The main Video of my final outcome..

The 5 Ws

WHY: To raise awareness how much the humankind is surrounded by EMF radiation.


WHAT: It is an EMF detector that senses mobile phone radiation and can also sense objects that have lower Hertz levels as well I.E. Microwave, Lamp, Hair dryer and many more. (To show proof)


WHERE: Everywhere and anywhere.  Simply take it out or indoors and see the world through a different perspective.


WHEN:Anytime. See the difference between an object that is on and off or whilst using the object or not and see the difference within the number of bars.


HOW: Connect the battery and simply see the bars increase or decrease.

OH NO!!!!!!!

An LED EMF detector!

I now enjoyed working with the Arduino, therefore, I wanted to make another type of EMF detector and try out different types of detectors that do the same job. The one I previously made indicated the level of EMF through levels of bars in the bar graph. However, this time I wanted to make an EMF detector that indicated the level of EMF through an single LED light. So;

Bright = High level of EMF radiation level (Run away A.S.A.P and save your life)
Dull = low level of EMF radiation level

IT WORKS!!!!!!

However, the LED light is fuzzy. It doesn't really show a clear understanding of how much radiation there is. Therefore, I prefer to stick with the Bar-graph EMF detector as it shows the level of radiation through clear measurements.

The more I experimented and worked on the Arduino and the programming, the more I began to understand the whole concept and it made more sense.

My survey about radiation.. (I asked people I saw on the streets who were mainly using their phones)

My question;

"Are you aware of the amount of radiation your mobile phone gives out?"

1. The first person I interviewed doesn't care about the radiation but maybe seeing the amount would make her realise how much radiation is actually around her.

2. The second says she is aware of the amount of radiation but needs her phone because she uses for her business but the detector I made would make her realise even more about radiation and therefore she would try and solve this situation by using headphones whilst talking or preferring text rather than calling.

3. The last said she don't believe what to believe about radiation. So my EMF detector would be a proof for her to see the amount of radiation through her own eyes. How harmful it is and maybe she would use her phone lesser.

The reason why I interviewed people is because I began to question my product. So I wanted to see what kind of people would use my product and when? where? How useful would it be? The EMF radiation detector I made would be useful for these people?

Using something different to explore + experiment = learn :D

I was playing around with the Arduino circuit I made that had the bar graph attached. I uploaded the code to work with my bar graph and this time, used the 'Slider'as a means to experiment with the levels of light. When I slide the slider down, the level of light decreases and when I do the opposite it increases.

PHEW!!

ATLAST I managed to make the bar graph light up! The problem was with the wires that was connected to the wrong place in the Arduino and also the coding done for it was wrong so it had to be re-done. After hitting the 'Upload' button the level of bars in the LED bar graph was 0 but as I whent closer to the computers, plugs, light bulb, kettle and microwave it lit and boosted up to 10 bars!!!! AMAZING eh? But the problem is that the EMF detector I made, doesn't really sense the amount of radiation coming out from mobile phones unless if the wire touches the cell phone.

I am still working on this to improve the sensitivity...
