The working principle of STEVAL-IDI003V2 involves a few steps that can be broken down as follows:

1. First, a strain gauging element is fitted onto the surface of a structure or object such as a bridge or roof with any change in the dimension of the certain surface due to strain or load, the strain gauging element also changes its electrical resistance.
2. The strain gauging element is connected to the STEVAL-IDI003V2 strain-gauge amplifier, and the amplifier amplifies the signal of the gauging element.
3. The amplified signal is forwarded to the STEVAL-IDI003V2 strain-gauge controller, which performs 3x signal conditioning. This is done to remove any errors from the amplified signal received from the amplifier.
4. The conditioned signal is then sent to a processor, which interprets the data and shows it in the form of values and figures.

By using this principle, the STEVAL-IDI003V2 evaluation board helps in delivering accurate and fast evaluation of strain-gauge sensors and in understanding the dynamic and static behavior of the strain-gauge sensors.
