Hello everyone,
I am making a mobile sensor that measures barometric pressure and temperature and sends it wirelessly through a nano to an uno that logs the data. i want to have several of these sensors sending data to a single uno and am wondering what would be the best wireless hardware to use for this application keeping in mind that it is going to be in a car so i will have metal and glass in the way but it will not be sending data anymore than 10ft. i also want something that is cheap and easy to code 
best case of course but i would prefer easy of use over low cost.
if anyone has any suggestions on what would be my best option let me know thank you.
