The Internet of Things (IoT) provides a platform that allows devices to connect, discover and remotely control through the internet. This work aims to develop an Internet of Things-based system for an oil company's laboratory. It is intended to monitor its environmental conditions and parameters through air quality sensors, thus providing intelligent monitoring and greater certainty of working conditions. The system development utilizes ESP8266, Arduino UNO processor, solid-state relay, and sensors. The proposed work monitors the air quality, humidity, and temperature of the laboratory environment. It included an active air exhaust control system. A database has been created with the purpose of data analysis and access to status history. As a result of this system implementation, it is expected to improve laboratory management and occupational health and hygiene.
