2021-05-06· Hi all, I am relatively new with Arduino. I am doing a project were I need to measure CO2. I have been working with the cheap MQ 135 but I am unhappy about its accuracy and range. Could it be that I am doing something wrong? The code I have been using belongs to Davide Gironi: I burned it in for 48 hours and used his code here posted. The values are not stable at all and after calibrating ...

2021-07-04· For evaluation purpose the monitor can record the CO2 data for about 5 days and replay them to the COM-interface of the arduino nano. As the CO2 sensor needs some 100 mA when it is in action, the monitor cannot be powered by the arduino directly but can be powered by either a typical 5 V USB power supply/power bank or a generic 7 V - 12 V power supply. Features: sensitivity range from …

While the Arduino's 5V power is theoretically able to power the K-30, the sensor needs 300mA minimum to operate the light inside the sensor. The problem is, if you power the Arduino from your PC's USB port, the K-30 has to share power with the Arduino, your mouse, and any other devices on the USB bus. The power to the sensor …
2021-07-25· 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 ...
