Hardware & IoT

Custom Hardware & IoT

Bridging the physical and digital worlds with production-grade embedded systems, real-time control, and web-connected dashboards.

We design and build production systems, not prototypes. Every hardware project we deliver is engineered for reliability, maintainability, and real-world operating conditions. From solar energy management to autonomous vehicle navigation, our embedded solutions run 24/7 with web-based monitoring and control.

Solar Inverter Control System

A Raspberry Pi-based controller that manages SunGoldPower and SRNE hybrid solar inverters over Modbus RTU. The system continuously monitors battery state of charge and automatically switches between solar, battery, and grid power modes to maximize efficiency and protect battery health.

  • SOC-based automatic mode switching between solar, battery, and grid
  • Grid failure detection with instant fallback to battery power
  • Weather API integration for predictive energy management
  • Real-time web dashboard with live telemetry and historical charts
  • Comprehensive data logging with SQLite for long-term analysis

Autonomous Lawn Mower Drive System

An ESP32-based BLDC motor controller using the AMT49413 driver IC with closed-loop PI RPM control. The drive system provides precise speed regulation for autonomous navigation across varying terrain, with comprehensive fault detection and a web-based tuning interface.

  • Closed-loop PI RPM control with PWM speed regulation
  • AMT49413 BLDC driver with fault detection and protection
  • Web dashboard for real-time monitoring and PID tuning
  • RTK GPS navigation via Ublox ZED-F9P for centimeter-level accuracy
  • LD06 LiDAR obstacle detection and GY953 compass heading
  • Sabertooth motor controller integration with camera feed
