User how to make an Outlet that is an IoT-connected outlet with an integrated energy meter to track individual EV charging session data to automatically manage the payment between the property owners and the users through an app.

I am seeking a freelancer to develop an IoT-connected outlet with an integrated energy meter for a project involving commercial property owners. The main goal of this project is to create a seamless payment process for EV charging sessions. I need the actual prototype. Key Requirements: - Create an outlet that is IoT-connected and equipped with an energy meter - Develop an app that allows users to track individual EV charging session data - Implement a payment system that automatically manages the payment between property owners and users - Ensure accurate tracking of charging session data Ideal Skills and Experience: - Experience in IoT development and integration - Proficiency in app development for both iOS and Android platforms - Knowledge of energy management and metering systems - Familiarity with payment gateway integration - Understanding of EV charging infrastructure and protocols Project Scope: - The estimated number of EV charging sessions per day is less than 10 - The target users for this IoT-connected outlet are commercial property owners - The main focus of this project is to create a seamless payment process for the charging sessions 1. **Hardware:** - **Current Sensor:** Use a current sensor to measure the flow of electricity to the EV charger. - **Voltage Sensor:** Measure the voltage to calculate power consumption. - **Microcontroller:** A microcontroller (e.g., Arduino, Raspberry Pi) to process sensor data. - **Communication Module:** For sending data to the app (e.g., Wi-Fi, Bluetooth, GSM, LoRa). - **Power Supply:** Provide a stable power source for the smart meter. 2. **Software:** - **Embedded Software:** Write firmware for the microcontroller to read sensor data and process it. - **Communication Protocol:** Implement a communication protocol for data exchange between the smart meter and the app. - **App Development:** Create a mobile or web app to receive and display the energy consumption data. 3. **Integration:** - **Sensor Integration:** Connect current and voltage sensors to the microcontroller. - **Communication Integration:** Integrate the communication module with the microcontroller. - **App Integration:** Implement the communication protocol in the app to receive and display the data. Step-by-Step Guide: 1. **Sensor Integration:** - Connect the current sensor to measure the current flowing through the EV charger. - Connect the voltage sensor to measure the voltage across the charger. 2. **Microcontroller Setup:** - Program the microcontroller to read data from the sensors. - Calculate power consumption using the formula: Power = Voltage × Current. 3. **Communication Module Integration:** - Connect the communication module to the microcontroller. - Program the microcontroller to send energy consumption data to the app using the chosen communication protocol. 4. **App Development:** - Design and develop a mobile or web app to receive and display energy consumption data. - Implement the communication protocol on the app side to receive data from the smart meter. 5. **User Authentication and Security:** - Implement secure user authentication in the app to ensure only authorized users can access the data. - Implement encryption for data transmitted between the smart meter and the app. 6. **Testing:** - Test the entire system in a controlled environment to ensure accurate data transmission and display. 7. **Deployment:** - Install the smart meter in the desired location. - Make the app available for download and use. We are looking for a freelancer who can deliver a reliable and efficient solution that meets the requirements of commercial property owners and ensures a smooth payment process for EV charging sessions.
