Prepaid Energy Meter || GSM Based Project || Automation

Our energy meter operates on the current sensing concept, allowing for precise monitoring of energy consumption. What sets it apart is its prepaid functionality, enabling users to recharge and utilize electricity seamlessly. Recharging is as simple as sending an SMS from your mobile phone, with a unique recharge code provided upon confirmation.

The system features a recharge tag sent via mobile, serving as the recharge code in this prototype. It continuously monitors energy consumption based on load and available recharge balance. Power supply remains active until the recharge amount is depleted.

Dependent on the energy units utilized, this Prepaid Energy Meter kit automatically cuts off power supply after a predetermined unit consumption. Remote operators can conveniently recharge the system via SMS, ensuring uninterrupted power availability.

Equipped with a microcontroller, the system dynamically adjusts power supply based on load fluctuations. When load increases, the relay is deactivated, cutting off power. Conversely, decreased load prompts the controller to reactivate the relay, restoring power.
