzzer: GND with GND and (+) (don’t forget a resistor) with D3.
Fortunately wiring up the LuminOx O2 Sensor to an Arduino is super easy. In the code example below we will use pins 10 and 11 to communicate with the sensor. So you can wire it up as follows. sensor pin 1 -> 5V power sensor pin 2 -> Ground sensor pin 3 -> pin 10 sensor pin 4 -> pin 11 . LuminOx Sensor and RedBoard; Arduino Code for LuminOx O2 ...
