Abstract Introduction With the increasing importance of protecting workers from exposure to hazardous chemicals, there is a growing demand for integrating ICT technologies, especially IoT, into workplace environment monitoring systems. In this study, we present the development and implementation of an IoT-based smart sensor device specifically designed to detect TVOCs in the workplace. Methods An IoT-based smart sensor chemical monitoring system was developed and implemented in the electronics industry. The system used a TVOC sensor, an LTE communication module, and a web-based platform. The system was mainly used for tasks such as inspection and equipment cleaning. In the actual workplace, the system was applied to a workplace that performs cleaning in the electronics industry, which uses TCE as a degreaser. Results It is possible to identify the processes that generated TVOCs. The monitoring system, placed closer to the source of the chemical emissions, often showed elevated exposure levels. In particular, 28% of the data from the jig cleaning operation exceeded the STEL, indicating that it could be used to prevent acute poisoning by immediately identifying exposure. Discussion Incorporating IoT technology into workplace monitoring systems can provide real-time data to supplement traditional workplace environmental assessment methods. In addition to identifying overall exposure levels, the system can pinpoint short-term and peak exposures, which is essential for preventing occupational acute poisoning accidents. Conclusion IoT-based smart sensor monitoring systems have significant potential to improve worker protection from chemical hazards by ensuring accurate, rapid, and thorough exposure to prevention.
