A breather including desiccant for humidity control includes an electronic end of life detection system. A temperature sensor and humidity sensor provide a temperature and humidity of the desiccant to a controller. The controller determines the relative humidity of the desiccant. The controller determines that the desiccant, and thus breather, has reached its end of life (i.e., end of useful life) when the relative humidity reaches a predetermined relative humidity (e.g., 40%). Optionally, a pressure sensor provides a pressure of the reservoir to the controller. The controller determines a fault condition or end of life condition of the breather when the pressure exceeds a predetermined pressure.
