Abstract: The technology relates to keeping sensors of a perception system optically clear and free from condensation. A transparent film, such as Indium Tin Oxide (ITO), acts as a moisture sensor that covers the optical area of interest. When a measured value of the moisture sensor meets a certain threshold that indicates the presence of condensate, power is applied to the sensor, turning it into a heater. When the measured value no longer meets the threshold, power is removed and heating ceases. The ITO layer may be lithographically applied to a glass sensor cover or other window, with interleaved sections of material that are spaced closely to detect a minimum amount of condensate. This arrangement enables the system to be employed in sensor assemblies at various locations along a self-driving vehicle, and can be used with different types of sensors such as lidar sensors, cameras and other imaging devices.
