3-Phase Pump Control with RFID
Budget: ₹1,500 – ₹12,500 INR
I need a detailed guidance to set up an RFID-based rechargeable electricity system for a 3-phase pump. The system should use an ESP32, LCD display, RFID-RC522, and a single-channel 5V relay module.
Requirements:
- When the RFID card is presented, the system should activate the pump for a limited time based on the balance on the card (e.g., Rs-100 for 100 minutes).
- Balance should be deducted in real-time while the pump is running.
- If the card is removed, the pump should turn off, and the remaining balance should be saved.
- The system should retain the balance even during a power cut.
The freelancer should provide:
- Detailed wiring connections
- Exact code to read/write RFID card balance, control the relay, and display information on the LCD
- Step-by-step instructions for setup
Ideal skills and experience:
- Experience with ESP32 and RFID
- Proficiency in coding for microcontrollers
- Knowledge of electrical systems and wiring
