Building a CO₂ Monitor with Python on a Raspberry Pi ...

Thankfully the Recurse Center is lousy with Raspberry Pis - there’s a box of them along with some Parallella and Arduino boards in the closet - and I was able to scrounge up a Raspberry Pi 3 that was gathering dust. I’ve never really messed with a Raspberry Pi before and it was a fun experience getting it set up. I did need to buy a micro ...

CO2 Gas Sensor | Raspberry Pi - Arduino - Critics Corporation

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 ...

Configure and read out the Raspberry Pi gas sensor (MQ-X)

All MQ-X sensors return analogue signals, which we can not easily read at the Raspberry Pi. One possibility would be to use an Arduino, but we can also use an analog-to-digital converter (ADC), which can be read out via the I2C bus. In addition, we also need a logic level converter. Analog-Digital Converter (8 Ports): US * / UK *.
