My project is a device that allows you to monitor a pet at home through a website. It has various ways to interact with your pet. The first is a camera which when turned on displays the video feed from a camera. The second is a speaker which has two functionalities: play song and play frequency. This allows you to get the attention of your pet. The pet monitor also tracks data that is useful for pet owners. This includes temperature, last time your pet was fed, and last time your pet was let outside. All of these features make this device a great way to observe and interact with pets at home while away.
There is not much hardware for this project. There are three devices that need to be connected to the Beagle Bone: the camera, the speaker, and the TMP101 sensor. The speaker input port connects to P9_14. The TMP101 sensor connects P9_21 for SCL and P9_22 for SDA. The camera is a PlayStation 3 Eye which is USB camera, so it connects to the USB port on the Beagle Bone. For more information on the camera visit: https://en.wikipedia.org/wiki/PlayStation_Eye.
Give step by step instructions on how to install your project.
- Include your github path as a link like this to the read-only git site: https://github.com/MarkAYoder/gitLearn.
- Be sure your README.md is includes an up-to-date and clear description of your project so that someone who comes across you git repository can quickly learn what you did and how they can reproduce it.
- Include a Makefile for your code if using C.
- Include any additional packages installed via apt. Include install.sh and setup.sh files.
- Include kernel mods.
- If there is extra hardware needed, include links to where it can be obtained.
Once everything is installed, the program can be ran by executing the following commands:
bone$ sudo ./setup.sh bone$ sudo ./httpMonitor.py
Once the application is running, open yourLocalHost:434 in a web browser to view the monitor. The variable yourLocalHost should be the same IP address used to open cloud9. This number is 192.168.7.2 for me. So, to open the Pet Moniter I search 192.168.7.2:434 in my web browser. On the website, there are many buttons that control the pet monitor. A table is included below describing their functionality | Button | Functionality | | Camera | Toggles the camera. When turned on, the website will pause for a second while the video loads then display the stream. When turned off, the stream should turn off will little delay| | Speaker at frequency | When turned on, the speaker will play the frequency at the specified frequency which can be changed. When turned off the speaker will stop making sound |
This project has many cool features including:
- Visually appealing HTML/CSS website
- Animated HTML/CSS buttons
- Speaker that can play a melody (Old McDonald)
- Speaker that can produce a frequency given by the input attribute on the HTML/CSS
- Camera that can be started/killed directly from the website
- TMP101 sensors that read temperature when the page is refreshed
- Data for time since let out and fed that are updated when the page is refreshed
Include a YouTube demo the audio description.
Theory of Operation
Give a high level overview of the structure of your software. Are you using GStreamer? Show a diagram of the pipeline. Are you running multiple tasks? Show what they do and how they interact.
- Created Flask page
- Used Motion to stream from camera
- Added the ability to start and stop camera stream using animated button from website
- Adjusted size of displayed camera stream on the website
- Added a speaker that can play a song as well as a specified frequency
- Developed an interface to speaker on website- this includes two animated buttons and one user input
- Attached TMP101 sensor that updates temperature on website upon any refresh
- Included time since last meal and time since let out displays that can be updated upon corresponding button press
- Added refresh button with animation
- Edited Website so that it is visually appealing
- Figured out how to use ngrok to publicly stream the Pet Monitor website
If I had more time to work on this project, I would use SSH tunneling or ngrok to broadcast the pet monitor onto non-local hosts. This would allow access to the website while not being directly connected to the Beagle Bone. At the moment, it is possible to stream using ngrok, but a different website is used each time the program is ran. This is inconvenient and can be improved upon. If I had time to add this feature, I would also want to add a security feature. This would protect the camera feed of your home from being publicly accessible.
Another improvement that could be added is to use Blynk to create a web app that works in parallel with current website. In the beginning stages of the project I was able to stream from the camera to a Blynk app on my phone. However, the quality was horrible so I switched to making a website. If the quality issues could be resolved, a user could access the pet monitor from both a web browser and an app on their phone.
Aside from these two, smaller features could be added to the project as well. For example, more songs could be added to the play song feature or an alarm could go off if time since last fed is greater then a certain threshold.
Give some concluding thoughts about the project. Suggest some future additions that could make it even more interesting.
