Executive Summary

Hardware


In the Project we are using a 7” LED Touch panel to display sensor data and control outputs. Sensor data that will be displayed on the screen include two independent temperature measurements. The data will be displayed in number and through a graph. For monitoring the temperature behavior over time. Additionally, the 12V battery voltage will be measured and displayed. The GUI include Buttons to control a one channel relay to switch on led Lights.

The two 3V relays can provide 12 V and 10A power output.

The two TMP 101 temperature sensor are used to measure indoor and outdoor temperature.

Three demo buttons on the LCD screen can be pressed to switch the 12V Power. This can control the heating or ventilation system or simply used to turn on 12V LEDs to light up your camper.

Indoor and outdoor temperature values are monitored on the screen. An additional menu allows to set specific times to switch the relays autonomously. This allows for example to switch off the water pump during the night.

The project is located on GitHub here: [1]

In the Github repository, you will find a README file with all necessary installation.

Assembly

Hardware built

The very first step was to screw all hardware components on a 6mm acrylic plate with three levels. The bottom layer consists of two relays, step-down converter, two TMP101 sensors and beagle bone black. We are only using one 12 Volt 1.25A power supply input to provide the necessary power for the hole system. The second layer contains two board one for the HDMI converter the other is necessary to interface the touchscreen.


After the prototype was complete we started writing python test scripts to read sensor data and print temperature values on the Screen. RV Timer wide-3.jpg

For demonstration purpose we are powering a 12 Volt car audio transmitter

User Instructions

Once everything is installed, how do you use the program? Give details here, so if you have a long user manual, link to it here. RV Timer wide 1.jpg

The three main functionalities on the GUI (left to right)

  • The black box displays the timer which triggers the Relay remotely at a specific time. One press on the black box opens a menu to set the timer with a visual keyboard on the screen
  • Underneath are the two outdoor and indoor temperature values displayed in Celcius
  • The button block consists of three direct executable buttons which switch the relays

Highlights

Here is where you brag about what your project can do.

Include a YouTube demo the audio description.

Theory of Operation

For our communication we used Slack. Slack is a open source cloud-based messenger service. Additional our Milestone plan shows our time

Work Breakdown

For our Project, we separated the work-tasks in 3 packages.

Package 1 ( Daniel Patzer)

- Prototype design and Hardware selection 
- relay control with button interface 

Package 2 ( Marius Schwab)

- Software development
  --> clock function, clock alarm
  --> temperature reading of 2 sensors
- implementation in GUI

Package 3 (Vinzenz Felder)

- GUI design
- GUI programming (implementation of GUI function, etc.)
- documentation

Future Work

  • This prototype enables further ioT functionally to get used in your camper. For example by adding a 3G module temperature values could get reported to a google sheet.
  • PID Controller can be implemented to control the heater by setting a specific temperature value.
  • implementing LED dimmer to adjust the brightness of the indoor roof LEDs
  • Controlling the relays through a IOS or android app

Conclusions

This project is still just a prototype. For a real implementation, additional functions should be integrated:
