The EU sets a limit of 3000 ppm of carbon dioxide (CO2) concentration not to be exceeded for broilers, over the entire duration of the flock. Since then, CO2 concentration sensors are developing in French poultry buildings. The purpose of this article is to provide methodological advices for continuous measurement of CO2 concentrations in a broiler house, by looking at CO2 commercial sensors. Despite being the best compromise to measure CO2 concentration at animal’s level according to at the end of the flock at 80 cm +/- 20 cm of height, this can underestimate CO2 concentrations in case of high CO2 productions by animals and litter. These results suggest using more than one CO2 sensors for continuous measurements in poultry barns. According to the sensors’s tests, first level investment should be in high-performance sensor and in its maintenance than purchasing an additional sensor.
