The pharmaceutical industry mandates strict hygiene and sterilization practices, particularly in cleanroom laundry environments. Manual processes for validating wash formulas often fall short in ensuring consistency, regulatory compliance, and safety. This paper presents the design and implementation of an IoT-based chemo-thermal disinfection monitoring system for pharmaceutical laundry operations. The system employs industrial-grade pH and temperature sensors connected via RS485 Modbus to an ESP32 microcontroller. Data is processed and transmitted to a cloud server using MQTT, allowing real-time monitoring through the Blynk platform. The system includes a water circulation mechanism to ensure accurate sampling and has been rigorously tested under harsh environmental conditions. Results demonstrate significant improvements in measurement accuracy, process transparency, and operational efficiency. This approach exemplifies the convergence of Industry 4.0 and hygiene-critical operations, providing a scalable model for smart industrial laundry automation
