PSR stands for PHP Standards Recommendations, this is a code convention. Magento 2 uses PSR-1 and PSR-2 See https://www.php-fig.org/psr/ for the conventions and examples.

An example is that you should write methods in camelCase and not with underscores, for example:

public function my_method()

 // do something

Should be:

public function myMethod()

 // do something
