Our NDT-module is low cost, low power, reconfigurable, and reliable solution to monitor the thickness of
materials, structures, or equipments while in operation. The NDT-module works in conjunction with our Sprouts
platform as an attachable external module to one of four module-ports. The NDT-module communicates with
Sprouts via custom designed PnP protocol over a standard SPI-bus. The system architecture of the NDT-module is
depicted in Figure 2.
