HI ALL. i'm doing a project on microcontroller,which has to " identify the components (lik nitrogen, phosphorous,...) present in the soil ,by passing some radioactive rays on the sample of soil. whether it s feasible or not?if possible,what type of sensor can be used? if imbossible ,why?
Get your google fired up and feed terms with each of the types of radiation and words like "detect" and "identify" and start reading. There are a huge number of methods that work.
Also read up on the 8051 and ADC converters. Merely detecting things is not enough you need to turn it into a measurement that can be used.
yes, do some googling, for instance, see how the Mars Rovers analyse soil
