A print head apparatus capable of temperature sensing is provided. The print head apparatus includes an ink ejector coupled to an enabling signal and a selection signal for selecting the ink ejector. The ink ejector includes a nozzle, a heating module for selectively heating ink in the ink ejector so that ink droplets are ejected from the nozzle, and a temperature sensing module for selectively producing a measured temperature signal indicative of a temperature of the ink in close proximity to the nozzle. When the enabling signal is active, and the selection signal is active and indicates that the ink ejector is selected, the heating module heats up the ink in the ink ejector so that the ink droplets are ejected from the nozzle. When the selection signal is active and indicates that the ink ejector is selected, the temperature sensing module outputs the measured temperature signal indicative of the temperature of the ink in close proximity to the nozzle. By applying the invention to an inkjet print head with a plurality of nozzles, the temperature of each nozzle can be obtained selectively.
