This paper presents a tool for indoor occupancy estimation with Simple Mail Transfer Protocol notification, using a Raspberry Pi embedded board. The system is presented as an alternative to conventional occupancy estimation systems by measuring CO2 levels in the area. The method is based on image processing by applying the background subtraction technique using Python programming language. Initially, the area where the system is tested is characterized, and preprocessing, filtering, and thresholding stages are applied, as well of notification via e-mail for SMTP. The developed system is compared with a CO2 measurement system by applying a prioritization matrix comparing factors such as detection time, hit rate, and implementation costs. The proposed method presented better performance in the totality of the comparison parameters, with a prioritization of 87.972%. Basing the system in open-source software tools and high level and low-cost hardware tools allows for the system to be replicated and implemented on a large scale in controlled environments. 2022 artículo científico 0122-3461 https://www.redalyc.org/articulo.oa?id=85273159003 https://www.redalyc.org/journal/852/85273159003/ https://www.redalyc.org/journal/852/85273159003/html/ https://www.redalyc.org/journal/852/85273159003/85273159003.epub https://www.redalyc.org/journal/852/85273159003/movil 10.14482/inde.40.01.620.427 en http://www.redalyc.org/revista.oa?id=852 Ingeniería y Desarrollo application/pdf Universidad del Norte Ingeniería y Desarrollo (Colombia) Num.1 Vol.40 |
