06/05/2021· Hi, I am working on a project designed to measure oceanic CO2 levels, and for this I need to be able to run an air pump and a K33 sensor off of an arduino. The set up I have turns on the air pump for 15 seconds (via a Drok 7A output motor driver), turns it off, takes a CO2 reading, waits a bit, and then turns the air pump back on. However, I have run into a problem. I have made a functional ...
18/06/2018· I used an Arduino Nano to read the values from the sensor and send them to the laptop over the USB connection that was also powering it. The sensor can be calibrated in atmospheric CO2 conditions at the push of a button. I have reservations about this onepoint calibration but “you pays yer money…”, as my dad used to say. The Nano is sitting on a screw terminal shield with mount holes ...

06/05/2021· I have the following sketch for getting data from a co2 sensor. I attached the schematic. The issue I’m having: The sketch seems to reset randomly. I can tell because it runs through void setup multiple times. include <> SoftwareSerial mySerial(12, 13); // RX, TX pins on Ardunio int co2 =0; double multiplier = 1;// 1 for 2% =20000 PPM, 10 for 20% = 200,000 PPM uint8_t buffer ...
Despite my confidence in having a (relatively) new catalytic converter and a new O2 sensor, my lovely 1994 BMW 325i Convertible got flagged as a "Gross Polluter." The test results are summarized below: CO2 O2 HC CO NO 333 ~80 Essentially, HC and CO are far too high while NO is fairly low. Also, CO2 is low, indicating lean conditions.
Student project combines CO2 sensor, Arduino Uno. February 20, 2018. Today’s students need to be prepared for tomorrow’s technical jobs. To help them achieve this goal, Walt Whitman High School in Huntington Station, NY hired Fred Feraco, Science Research Program Teacher, to do that job. Mr. Feraco is the sole Research Teacher at Whitman.

The molecular weight of CO is , where the molecular weight of CO2 is This means that the CO2 gas is much more dense than CO. CO2 will collect near floor level while CO will collect closer to the ceiling. OSHA lists danger levels for CO beginning at 35 ppm, and for CO2 starting at a 5,000 ppm timeweighted average.

If desired, the unit can be connected to a computer to display the evolution of CO2 and TVOC in realtime. Technical principle. The air quality is measured with the popular CCS 811 sensor, connected to the Arduino via I2C. The communication with the LCD display is also done via I2C (other displays and/or communication modes are certainly ...

CO2 = 410*ppm*(Rs/f_RH_T / Rs410/f_RH_T_410)^b. Where the exponent b is equal to according to Mad Frog. And where Rs410 is the sensor resistance measured in clean air (410 ppm of CO2) and f_RH_T_410 is the correction factor at the moment that the clean air sensor resistance is measured. Here we assume that the correction factor as a ...
