Oversee PCB Design and System Integration

Key Projects I have Completed:

IoT-Based Remote Monitoring Systems: Designed hardware for real-time data logging, GSM/4G communication, and sensor integration.

Industrial IoT Router: Developed custom router PCB with power control, RS485, and Ethernet/VLAN features.

DC-DC Power Supply Units: Designed and tested converters (e.g., 48V to 12V, 12V to 5V) with EMI/EMC considerations.

Battery Management System (BMS): Created multi-cell BMS with safety and protection features.

Transformer Monitoring System: Designed sensor interface and signal conditioning circuits for voltage, temperature, and oil level.

Smart Water Level Controller: Engineered 2-stage water-level detection and motor control using relay drivers.

2x TTL to RS485 & 2x USB to RS485 Converters: Designed isolated communication interfaces with ESD protection.
