| dc.description.abstract | The issue of plastic waste, particularly multilayer plastic, continues to escalate due to
its highly non-biodegradable nature. Pyrolysis offers an effective method for
converting plastic waste into gas that can be utilized as an alternative energy source.
In this research, an Internet of Things (IoT)–based gas storage system for pyrolysis
products was successfully designed and developed to enable real-time monitoring of
temperature and pressure, as well as automatic relay control throughout the
operational process. A Type-K thermocouple integrated with the MAX6675 module
was used to measure reactor temperature, while a pressure transmitter monitored the
gas pressure in the storage tank. All data were displayed on a 20×4 LCD and
transmitted to the ThingSpeak platform using the ESP8266 module. Automatic control
of the solenoid valves was implemented through a dual-relay system based on
predefined pressure limits. The experimental results showed that the pyrolysis process
successfully generated gas with temperature increasing from 35°C to approximately
240°C and pressure reaching up to 3 bar. Both temperature and pressure sensors
demonstrated stable and consistent performance, as reflected in both on-device
readings and IoT-based monitoring. The automatic control system effectively switched
relay operation once the pressure threshold was reached, ensuring system safety and
operational stability. The produced gas was also successfully applied to a 5500-watt
generator, enabling it to operate stably for approximately 5 minutes with a consistent
output of 220 volts. These findings demonstrate that integrating pyrolysis with IoTbased instrumentation enhances monitoring efficiency, operational safety, and the
potential utilization of pyrolysis gas as a viable alternative energy source. | en_US |
