I am a Mechanical Engineer and I work with custom automation solutions in the south of Brazil. I need a programmer with good knowledge on ESP programming and MySQL Databases. And some experience on Android App development. This project is about using an ESP8266 to measure 2 load cells and store data into a cloud service (like AWS) mySQL database. The hardware consist of: 1ESP8266 + 2 load cells (HX711 Modules), 2 LEDs and 1 button. I will provide the schematics. The ESP Code has to: Use ARDUINO IDE. Automatically create and stores a unique serial code. Must be able to connect to new Wifi networks using a system similar to the WifiManager library. Use a secure connection to the database https. Have a process to calibrate the load cells, using Serial Communication inputs. Continuously monitor the load cells and save any changes in loads (beyond noise) to the database with a timestamp. As the following example Serial Date Time Cell1 Cell2 999999999999 30/01/2020 13:33:33:333 9999 3333 The data base must be able to handle several ESPs feeding data into it from different networks. I don't have much experience on databases, so I need your expertise to help defining the right cloud services and tools needed to reach the project goals. The next step of the project will be an android app that uses this data, so to demonstrate the feasibility we would like to have a sample app, that can be made even in MITs App Inventor. The app has to be able to access and show the data stored by any ESP.

Hell, you can have your own server with SSL for cheap plan from Hostinger, that's where I create PHP file to receive data from your ESP over HTTPS I create MySQL script on server side to log the received data into a database tables and yes with time stamps I design app with MIT app inventor to fetch this data from online table straight to displayed on your app the project becomes more versatile if you had your own server and don't worry take care of the back-end part, not to mention the ESP-8266 with HX711 actually i made a WiFi based app that monitors weigh sensor data in 30m over WiFi from 4 nodes on LAN based on ESP with this app [login to view URL] and this one is environmental monitoring system that logs sensor data ie: humidity, temperature, tVOC, CO2,particulate matters and noise onto web server MySQL, and user retrieves (in real time) all of them from here [login to view URL] i am guru in programming ESPs, PHP, MySQL as well as font-end, in all IoT projects

@ITECH

Hi There, We have studied the project requirements. It will be pleasure for us to develop working prototype of the circuit. We will recommend to use ordinary web server for data posting and database management, acquiring cloud at this stage will be expensive. Once the prototype has been tested and validated you ca opt for cloud. We will do the cloud part as well as Android app. Please feel free to contact us. Best Regards, Shahbaz.

@WaleedKhader

Hello, My name is Waleed and I'm a Mechatronics Engineer. I have been working with Arduino since four years. I also had worked with SQL and I know how to design a database and update its data. Also, I had used MIT app inventor before so I think I will be able to design the app using MIT app inventor. First, I will make sure that the esp8266 send data to the server, then I will connect the load cells, then I will make the app. You can check my reviews.

Hi, I have experience doing projects like this, Using service AWS, Firebase, MySql and others. If I right understood you need: 1) Connect a controller to WiFI(Hardcode IP, SmartConnect or captive portal ) 2) Save data to service AWS or Firebase or MySql 3) Using standard API firebase or AWS or native android build application for checking data
