Abstract
Provided are a photoelectric sensor and a threshold setting method. The photoelectric sensor is a photoelectric sensor detecting an object and includes a light reception part, an object determination part, and a setting part. The light reception part receives light to obtain a light reception amount. The object determination part determines presence/absence of the object based on the light reception amount and a threshold. The setting part sets the threshold based on the light reception amount during a period in which it has been determined that the object is present and the light reception amount during a period in which it has been determined that the object is absent.
