• Voltage sensors (voltage dividers for 0-60V)
• Current sensors (Hall-effect: ACS712 or similar)
• Solid-state relays (60V, 40A minimum)
• MOSFET PWM controllers
• Electromagnetic brake (wind turbine)

• Raspberry Pi: ADS1115 I2C ADC module
• Arduino: Arduino Mega 2560 (for sufficient I/O)
• ESP32: ESP32 DevKit V1 or similar

See DEPLOYMENT.md for complete hardware specifications.

⚠️ This system controls potentially dangerous equipment

• High voltage electricity (48V+)
• Rotating machinery (wind turbine)
• Fire risk from electrical faults

Always:

• Follow local electrical codes
• Use proper safety equipment
• Test thoroughly before deployment
• Implement mechanical fail-safes
• Have professional inspection for production use
