OG exemplary drawing
 
1. A fluid injection device, comprising:
a transducer to output a signal;
a power source;
a temperature sensor to measure a temperature representative of a fluid in the fluid injection device; and
a microcontroller coupled to the power source, the transducer, the temperature sensor, and a memory, the memory including instructions that when executed by the microcontroller causes the fluid injection device to perform operations including:
transition between individual modes included in a plurality of operative modes of the fluid injection device in response to the microcontroller receiving the signal output by the transducer, wherein the plurality of operative modes includes an off state, a power conservation mode, and a high-power mode, and wherein the fluid injection device consumes more power when in the high-power mode relative to when the fluid injection device is in the power conservation mode; and
periodically measure the temperature with the temperature sensor when the fluid injection device is in either of the power conservation mode or the high-power mode, wherein a measurement frequency of the temperature is less during the power conservation mode than the high-power mode.
 
14. At least one non-transitory storage medium that provides instructions that, when executed by a fluid injection device, causes the fluid injection device to perform operations comprising:
transition between individual modes included in a plurality of operative modes of the fluid injection device in response to a signal, wherein the plurality of operative modes includes an off state, a power conservation mode, and a high-power mode, and wherein the fluid injection device consumes more power when in the high-power mode relative to when the fluid injection device is in the power conservation mode; and
periodically measure a temperature representative of a fluid in the fluid injection device when the fluid injection device is in either of the power conservation mode or the high-power mode, wherein a measurement frequency of the temperature is less during the power conservation mode than the high-power mode.
