         3 . The dishwasher appliance of  claim 1 , wherein the controller comprises a memory, the plurality of transfer functions stored within the memory of the controller. 
     
     
         4 . The dishwasher appliance of  claim 1 , wherein the sensor comprises one of a temperature sensor, a turbidity sensor, a pressure sensor, and a humidity sensor. 
     
     
         5 . The dishwasher appliance of  claim 4 , wherein each of the temperature sensor, the turbidity sensor, the pressure sensor, and the humidity sensor comprise a respective output. 
     
     
         6 . The dishwasher appliance of  claim 5 , wherein each of the respective output of each of the temperature sensor, the turbidity sensor, the pressure sensor, and the humidity sensor comprises a respective range of outputs for one of the plurality of transfer functions. 
     
     
         7 . A dishwasher appliance, comprising:
 a cabinet;   a sensor disposed in the cabinet;   a controller in signal communication with the sensor, the controller configured to,
 receive an output of a sensor, and 
 select one of a plurality of transfer functions for the sensor in response to the output of the sensor, 
 wherein each of the plurality of transfer functions is associated with a respective one of a plurality of sensor types. 
   
     
     
         8 . The appliance of  claim 7 , wherein the output of the sensor comprises at least one of frequency and voltage. 
     
     
         9 . The appliance of  claim 7 , wherein the controller comprises a memory, the plurality of transfer functions stored within the memory of the controller. 
     
     
         10 . The appliance of  claim 7 , wherein the sensor comprises one of a temperature sensor, a turbidity sensor, a pressure sensor, and a humidity sensor. 
     
     
         11 . The appliance of  claim 10 , wherein each of the temperature sensor, the turbidity sensor, the pressure sensor, and the humidity sensor comprise a respective output. 
     
     
         12 . The appliance of  claim 11 , wherein each of the respective output of each of the temperature sensor, the turbidity sensor, the pressure sensor, and the humidity sensor comprises a respective range of outputs for one of the plurality of transfer functions. 
     
     
         13 . A method of operating a dishwasher appliance, comprising:
 receiving, at a controller of the dishwasher appliance, an output of a sensor;   selecting, by the controller, one of a plurality of transfer functions for the sensor in response to the output of the sensor,   wherein each of the plurality of transfer functions is associated with a respective one of a plurality of sensor types.   
     
     
         14 . The method of  claim 13 , wherein the output of the sensor comprises at least one of frequency and voltage. 
     
     
         15 . The method of  claim 13 , wherein the controller comprises a memory, the plurality of transfer functions stored within the memory of the controller. 
     
     
         16 . The method of  claim 13 , wherein the sensor comprises one of a temperature sensor, a turbidity sensor, a pressure sensor, and a humidity sensor. 
     
     
         17 . The method of  claim 16 , wherein each of the temperature sensor, the turbidity sensor, the pressure sensor, and the humidity sensor comprise a respective output. 
     
     
         18 . The method of  claim 17 , wherein each of the respective output of each of the temperature sensor, the turbidity sensor, the pressure sensor, and the humidity sensor comprises a respective range of outputs for one of the plurality of transfer functions.
