The winger agreed a move to Chelsea last week after a summer of speculation linking him with a move to Manchester United.
Pedro had previously been a regular in the Barca line-up under Pep Guardiola, Tito Vilanova and Gerardo Martino, but fell down the pecking order upon Luis Enrique's appointment as coach.
Neymar, Luis Suarez and Lionel Messi were the preferred front three last term and will be again this season, resulting in his decision to exit the club.
However, he will say goodbye to supporters and answer questions from reporters at a press gathering on Monday, before embarking on his new adventure at Stamford Bridge.
A statement on the club's official website read: "Pedro Rodríguez will appear before the press on Monday 24 August at 1.00pm CET.
"The venue will be the press room at the Ciutat Esportiva Joan Gamper.
"Pedro played 321 games for the first team, scoring 99 goals before last Thursday's move to Chelsea."
