A sensor produces the sensor data for a sensor data consumer. A device receives a sensor profile of the sensor indicating a relationship between a sensor parameter operating range and a deviation of the sensor data as a result of scaling one or more sensor parameters. The device receives a tolerance profile of the sensor data consumer indicating a tolerable degree of deviation of the sensor data and scales a parameter of the sensor according to the tolerance profile. The scaling reduces a power dissipation level of the sensor.

Method and apparatus for reducing sensor power dissipation

A communication system receives a binary sequence from a sensor, identifies a power consuming characteristic of the binary sequence, and determines an error component configured to reduce the power consuming characteristic of the binary sequence. The system compares the error component to an error tolerance deviation, and if the error component is below the error tolerance deviation, combines the error component with the binary sequence to produce an output sequence and transmits the output sequence via a serial interface to a receiver configured to receive the output sequence. The error threshold is based in part on an error tolerance characteristic of the receiver.

System, method, and apparatus for reducing power dissipation of sensor data for bit-serial communication

A sensor produces the sensor data for a sensor data consumer. A facility receives a sensor profile of the sensor indicating a relationship between a sensor parameter operating range and a deviation of the sensor data as a result of scaling one or more sensor parameters. The facility receives a tolerance profile of the sensor data consumer indicating a tolerable degree of deviation of the sensor data and scales a parameter of the sensor according to the tolerance profile. The scaling reduces a power dissipation level of the sensor.
