-Figure shows the general schematics for the electronic measurement board developed.
-We have developed a complete "plug and play" measurement board. To measure electrical resistivity with Raspberry Pi.
-two ADS1115 were used,one for the voltage measurement one for the current measurement, as proposed by Florsch [7]. The ADS1115
-is a 16-bit ADC (Analog-to-Digital Converter), with an adaptable gain. The advantage of ADS1115 is that the
-input signal value could lie between - to + 6.114 V. For the current measurement we have directly integrated the INA282 component,
-which allows to realize precise current measurement around a shunt resistor. The assembly steps are described in the following steps:
