Hello.Can anyone help me producing a problem statement and a market research for a project? The project is an electrical fingerprint door made with a Raspberry Pi 4 B, a fingerprint scanner module, a magnetic sensor to make sure that when the door closes the door get locked and a camera. I have some difficulty in writing in perfect english, maybe anyone could help me with my problem statement and market research. I can give an example of a problem statement in my work. If anyone could help me I would be very glad.

These have to have at least 500/700 min words - 1200/1500 max words.

Example of an project made before but this one is a smart pet feeder:

1 Problem Statement

Nowadays, owning a pet(s) in a home or apartment is a very common reality , a reality representing 67% of the U.S households, or about, 85 million families according to the National Pets Survey conducted by the American Pet Products Association (APPA), but not an easy one as the owner carries the responsibility and obligation of feeding them, as well as taking good care of them. Therefore, for them it is mandatory that, at any part of the day, they will have to be at home to prepare a meal for their animal(s) in order to keep them in a healthy meal plan regardless of all their appointments and tasks during the day that could be rather important.

As so, we only see 2 possible solutions to deal with this inconvenient problem: 1. Buy a cheap pet food dispenser; This option relies on the owner to be at home and portion the food or on the animals self-control, requiring educational skills from the owner for his specific pet, otherwise it can gorge as much food as it wants, which could lead to serious health issues. It also results in greater costs of food expenses. 2. Buy an auto-feeder; The auto-feeders already existing in the market are an expen sive option and, mostly, do not include a user control from another device, acquiring little data about their food habits nor meeting the concerns about the pet habit specification.

This grows a need for a smart pet feeder: A device that would be remotely controlled, letting the user feed each specific pet, through recognition technology, the right amount of food at the right time, as well as create feeding routines and getting the infos on the pets feeding habits helping to prevent serious health problems.

3 System Analysis

Considering the problem, we need to separate the technologies required into entities , that allow the system to work,to analyze them individually into greater detail and observe their connections in a big picture.

Therefore, there are 6 subsystems that we must consider for the system which are: The Mobile Application, the Main System , the The actuators, The Sensors , The Database and Web.

The user is the agent that will configure the system(STM32) with the Mobile Appli cation , being the interface between the user and the system via Web. The inputs of the system besides the user interaction through the mobile application, will be the load sensors to measure the food in the corresponding bowl, the proximity sensor for the user to know the % of filled container for each container, and the RFID sensor to detect the animal near the system deciding for the system whether to put food in the bowl and to open the bowl cover or not, as the outputs of the system. The data of the pet interaction with the system will be then stored in a databases that the user will have the content shown in the mobile application.
