WSP32 based vending system for washing machines
Budget: ₹1,500 – ₹12,500 INR
RFID based Washing machine & Dryer project.
This project is regarding controlling a commercial washing machine & dryer using rfid technology.
The data of all rfid’s issued will be stored in a database (aws-light sail). When a user swipes the rfid card the terminal, esp32 which is connected to rfid will communicate with webserver & database & will check if the card is present. Depending on the prerequisite conditions, server will send data weather to run the machine or not. If the user has all pre requisites then data base sends communication to run the cycle.

When the server sends data to run machines, then two actions are supposed to happen.
Action 1: Send a square pulse of certain wave length. (Will be recorded from one of our machines)
This will make the machine to run the cycle & complete it.
Action 2: To activate a solid state realy & provide 35 minutes of power supply.
We will use dc control signal SSR. In this case some times the washing machine will not complete the wash cycle in given time, in that case esp32 has to check if the machine is still running at the end of 35 minutes & if running then the power supply must continue for another 5 minutes. If the machine is in off state at 35 minutes then, it need not do anything else.
To know the state of the machine at 35 minutes, we may use current sensor or a vibration sensor .
Components lIst:
1. ESP32 or ESP8266 (https://www.espressif.com/en/products/socs/esp32)
2. RS522 RFID module
3. Buzzer
4. 2.4 inch TFT display (With out touchscreen)
5. Solid state relay
6. Current sensor or vibration sensor.
Will have a battery backup for esp32 so that in case of a power outage, it halts the clock & resumes when power is back.
We are looking for a person to work on embedded coding only, database will be handled by another people.
