Logbook

This is your logbook. Insert here all relevant information regarding the evolution of your project

In this week we started to get to know each other. We were also assigned to a group and started to think and choose one of the projects. We made the dicision that we will work on the Level/Weight Monitoring System for a Waste Oil Storage Tank.

In this week we started to search for information about the project we will be working on.We also had some group meetings. We worked on the following points.

• Search for sensors, gsm/gps modul,
• we had a meeting with Prof. Nidia
• we began to write the report
• we made a first test with the sensor
• we creat our task list and make the gantt chart

This week it was a hard week, because we had a lot of classes so it was difficult to work very good on the project. We got some paper boxes and made a prototype of our container, also we get the key from the company and we looked inside the container. Also we made a second test with our prototype. It still works. After that we searched also for diffrent types of battery and sensors and we think about the communication modul. We also made a marketing index.

In this week we made some tests with the prototype.

We put our prototype box into the container. And we tried to find a solution how to put the box inside the container. We olso worked on the marketing plan and we searched the market for the competitors .

We wrote our midterm report and also we started to made the presentation.

We finished the presentation. And we had the presenation with the supervisors and the other teams.

We searched for more information about the ultrasound system and the battery.

1. Presentation
2. Modus operandi
3. Project proposal
4. Electronic Logbook

1) About the oil tank
2) About the main controller
3) About the sensors
4) Communication 
5) Power source
6) Local interface
7) Data acquisition
8) Container

We have asked some questions about our project and we got some ideas. They gave us some recommendations on how to approach the problem.We also try to explain how we will go on. The supervisors gave as some points to think about. Look at the List below.

• Information about the container (the waste oil is in bottels, there are diffrent typ of containers)
• Study the diffrent types of sensors (range of sensors, communication, price,use one voltage)
• Local interface
• Konfiguration ( because of the diffrent type of containers)
• Think about the logistic
• Load Cells

1) Power supply
2) The problem of the bottles all in one side

In this Meeting we talk about

1.)Power Supply

• make a table of pro an contra, which power supply is better
• Solar Panales, Battery (Low Cell Discharge rate)

2.)Problem with the bottles

• we get the information, that it will be enough to know, that the container is almost full
• We should try to find a local seller for our sensor

3.)Container

• One Option is to design a new container

4.)Materials

• make detailed list of materials we are going to buy

1) About the battery types.
2) About the arduino (atmega) sleep mode and voltage regulator consumption vs atmega standalone chip.
3) About the local interface.
4) Communication shield and pins used.
5) Marketing
6) Web interface

• We should make an item list for the next meeting.
• The arduino mini as an alternative for low power consumption.
• We have to put all information into the drop box

1) Web interface (Advice on some Options like php, cgi, java ? etc )
2) The local interface ( Last meeting we discuss a bit about this, so should we really make a simple local light indicator or just an option for the web interface to get the value which could be accessed by a mobile phone with internet connection for example.)

• Our questions were aswered and we discussed about them.
• We also went through many aspects as the prototype, the 3D computer model.
• We were told to make more detailed task list inside each main task we have.

1) Reciever interface - Communication Program (C++) <-> Gsm PEN.
2) Discussion about the sleep mode -  we thought to use the watchdog but can only sleep.
   maximum of 8sec but many times. Other option would be to use some kind of alarm clock externally.
3) Advice on which program to use for the java web programming.   
4) When should we expect to recieve the materials?
