Enhanced IoT-Based Climate Control for Oyster Mushroom Cultivation Using Fuzzy Logic Approach and NodeMCU Microcontroller

Urban farming has the potential to utilise unused space in community alleviate food shortages and increase community’s income through local production. When Internet of Things (IoT) technology is integrated with urban farming, it can further improve its efficiencies yield. The work this paper improved our previous using an IoT-based climate control system regulate cultivation environment oyster mushrooms automatically. Even though could produce two batches mushroom yields, there were several limitations, such as less efficient due threshold-based corrective action, water wastage, instability. This aims address these stated limitations by implementing a fuzzy logic algorithm redesigned system. Two crisp input variables from DHT22 sensors representing temperature humidity fed into Node MCU microcontroller’s coded C language. conditions divided five trapezoidal membership functions resulting 25 rules duration running pump ventilation fan. An internal, lightweight web server managed all HTTP client requests. enhanced also included safety measurement avoid overheating microcontroller causing wastage. Upon analysis data captured months, result showed decrease 40% utilisation yield up 226%. facilitated maintaining controlling conducive for optimal cultivation.
