Interfacing Gravity Infrared CO2 Sensor with Arduino to Measure Carbon Dioxide in PPM The increasing concentration of carbon dioxide in the air has become a serious problem now. According to the NOAA report, the ozone CO2 concentration has reached 0.0385 percent (385 ppm) and it is the highest amount in 2.1 million years. This means that in one million particles of air, there are 385 particles of carbon dioxide. This rising level of CO2 has affected the… |

Li-Fi based Text Communication between Two Arduino Li-Fi (Light Fidelity) is an advanced technology that allows transferring data using optical communication, such as visible light. Li-Fi data can travel through the light and then be interpreted on the receiver side using any light-sensitive device, like an LDR or a photodiode. Li-Fi communication can be 100 times faster than Wi-Fi. In this comprehensive guide, we'll… |
