A model circuit (To be developed)
Inspiration
Necessity is the mother of invention. Helping the poor and needy is the happiest thing one can do in their life. In this COVID-19 Pandemic, it is becoming a question of safety to go out and purchase in supermarkets and shops for the customers. This makes everyone prefer online shopping which affects the local small scale vendors the most. Hence many vendors have turned into peddlers and are trying to sell their products door to door. This makes us think about the current effort which would satisfy both the customers and the sellers by fixing the price of the articles with nominal profit, selection of goods by the customers at their own place and even they can fix the purchase timing with the peddlers. Thus, this method would certainly make the retail shop vendors survive in the giant online shopping market.
What it does
The system monitors the vendors passing by the house using motion detection. Motion detection is performed using the PIR Sensor. The PIR sensor identifies the change in infrared radiation of warm-blooded moving objects in its detection range. According to the change in infrared radiation, there will be a change in the voltages generated which was amplified and used to turn on the QR code scanner which scans the QR code placed on the vendor's vehicle. Raspberry pi is to be developed and installed in the kit to scan the QR code, and it will send a notification to the mobile phones using the GSM module. When a vendor comes in the detection range of the PIR sensor, it actuates the QR scanner, the software detects the QR code, it will start to scan and display whatever the vendor has in his vehicle. Once the vendor moves out of the detection range of the sensor, the scanning does not occur. The software repeats the process whenever a vendor visits its place. Thus this will save a lot of manual labour, time and energy.
How it is built
The research aims to design and implement a combination of Passive Infrared Radiation (PIR) based detection kit with Quick Response code (QR) Technology system. The combination of PIR Sensor and QR code reader has plenty of applications such as home security systems, payment technologies, intruder recognition systems, etc. This article utilises the application of a PIR sensor-QR code reader for peddlers sensing and purchase systems. The kit consists of hardware and software parts. The hardware part comprises a PIR sensor that detects the change in infrared radiation of warm-blooded moving objects in its detection range, a QR code scanner to access pre-written content using a raspberry pi camera and a GSM module to communicate to a mobile device. The software part uses Python codes and algorithms for designing the raspberry pi system. The major advantage of the kit is the use of common smartphones for reading the updated items listed. This work will highly be helpful in encouraging the production of local products and its sale. The projected plan will certainly uplift the livelihood of the small scale vendors, disabled persons and also benefit the customers to buy the desired goods at their doorstep with utmost satisfaction.
Risk Assesssment
The peddlers are not used to the hybrid form of connection. This can lead to confusion and may even portray wrong information.
Accomplishments that we're proud of
This can help the needy and overcome the poverty they are facing this period (Pandemic).
What we learned
IoT coding, Interfacing and many other electronic applications can help to build a proper user-friendly system.
What's next for PEDDLER’S MOTION DETECTION KIT WITH QR TECHNOLOGY
An Application(app) can be developed for future endeavours where the peddler/vendors can update the info time-time and can become handy too.
