which arduino co2 sensor do i need

CO2Monitor Arduino Project Hub

· For evaluation purpose the monitor can record the CO2 data for about 5 days and replay them to the COMinterface 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.

Precalibrated CO2 sensor Sensors Arduino Forum

· What I''m trying to do is to make cheap device that measures temperature, humidity and CO2 (air quality) on 3 points in an apartment with just one Arduino. For temp/humidity I''m thinking to use DHT22, nice, cheap and 1wire sensor (for up to 20m distance). However for CO2 things are not so easy and I need little help here for choosing the right sensor. This will ...

Kohlendioxid CO2 Sensor (Arduino compatible) [SEN0159 ...

By knowing the exact concentration of CO2, we can do somehing to reduce the CO2 and to protect our Earth. For that reason, this CO2 sensor is designed by DFRobot engineer. This is the first CO2 sensor in Arduino market. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer onboard is designed to set the threshold of voltage. As long as the CO2 concentration …
