Arduino CO2 Meter Arduino Project Hub
In this project, we will be making a benchtopstyle CO2 meter using the sensor from Atlas Scientific hooked up to an Arduino Uno. The realtime readings in PPM will be shown on a liquid crystal display (LCD). Both the sensor and display are connected to the Arduino via I2C. Note: This device was developed and tested using a Windows computer.

Recommendations for CO and CO2 sensors please : arduino
1. level 1. briandonovan. 1 year ago. The Sensirion SCD30 does CO2, temperature, and relative humidity. It can communicate via I2C and, thanks to Sparkfun, there''s a working Arduino lib for the SCD30 on GitHub. I bought a couple of these sensors and, after using them for a few weeks now, would have no qualms about buying more.
Carbon Monoxide Gas Sensor MQ7 Arduino Project Hub
I had previously published a project with an MQ sensor and received a lot of critical feedback on it. Today I also expect your feedback, but only of a positive nature: with the MQ7 carbon monoxide gas sensor and the matching PCB from Pololu, analog measurement using the ADC from the Arduino is no longer a problem.
MQ7 Carbon Monoxide Sensor Circuit Built with an Arduino
MQ7 Carbon Monoxide Sensor Circuit Schematic. The carbon monoxide sensor circuit we will build with an MQ7 sensor integrated with an arduino is shown below. The connections are pretty basic. To connect the sensor, there are 4 leads. 2 of them are for power. The +5V terminal of the sensor connects into the 5V terminal of the arduino board.

28/10/2019· The difference between analog and digital sensors is that an analog sensor collects readings over a range of values, and a digital sensor only reads a HIGH or LOW signal (a bit of data). The Arduino has a 10bit AnalogtoDigitalConverter (ADC), which maps sensor readings between 0 and the operating voltage (5V or ) into integer values between 0 and 1023.
