Sensing CO2, O2, CO not MG / MQ sensors - …

05-05-2021· Hi - first a quick explaination of 'where I am coming from' :- I recently had a quote for the replacement and re-calibration of the CO2 and CO sensors in my Anton Sprint 2000xt - £350 - and the sensors are only good for 2 years - so another £350 in 2 years time ! What is the Anton ? It is a portable combustion gas analyzer - the type used by gas/oil boiler service engineers. I'm not one of ...

Arduino | Adafruit SCD-30 - NDIR CO2 …

04-07-2021· The SCD-30 is an NDIR sensor, which is a 'true' CO2 sensor, that will tell you the CO2 PPM (parts-per-million) composition of ambient air. Unlike the SGP30, this sensor isn't approximating it from VOC gas concentration - it really is measuring the CO2 …

Data logger for multiple carbon dioxide (SCD30) …

20-07-2019· 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.

Dissolved CO2 sensor - Sensors - Arduino Forum

06-05-2021· Dissolved CO2 sensor. system October 22, 2012, 7:21pm #1. I’m looking to build a sensor for an algae project which reads out the dissolved CO2 content of the algae tanks. This is not easy because the water is opaque and mucky, it’s dissolved, not gaseous CO2, and since the pH is not constant in algae tanks, one cannot use a pH calculation ...

Grove - Gas Sensor(O₂) - Seeed Wiki

Grove - Oxygen Sensor(ME2-O2-Ф20) is a kind of sensor to test the oxygen concentration in air, which is based on the principle of the electrochemical cell to the original work. You can know clearly the current oxygen concentration when you output voltage values proportional to the concentration of oxygen and refer to the oxygen concentration linear characteristic graph.
