DIY CO2 Incubator - Possible Improvements

14/12/2014· Find a cheaper CO2 sensor or coming up with a DIY version. This needs some thought, but starting with the components required for an NDIR sensor is a place to start. The sensor used in this project is by far the most expensive part and represents about ~60-70% of the total project cost. Cheap CO2 sensors would not only decrease the cost, but would also allow for multi-point measurements …

Adafruit SCD-30 - NDIR CO2 Temperature and Humidity Sensor

25/07/2021· 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 concentration! That means its a lot bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific ...

How does an NDIR CO2 Sensor Work? |

Today's newest generation of CO2 sensors has even more optimized waveguides, allowing a longer optical light path to be folded into an even smaller. 8 mm x 33 mm x 20 mm footprint. In addition to a smaller size, new mid-range infrared light-emitting diode (LED) light sources have been developed that allow NDIR sensors to operate at much lower power levels. Combined with a photo-diode light ...

CO2 Monitor - Arduino Project Hub

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 ...
