What happened to Hopper at the end of Stranger Things season 1?

Hopper made a mysterious deal with the government forces behind Dr Brenner's lab, in which he gave up Eleven's location to save Will from the Upside Down. However, when the agents arrived at the school, Eleven was battling the Demogorgon. She disappeared into thin air upon vanquishing the beast.

As Hopper left the hospital where Will was recovering, a government agent pulled up and ushered him into a car, and he was driven off to an unknown location. Then, a month later, after leaving a Christmas party, he returned to the woods and placed some Eggo waffles in a mysterious box, presumably for Eleven.
