[Project] Air Quality Logger: CO2, Fine ... - Arduino Forum

2021-05-21· Especially regarding the carbon dioxide (CO2) level at home. It could effect my sleeping comfort. A commercial device for just measuring CO2 costs around 300 euro/dollar, so I decided to make my own. This post is to share my experience, setup and code, since I used a lot of free libraries as well. In v2 I added a pms7003 fine dust sensor, to see if the air is polluted. Le...

Decent inexpensive CO2 sensor - Sensors - Arduino Forum

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 ...

Interfacing MQ-135 Gas Sensor with Arduino - Electronics ...

2019-10-30· MQ-135 is a gas sensor which is sensitive to CO2. The change in CO2 levels changes the resistance of sensor which results in the change in the output of the sensor. The output generated from the sensor is feed to Analog Input to Arduino board ( In my case Arduino Uno). The analog data is taken by ADC of Arduino, according to the voltage levels, it displays CO2 levels in ppm.

CO2-Monitor - Arduino Project Hub

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 …

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

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 ...
