Build a demo prepaid energy metering system with Arduino or any compatible Atmel microcontroller and a current sensor. Also syncs data to Blynk IoT Cloud platform or to a SD card locally at interval. Code is well commented for easier editing.
Here are the list of modules used in this project:
- Arduino Mega2560 (ATMega2560) or any other compatible Atmel microcontroller.
- LCD 2004 (20 x 4 LCD) for data display.
- 4 x 4 Keypad module for user input and queries.
- SD card module to locally log data.
- ACS712 current sensor to measure current readings.
- SIM800L module for GPRS connection to Blynk Cloud.
