1. A measurement circuit of a body weight measuring apparatus comprising:
a load sensing unit comprising at least one wheatstone bridge circuit configured to generate a load information comprising at least one of: a left-side weight, a right-side weight, an anterior-side weight, and a posterior-side weight, in the form of an output voltage, upon application of a load on the body weight measuring apparatus, wherein the load sensing unit is powered by an input excitation voltage across the at least one wheatstone bridge circuit;
an amplifier circuit operatively coupled to the load sensing unit and configured to receive the output voltage and amplify the output voltage to generate an amplified output;
an analog to digital converter circuit operatively coupled to the amplifier circuit for converting the amplified output to a digital representation of the weight of the load;
a microcontroller operatively coupled to the analog to digital converter and configured to receive the digital representation of the weight of the load and transmit the digital representation of the weight of the load to a server for computing an exact weight of the load, wherein the microcontroller is configured to calibrate and read the analog to digital converter to receive the digital representation of the weight of the load;
wherein the microcontroller is further configured to receive a sway configuration information from the server and generate a score indicative of the load swaying and transmit the score to the server, and wherein the score is processed by the server to determine a statistical information associated with a sway of the load on the body weight measuring apparatus, the statistical information comprising at least one of a mean, a variance, a skew, and a kurtosis, and wherein score indicative of the load swaying on the scale is generated upon enabling and configuring a sway function on the server by a user, wherein the microcontroller is configured to receive the sway configuration information during each instance of connection with the server.
