Abstract
An electro-optic liquid sensor may include a light source, a light detector, a prism, and a reflective optical member. The optical member may be arranged to reflect light emitted by the light source to the light detector when a liquid is disposed between the light source and the optical member. The electro-optic sensor may enable assessment of its operational state in the presence of liquid, thus improving on known electro-optic liquid sensors. A method of operating a sensor to assess the presence of liquid is disclosed.
