The pathogen responsible for COVID-19 is mainly transmitted through aerosol droplets exhaled by infected individuals, which can remain suspended in the air of indoor spaces for up to 8 hours [2]. Therefore, monitoring the air quality in indoor spaces became relevant in order to try to reduce the contagion.La COVID-19 fue identificada en Wuhan, China en diciembre de 2019, y a la fecha, ha causado una pandemia global devastadora [1] El patógeno responsable de la Covid-19 es transmitido principalmente a través de gotículas de aerosol exhaladas por individuos infectados, las cuales permanecen suspendidas en el aire de los espacios cerrados hasta por 8 horas [2]. Por lo tanto, el monitoreo de la calidad del aire en espacios cerrados cobró relevancia con el fin de intentar reducir el contagio.spaAcceso abiertoRed inalámbrica de sensores,MQTT,Calidad del aire interior,Gotículas,COVID-19.57456.23 Q84iTrabajo de grado (Pregrado y/o Especialización)Wireless sensor network,MQTT,Indoor air quality,Aerosol droplets,COVID-19info:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2World Health Organization, “Modes of transmission of virus causing COVID-19: implications for IPC precaution recommendations,” Geneva World Heal.
