Read Two KSeries CO2 Sensors with Arduino Uno |

So when using the Arduino you may address multiple sensors as unique devices, like I2C devices. With the addition of a 485 transceiver at the Arduino and each sensor the UART RX/TX from the Arduino can communicate with multiple sensor slaves. The sensors provides a R/T line to control the transceivers direction when it respond to an inquiry from the Arduino master.

Why measure CO2 in HVAC applications? |

Instead of constantly providing fresh air, buildings used carbon dioxide sensors to “sense” when the buildings were occupied. When enough people enter a room, the CO2 level rises because of the CO2 from their exhaled breath, and the HVAC system begins to bring in the fresh air. When the people leave, the CO2 level drops because they are no ...
