Project Development

Developed using Arduino, enabling automated regulation of airflow distribution. Implemented four MOSFETs to generate a 0-10VDC control signal, adjusting the speed of Emerson VFDs via PWM (Pulse Width Modulation), each drive was programmed to operate between 0-60Hz, adjusting blower speed dynamically based on received voltage.

Key aspects of the development included:

🔹 Custom Mobile Control Interface – A mobile application was developed to allow users to adjust airflow settings remotely. Commands were sent via a RESTful API, enabling real-time control of the system.

🔹 VFD & PWM Voltage Control – The Arduino controlled four VFDs (Variable Frequency Drives) using MOSFETs to generate a 0-10VDC signal via PWM. The VFDs adjusted blower speeds from 0-60Hz based on this voltage input, optimizing airflow distribution.

🔹 Electrical Schematic Design & Wiring – Designed a complete electrical schematic detailing the integration of all components, including wiring for VFDs, relays, and control circuits. Worked closely with an electrician to ensure correct implementation and safe operation.

🔹 Automated Heat Extraction System – The system efficiently redirected excess heat from underground blowers (located 4 meters below ground) to four key areas: server room, offices, control center, and conference room, using 3” and 4” PVC ducting.

🔹 Efficiency & Facility Optimization – By automating temperature regulation, the system reduced manual adjustments and improved energy efficiency, ensuring stable environmental conditions in critical facility areas.

This structured implementation ensured a reliable, responsive, and energy-efficient cooling solution tailored for critical environments.
