Narrative:

The captain was flying and I was performing PNF duties. At approximately the outer marker while running the landing checklist; we received the 'pitot 3 inoperative' EICAS message. The message went away and came back at about 500 ft. During this time we noticed a hot or burning smell. After the nosewheel touched down; the flight attendant notified us of smoke in the cabin. We exited the runway; notified the tower we needed to evacuate and proceeded to evacuate. The evacuation was completed in approximately 90 seconds with no injuries to the crew or passenger.callback conversation with reporter revealed the following information: the reporter stated the airplane was an embraer 145 and on approach; the crew observed the 'pitot 3 inoperative' EICAS message at the outer marker and again at 500 ft. The reporter did note a hot or burning smell but no smoke. On landing; the cabin attendant then reported smoke in the cabin. After clearing the runway; the crew stopped the airplane; declared an emergency and began emergency evacuation of the passenger. The reporter; first officer; exited the cockpit and looking aft into the cabin could only see half way down the cabin due to smoke. The reporter's duty during the evacuation was to assist the passenger out and away from the aircraft. Fire crew and maintenance removed the cockpit top right sidewall covering at the cockpit bulkhead and found burned and scorched wiring.
