The Internet of Things (IoT) technology and its applications are transforming objects into smart objects by connecting everything under a common infrastructure to regulate performance via a software application and providing timely upgrades with integrated web servers. In order to improve the quality of life, the green economy, and pollution control in society, comprehensive environmental monitoring systems with simple features and maintenance are required. This study proposes building a wireless sensor network with integrated sensor nodes made with Selective Surface Activation Induced by Laser technology. Electrical circuits may be integrated with free-form plastic sensor housing employing this technology. A low-cost asynchronous web server for monitoring temperature and humidity sensors attached to the ESP32 Wi-Fi module was built in this study.
