schematic diagram of my first pcb board

Hello all,

I am doing a project where I have to design a PCB. I am new in this 
field. I am using EAGLE PCB software.



About my project: I am working on a project where I have to measure the 
environments temperature. I am using TI's CC2541 Bluetooth soc, temp 
sensor TMP102, DC DC convertor, SOC debug flash TSW-105-02-S-Q and 
MURATA's Balun transformer. Whenever I put the battery in my PCB, the 
temp sensor reads the data and send it to my phone via Bluetooth. For 
this PCB design I am using eagle software. Since I am new to this 
software and I am working alone in this project I want help from you 
all.



Till now I have the schematic design on software. I am attaching my pdf 
file here, so you guys check the file and tell me if I am going in a 
right direction or not?

And also how to check the design if it is correct or not? I clicked on 
the error button, it is showing warnings only not an error.

guys can you help me with this?
