This article presents a study that addresses the importance of indoor air quality. The research aimed to understand how the use of specific plants can enhance air quality in work environments. The methodology involves a prototype with two sensors to measure CO2 concentration in a space without natural and mechanical ventilation, considering the use of plants for air purification. The results demonstrate the variation in CO2 levels with and without the presence of plants and occupants. While a reduction in CO2 levels was observed with the use of plants, under high occupancy, the vegetation wasn't sufficient to maintain recommended levels. The conclusion emphasizes the need for sensor calibration, as well as the proportional relationship between CO2 accumulation in the environment and the quantity of plants required to uphold air quality.
