The problem Automated Cylinder Monitoring System (ACMS) solves

It's really difficult to keep a track of the volume of LPG gas Right?? .Especially, those guys who cook(in hotels & houses) a lot have encountered a situation where the LPG gas drains suddenly without even knowing. Also many of us have heard about LPG gas leakages which had lead to a massive explosions.At present do the users know about the subsidy status of their cylinder.?No..
What if the module that we are building takes care of all these things for you?
The ACMS helps to monitor the weight, leakage etc.. of the LPG gas cylinder and hence updates the users by giving notification/messages (with the help of IOT technology) regarding the cylinder's health status.The hardware module that we are developing helps to keep a track of the LPG gas usage as well as notifies the user regarding the leakage.We are also adding various security mechanisms to avoid cylinder explosions.The Project that we propose addresses 2 kinds of users.The ones who have an internet connection in their home and others who do not.
The hardware module that we are designing is common for both the users. The app that we are developing will contain the information regarding various booking agencies & Subsidy info of each user by connecting to database of agency .Thus the users can book their cylinder through the app.Users can also enable Automatic booking feature in our system.Notifications will be send to those users who have installed this app.
But wait..What about the users who does not have an access to the internet? The module that we are developing also uses the SMS technology which helps in sending the information regarding the cylinder's weight and Leakage status.We will also provide suitable mechanisms for these users to book their gas cylinder manually. We assure you that our product will be a complete solution for the cylinder monitoring purpose for both the users.Since many of the people and hotels use an LPG gas connection, this product will definitely be a boon for all of them

Challenges we ran into

The loadcell calibration was really one of the challenges that our hardware team came across.It was indeed a tedious task for us.But finally we calibrated the loadcell and it is now perfectly working fine.

The second problem that we ran in to was the database selection for storing the data.At first we decided to use google fire base platform for storing the data.But a strong internet connection was needed for updating values to the firebase.So we switch the database to google sheet. Now we are able to store the data of each user in a seperate google sheet file in a faster manner .We used the IFTTT platform to push the datat to google sheet.

Our module also supports the users who does not have an internet connection in their houses.For that we used SIM800l module for sending SMS.The module is actually a power hungry module.It consumes around 2A of current for sending an SMS.Initiallly it turned on but was not capable of sending messages.But atlast we used a LM2596 regulator to solve the problem.

The App development team faced issues in connecting the google sheet with the app.But atlast they were able to figure out the ways to conect the app to the google sheets and then we successfully updated the values on the app.

We also enquired some of the gas agencies asking about the customers database.Some of them discouraged but some of them told that there are many formalities for sharing the people' database to third party app.So this can be considered as one of the major challenge that we faced on the during our hackathon. We are still trying resolve this challenge.
