Arduino | Adafruit SCD-30 - NDIR CO2 Temperature and ...

Jul 09, 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 concentration! That means its a lot bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific ...

Optical O2 Sensors

Our oxygen sensors cover a measurement range from 1 ppb up to 45 ppm dissolved oxygen, and even measure ultra-low oxygen traces down to ppmv O 2 in gases. Compared to other methods, optical O 2 sensors do not consume the analyte during measurements, which is an important advantage when measuring in low oxygen environments. All of our oxygen sensors come pre-calibrated, and with a …

Sensing CO2, O2, CO not MG / MQ sensors - Arduino Forum

May 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.
