Sensor device and method of manufacture and use

A method, comprising:

• receiving, from a sensor device configured as a first shell portion and a second shell portion, when coupled, form single toroid that defines a single aperture, a signal indicative of a voltage associated with a current passing over a line that is disposed through the single aperture of the sensor device;
• receiving, from the sensor device, a signal indicative of (1) a calibrated sensitivity of the sensor device, (2) a calibrated temperature of the sensor device, and (3) an ambient temperature that was received from an ambient temperature sensor;
• defining an actual sensitivity of the sensor device based on (1) the calibrated sensitivity of the sensor device, (2) the calibrated temperature of the sensor device, and (3) the ambient temperature;
• and sending a signal indicative of a modified electric current value based on (1) the voltage and (2) the actual sensitivity of the sensor device.

An apparatus, comprising:

• a measurement module configured to be operatively coupled to sensor device having a first sensor portion and a second sensor portion, the first sensor portion comprising a first shell that includes a first printed circuit board and a second printed circuit board distinct from the first printed circuit board, the first printed circuit board and the second printed circuit board (1) operatively coupled together via a first flexible printed circuit, (2) fully disposed within the first shell, and (3) each include a coil printed thereon, the second sensor portion comprising a second shell and that is configured to be coupled to the first shell of the first sensor portion to define a single aperture, the measurement module operatively coupled to (1) an ambient temperature sensor, and (2) a memory storing a calibrated sensitivity and a calibrated temperature;
• the measurement module configured define a measured electric current value based on a current passing through the aperture of the sensor device, the measurement module configured to output a modified current value based on (1) the measured current value, (2) an actual sensitivity of the sensor device based on the calibrated sensitivity, and (3) an ambient temperature received from the ambient temperature sensor, and the measurement module configured to send a signal configured to cause the sensor device to define a value indicative of a measured electric current, wherein the first shell is semi-toroidal, the second shell is semi toroidal, and the second shell of the second sensor portion is configured to be coupled to the first shell of the first sensor portion to form a single toroid that defines the aperture.
