Embedded Systems & IoT Intern - Sarada Technologies

(2025-01 - 2025-03)

• Solar Panel Cleaning Robot: Designed full LoRa-based wireless control firmware on STM32; autonomous cleaning logic eliminated 100% of manual field intervention across 200m+ range.
• Smart Energy Management System: Built current-sensing firmware with relay actuation; logged energy consumption data over UART to a monitoring dashboard, reducing audit effort by ~50%.
• Address Scanner (RPi 5 + Camera): Deployed OCR pipeline on Raspberry Pi 5 with camera module for automated address recognition with real-time output.
• Implemented UART, SPI, I²C, and LoRa protocols; performed PCB assembly, circuit testing, and hardware debugging across 10+ boards.
