Bosch BMP085 barometric pressure sensor predicting the likelihood of rainfall - repost


I am creating a Umbrella handle which uses embedded systems and a Bosch BMP085 barometric pressure sensor to predict the likelihood of rain (so without any wireless action or internet). I would like the Sensor to at a press of a button, calculate the likelihood of rain and indicate using an LED, white to show no rain and blue to show rain. Ideally I would prefer the electronics to be powered using a battery. (This is because the housing will be the Umbrella handle).


The projects outcome will involve C++ Programming Coding, PCB building, Circuit Diagram and documented calculations. Also two prototype iterations should be made with the Bosch BMP085 barometric pressure sensor provided. The first prototype 'capturing pressuring' i.e. all the calculations, coding testing. The second prototype should show 'experience' which would in turn show a LED blinking either white or blue depending on the chances of rainfall.

My contributions:

The coding is attached below, please check if you can alter it to meet the brief. And we can meet a suitable payment, as most of the coding (work) has been completed. However, I need the some alterations to be made in the coding to match the brief above. Two Bosch BMP085 barometric pressure sensors will also be supplied to you via post within the payment rate.
