Data logger for multiple carbon dioxide (SCD30) and oxygen ...

2019-07-20· In this project, we recorded CO2 and O2 data from six Sensirion SCD30 and Grove-ME2-O2 sensors using Arduino MEGA. While the ME2-O2 produce analog output, the SCD30 communicate via the I2C interface. Each SCD30 sensor has the same permanent I2C address, therefore, we use TCA9548A I2C multiplexer to read multiple SCD30. The real-time data was displayed using low power …

Easy to Build Oxygen Analyzer Using an Arduino Compatible ...

Introduction: Easy to Build Oxygen Analyzer Using an Arduino Compatible Micro Controller . As a builder of gadgets and a scuba diver I have been trying to build an oxygen analyzer for a bit now. The big problem is that most micro controllers can’t read the mv that the sensor puts out. I played with opamps, but never got it to work properly. Finally I found the Texas Instruments ads1015, an ...

How to use KE-25 Oxygen Sensor with arduino -

2020-08-24· So to make easier to read with an arduino. We should amplify the sensor first. I use an LM358 op amp IC to amplify the sensor output. I amplify the sensor 11 times. So i use non inverting op amp with 100k and 10k of resistors. KE-25 oxygen sensor amplifier schematic. The arduino sketch is easy since this just an analog sensor. We just need to read the ADC value. void setup() { ...
