Chris Kennedy/Jackson Sipes Color Sensor – Pipe Sensing

For our project, we were thinking about Public Sewage sensing and how we could use real time analytics to track certain chemicals in the sewage pipes. Currently, waste is only measured using daily processes that analyzes the wasted in a lab. A sewage pipe would have built in sensors that could track certain data about the waste that flows through it, and it could be displayed on a variable screen. We looked at the Color Sensor and how the color of the waste could give information about certain molecules that exist in the waste. We set up a color sensor on a breadboard and then connected it to an LED screen which displays the RGB values. These values could be monitored in realtime and then used to track information about the public in that sewage region.

Cody Smyth Jackson Sipes Soil Sensor/LCD Sensor

For our project, we utilized a soil moisture sensor to measure the water content of different soils and then display the information on the LCD screen. The information will appear based on the analog reading and will tell you if the soil is wet, meaning that you don’t need to water your soil, or that the soil is dry, meaning that you need to add water to the soil. In the video, we use the sensor to test two different soils. The first soil has been sitting in the sun and is very dry, so we expect a low sensing number and the LCD to display “DRY”. The second soil contains much more water volume, so we expect to see a “WET” LCD output with a much larger moisture number. We could compare this to a plant that is placed in soil and needs to be watered each day. Based on the soil moisture sensor reading, you could easily figure out whether the plant needed to be watered or not.

Below is the video of our system testing the two different soils.

Here is the code that we used in order to set up our system:

Jackson Sipes Transistor

In order to implement my transistor, I decided to incorporate a capacitive sensor as the switch that would trigger the heat element of the system. I first mixed the solar dust with some paint and covered a small piece of cloth with the paint. I then wrapped the cloth with some Muscle wire and set up my system so that when the capacitive sensor would hit a certain threshold, it would open the capacitive sensor and heat up the muscle wire. I used an apple as my sensor which I thought was interesting touching an apple to change paint color. Here is a video of my system in action.

Here is the code I used for the system:

Jackson Sipes CapSense

For my project I wanted to test to see if an Apple could utilize a capacitive sensor to trigger a threshold sense and send a signal to the arduino. I set up a capacitive sensor and connected the end of the sensor to the Apple. I then connected the LED I was going to use as a sensor indicator and then mapped it into the code, setting a threshold to trigger the LED when a strong enough signal was sensed by the capacitive sensor. The apple was very conductive and would react very strongly to even the smallest human touch. In this video, you can see how touching the apple will immediately turn the LED on and off.

Here is code that I used for the project. I used a threshold of 1000 to track the conductive sensing.

Jackson Sipes’ Pressure Sensor

For my project I wanted to create a PWM sensor that tracked pressure and could send that information to an LED. I built a pressure system that used two pieces of conductive tape separated by a piece of Velostat. When I would apply pressure to the system, the strength of the pressure would translate to the color of the LED.

Here is a picture of the pressure sensor:

I used an RGB LED that would change from Blue to Green based on the pressure applied to the sensor. The system was very responsive and the pressure strength was easily manipulated.

Here is a video of the system in action:
