Abstract: In some examples, a liquid container comprises a chamber forming a volume containing a liquid, an elongated strip extending into the volume containing the liquid, a plurality of heaters supported by the strip along the strip, and a plurality of temperature sensors supported by the strip along the strip. The temperature sensors output signals indicative of dissipation of heat from the heaters to indicate a level of the liquid in the volume.

Abstract: A print component integrated circuitry package includes a number of temperature sensors where each of the plurality of the temperature sensors is disposed in a corresponding temperature region of an integrated circuitry. In an example, an analog sense bus conductively connects to all of the plurality of temperature sensors and an external sensor pad that is to connect to a corresponding print controller contact.

Abstract: In one example a liquid level sensor is described. The sensor includes a carrier and a liquid level sensing interface disposed on the carrier. The liquid level sensing interface includes a number of liquid level sensing devices disposed on an elongated strip. The number of liquid level sensing devices detect a liquid level in a liquid container. The liquid level sensing interface also includes a number of thermal isolation components formed on the elongated strip to thermally isolate adjacent liquid level sensing devices.

Abstract: In some examples, a liquid container comprises a chamber forming a volume containing a liquid, an elongated strip extending into the volume containing the liquid, the strip supported along a side of the volume such that a face of the strip adjacent the side of the volume is not opposed by the liquid, a plurality of heaters supported by the strip along the strip, and a plurality of temperature sensors supported by the strip along the strip.

Abstract: Examples provide a series of heaters supported at different depths within the volume. A series of temperature sensors is supported at different depths within the volume. The temperature sensors output signals indicative of dissipation of heat from the heaters to indicate a level of the liquid within the volume.
