CO2 Monitoring with K30 Sensor - Arduino Project Hub

This project is about monitoring CO2 levels at home, in the greenhouse, in that small office, etc. ... I uploaded a I2C library for this sensor on Github: K30_CO2_I2C_Arduino. This photo shows K30 connected to Arduino. CO2 measurements are displayed on LCD1602 screen. And here is a close-up of the sensor. It can also be connected over serial and it has a 400 ppm calibration switch ...

CCS811 carbon dioxide sensor breakout and the Arduino ...

2020-11-26· Here we connect a CCS811 carbon dioxide sensor breakout board to an Arduino. The CCS811 measures the concentration of carbon dioxide and volatile gases in atmospheric air. Introduction Every time we breathe we take in some oxygen and we release a certain amount of carbon dioxide. One average person is believed to release as much as two pounds of carbon dioxide per …

Gas Sensor Applications |

To give one example, we were able to work with a student specifically who was looking to measure CO2 levels both indoors and in his community. By utilizing the K30 10,000 ppm CO2 sensor and Arduino Uno Micro-controller, the student was able to pinpoint what his communities system was currently lacking.

Air Pollution Detector: a CO2 Level Using MG-811 : 4 Steps ...

I found that an MG-811 CO2 sensor is quite enough to make a good demonstration of my idea. Although I read about how much people are struggling to make it work (check the Arduino forum) I decided to take the challenge and with my fingers crossed =) An advise when buying that sensor: you'll find many flavors of this sensor's packaging from different vendors, and by packaging I mean the breakout ...

Air Pollution Monitoring System using Arduino and MQ135 ...

2020-12-19· When we turn on the system’s power supply, the MQ135 gas sensor starts sensing NH3, NOx, alcohol, Benzene, smoke, CO2, and some other harmful gases and it gives the output in form of voltage levels. This output voltage goes to the Arduino. Then the Arduino converts this voltage into PPM (parts per million) value with the help of the “” library which is defined in Arduino Code ...

ESP32 Arduino: Using an infrared CO2 sensor - techtutorialsx

2018-05-03· The Analog Infrared CO2 sensor allows to measure the CO2 air concentration in a range from 0 to 5000 ppm (parts per million), with an accuracy of ± 50ppm + 3% of the reading [1]. The sensor operation is based on the NDIR technology (nondispersive infrared) and includes temperature compensation [1]. This sensor can operate with a voltage supply ...

Arduino Based Air Pollution Control

The Arduino keeps reading the CO2 level from the gas sensor and if the current CO2 level increases beyond the threshold level, it activates the buzzer and sends a HIGH logic to relay connecting pin switching the air purifier ON. When the CO2 level is again reduced to a permissible level, the Arduino switches OFF the air purifier by sending a LOW logic at the relay connecting pin. Check out the ...
