1 -Mission Statement

Product Description

This product is designed to allow an individual to fully monitor the temperature and humidity of any living space in order to examine his temperature habits as well as optimize his monthly electrical bill.

Benefit Proposition

Our product offers customers to opportunity to save on their electrical bills. With the constant monitoring of temperatures in any room, the user is able to detect wasteful energy consumption as well as mismanaged consumption. This would allow the client to see if there are any problems with insulation, window sealing, or even poor daily habits that result in higher electricity bill such as leaving the heaters on while no one is home. The app monitors any living space, and notifies the user if the temperature of said living space has exceeded the maximum value entered, as well as if it has dipped lower than the minima.

Key Business Goals

The key to our business is for the app to be free with the purchase of a sensor. We are retailing the sensors at 30$ each. Having taken 350 hours to develop, at a rate of 25$/hour, the total cost of the app is 8750$. Therefore, to break eve, we are required to sell 292 sensors. This seems like a very reasonable target. We are attributing 75 hours of work to upgrade and to maintain the app every month. At our labor rate of 25$/hour, this results in an expense of 1875$. The cost to upkeep a server is quoted at 250$ monthly, thus resulting in a total monthly expenditure of 2125$. This would require 71 sensor sells per month, which again is a fairly manageable goal. We are projecting 2500 sensor sales when the final product is delivered, resulting in a gross of 75 000$, which after expenses is a net of 40 750$. Reinvesting the money into the company is our main goal, thus we will be delivering a product with even more features and more functionalities in the near future.

Target Market

Our target market consists of homeowners, landlords and renters. Seeing as the market is very big, we believe we have a plethora of potential customers. Another market that we are targeting is the restaurant market, potentially striking a deal with the Canadian Food Inspection Agency to monitor freezers temperature.

BK-14	Sensor Display	As a user, I want to be able to rename the sensors after adding them and to group them by a group name so that it is easier to find the desired sensor when looking for information.	13	Sprint 2	Sprint 2	I want a nice display of all the sensors and to the ability to group them up. It will be easier to monitor regions of the house that way.	Rename the sensors added. Implement a “create list”-like function where you can select specific sensors and add them to that list.
BK-15	Adding Sensors	As a user, I want to be able to add sensors by their serial numbers so that adding sensors stays a simple activity.	8	Sprint 2	Sprint 2	I want sensors to be added to my account via their serial numbers since it is the easiest way to register the sensors.	Create a registration system for the sensors where you can only register IDs with specific length (the length of the serial number of the sensors). Add them to the list of sensors available.

Temperature is best presented in graph form, since it is easiest to monitor. We will make graphs compatible with the previous time periods discussed.	Create graphing function. Implement graphs for specified times (1 day, 3 days, 7 days, 30 days).
BK-19	Temperature/Humidity swapping	As a user, I want to be able to switch between humidity and temperature readings so that I can monitor both of them within 1 app.	12	Sprint 3	Sprint 3	I want to monitor both humidity and temperature in the app. I don’t want to have to change screens to do so. I want to be able to switch while in the app.	Create a “switch” button that when pressed takes in the “other” data and creates the graphs and live temperature/humidity.
BK-20	Efficiency	As a user I want to see the efficiencey of the heaters in a live view in the Machine State Section so that I know whether or not I need to increase or decrease temperature in order to maximize efficiency.	8	Sprint 3	Sprint 3	Efficiency statistics will allow me to maximize saving money.	??????????
BK-21	Sensor Account Sync	As a user I want to see the sensor information by the name I set them too in registration so that I recognize which sensor is which.	12	Sprint 3	Sprint 3	Link sensor information to the specified account.	When the user adds the sensor to the account and renames it, it should appear in the users account.
BK-22	Data Deletion	As a user I want to be able to close my account and delete all the data the sensors stored so that everything remained private and no memory leak occurs.	12	Sprint 3	Sprint 3	The ability to remove sensors is a feature that is necessary. The deletion of all the data stored from that sensor or just all the data in general is a feature that is critical to this apps success.	Add a function that allows sensor deletion. Prompt use if he is sure that he wants to delete the sensor and all of its data.
BK-23	Calendar Implentation (for graph)	As a user, I want to select a specific date (or an interval) so that I can be able to monitor temperature/humidity change for a given date (or interval)	12	Future	Not in sprint	Implement a calendar feature which lets the user select a date (or an interval) and the display the graph based on that date selected.	Limit calendar intervals (make the start year 2018). Make sure the calendar date translates correctly; 01/02/2018 is January 2 2018 and not February 1 2018. Make sure the selected date format meets the server’s date format.
BK-24	Control Heaters	As a user, I would like to have an option where I can control my heaters through the apps so that I can control them from anywhere and save energy.	25	Future	Not in sprint	Implement the feature on the ESP32 board itself by adding an easy DIY switch that conforms to the public laws. The pins of the board determine the state (touching each other or seperated)	Make sure it works properly. Make sure the ON feature does not act as OFF and vice-versa.
BK-25	Global Notification	As a user, I would like to receive notifications (pop-up or email) if the temperature/humidity of my room drops/rises above a certain value so that I can save time and not check the app constantly.	25	Future	Not in sprint	Implement an email notification system and a pop-up. Let the user choose either or both.	Make sure notifications are refreshed instantly with a slight delay (max 1 minute). Make sure emails can handle fast notifcations for critical purposes.
BK-26	QR/NFC Sensor Add Feature	As a user, I want an easy way to add a sensor so that I would not spend time manually typing the sensor ID.	12	Future	Not in sprint	Implement an easy way to add the sensors; NFC or QR for phones that do not support NFC.	Test the NFC functionality. Make sure the QRs generated are unique.
BK-27	Home Server Setup	As a user, I want to setup the server at my place so that I can have my data under control.	25	Future	Not in sprint	Sell the customer a server (or let him use his own) and ease the setup. This would help reduce the cost and hence the sensor price.	Create a generic server code and make it compatible with different devices.
BK-28	Sensor Brands	As a startup, we want to brand our sensors so that we can advertise our products.	12	Future	Not in sprint	Create a product label for advertising.	Make sure it’s permenant and cannot be removed easily by the customer.
