You should use a combination of light sensing and oil pressure not just one thing to make sure its more accurate sensing behaviour.

I expect those sensors be (extreme?) expensive. Although maybe some poisons can be detected easily, it is very hard to be sure that no others are in, and that would give people the illusion the water is save.

Yes I think so...The sensors are pretty costly but maybe one set of sensors per village can be enough and just what we need if I'm able to devise a system wherein all the various water sources spread accross the village can be tested as one single point, with various sources being closed and open to test at one time and to know which one source has what all characterics!!

Well anytype of purity level is good for them because these people already have 62 mentally impaired kids back in 150 homes in a single village and the elders are in addition to this so ,whatever good we do adds to the total solution, but yeah! we need to be like try to solve as much as we can.

about the cost, if the system does some good pollutants gauging and distillation stuff then we can tap the local government to get the systems financed, After all they are also in the radar of this shit because the stuff which whole of the world and India eats is grown there.

Hey rob,

I was previously suggested by a Physicist to use the optical spectrum to look for each and every minute small bateria/virus/metal/elements in it, I'm not sure what you think about this?

I'm looking for deducing Arsenic, pesticides, insecticides and other metals constituency in water and soil.

Lil bit of background:

 recently there's been a very high increase in cancer and mental impairment in children with Blue baby syndrome in some nearby places, people have been found with pesticides in their blood!
The water they drink is a vicious poisnous cocktail!
 So what I'm trying to do is first deduce that what all sorts of pollutants are there in the water and if possible soil too and then devise a remedy to cure them.
Seeking advice on tackling both the above cases.

Good stuff sir!

If there are any test leads/connection sockets left out on the PCB board which I think would be there if they really want to do some debugging then you can tap onto the data but still you have to see to it that what sort of a protocol is used there!

it took many hours, and wasn't really worth the effort smiley-grin

I back this point.

Generally I think you will learn a lot-lot more if you try to make a keyboard of your own with you own PCB and tactile or whatever buttons you like rather than trying to hack such whacko.

Whats this MS project? (MicroSoft Project!?? some sort of a app like excell, access or word?)

i need to control my object by using the accelerometer that detect the change in distance in 3-axis " X,Y,Z" by detect acceleration.
All 3axis accelerometers do that! whats the big deal? are you asking that you want to use a accelerometer but donot know which accelerometer to buy, then goto sparkfuns accelerometer buying guide.

The adafruit website lists that any wallwart adapter from 5v to 12v will do and also the USB socket can be used to charge ,so both of these 2 different options makes us looking at a minimum voltage threshold of 4.5 to 5.5vdc (depends on pc to pc hardware on usb output voltage) meaning that the board works with at least a minimum of 5vdc input to charge the single cell lipos.

Well try on its good for your academic development OR else there are folks who can do this!
