How does an NDIR CO2 Sensor Work? |

Serial output is especially useful for using NDIR CO2 sensors with Arduino or Raspberry Pi microcontrollers. Early CO2 measurement devices. Since Joseph Black, a Scottish chemist and physician first identified carbon dioxide in the 1750s, scientists have looked for a way to measure this common gas. One of the earliest CO2 measurement devices was a mercury manometer. Manometers use a U …

50 of the most important Raspberry Pi Sensors and Components

The DS18B20 and DS18S20 represents a very simple sensor. These Raspberry Pi sensors are addressed via the so-called 1-wire bus. An advantage is that many different 1-wire components can be connected in series and read out by a single GPIO. However, these modules can not measure additional information such as humidity and / or air pressure. The ...
