Iot Based Smart Supermarket

Iot Based Smart Supermarket

Proposed work depicts the working of the RFID detection system attached to trolleys. Android application for online processing and cash payment is developed. Which is presented in this section.

The proposed system is as shown in figure 3.1. This IOT based Trolley has the application such as Automatic billing at shopping mall and helps to owners. The Sequence of operations is indicated with dotted line and sequence number. The sequence number details are as follows. Supermarket Billing System Mobile Application

1 Power supply:

First initialize the power of the module using battery i.e. 12v, then it is ready to use for the customer.

2 RFID Reader:

Radio frequency identification is unique for every product. It can read 40 tags and it does not require line of sight to read the products. As soon as the product falls in the trolley the RFID reader reads the RFID tag placed on the product. RFID reader is connected to the Pic microcontroller.

3 PIC Microcontroller:

We are using Pic 1846k22 microcontroller. It contains 2 UART and easily we can write the programme. It verifies the information got from the Rfid reader and information in the memory of the microcontroller. Microcontroller is already installed on the cart for data processing and it is connected to Wi-Fi module to communicate with server.

4 LCD Display:

We are using 16×2 LCD display. If the information matches as in the microcontroller then the cost, name and quantity of the product will be displayed on the LCD.

5 Wi-Fi ESP8266:

Wi-Fi ESP8266 is access point that allows the station or client to connect to any router. LCD trolley is provided with Wi-Fi. Here we are creating new website of shopping mall which can transfer the products information to the main server. In order to communicate server and cart we have chosen esp8266 Wi-Fi technology. It is low power and in expensive.

Using android studio, we can develop the application. Using Wi-Fi, a customer can install the application. For a new user, it asks registration details. If a customer has already a member of this application it asks login details. After login, the home page is displayed. In that, we have product information. By searching the products, customer can buy a product. Customer purchased products information is stored in cloud via Wi-Fi module. As soon as customer login to the app, cloud is sent whole product information like number of items, name, price and total amount will be displayed on cart which is present in the app. It asks for the paymentoption, one is cash payment and another one is online payment.

The proposed model consumes less time, low cost and can easily be used by the customer and owner. It does not require any training. RFID helps us to detect the products easily compared to the barcode. Billing is done by automatic in an inventory updated manner. The requirement of manpower will be reduced. Simultaneously we can serve more number of customers https://codeshoppy.com/
