The 29-year-old man, identified only as Erdal E, worked as a cleaner at the tented refugee camp in Nizip in the southern Gaziantep province near the Syrian border.
He was found guilty of sexually abusing eight children in the camp's toilets in exchange for payments of between 1.5 and five Turkish lira (USD 0.50-USD 1.70/0.45-1.50 euros), the Dogan news agency said.
His defence had asked for his acquittal, saying an earlier confession to police had been made under duress.
The camp, which is home to some 10,800 refugees, has been visited by international dignitaries and is adjacent to the Nizip container camp for Syrian refugees which was visited by German Chancellor Angela Merkel in April.
During the trial, the accused claimed he had been made a "scapegoat" to cover up the crimes of others and prevent a wider scandal.
"I know very well the names of many managers and camp workers guilty of abuse... But I will not say them so as not to hurt my own family," the Hurriyet daily quoted him as saying.
A team from the Gaziantep chamber of doctors visited the Nizip camp in the wake of the scandal, drawing up a report which sounded the alarm over sexual abuse and the risk of sexually-transmitted diseases at the camp.
Chairman Hamza Agca said there were problems with abuse of women and children, as well as early marriage and polygamy.
"We are worried about the risk of sexually-transmitted diseases due to the high rate of polygamy and early marriage at the camp as well as abuse of children," he said last month, according to the chamber's website.
He requested information about the prevalence of sexually-transmitted diseases at the camp and what action was being taken to stop child abuse and child marriage.
"Do you think that marrying at between 7 and 15 years has a negative effect on a child's health?" he asked.
