Abstract

Post-drying herbal storage requires precise environmental control to prevent quality degradation and financial loss, making technological intervention critical for local industry partners. To address this issue, an IoT-based control system was implemented using an ESP32 microcontroller, four SHT20 sensors with Modbus RTU communication, a Nextion HMI, and hysteresis-controlled actuators. The service method involved field observation, system integration, actuator assembly (heater and exhaust fan), and user operational training. Testing results showed a 100% success rate across all hardware, HMI interfaces, and real-time web monitoring features. The system successfully stabilized storage conditions within target setpoints (25–27°C and 50–65% RH), boosting operational efficiency and product quality preservation for export readiness at CV. Craftindo Prima.
