The 12V air pump (flow rate of 2–3.2 l per minute) was controlled by the Raspberry Pi (on and off) and either powered by a 5V GPIO pin or separate battery power, with subsequent voltage conversion using a custom circuit. The PiGas-Direct and PiGas-Pumped had a 12,000 mAh 3.7V ...
For crack growth monitoring, the ADNS-3080 receives the command from the Arduino UNO to capture images. The captured images are then sent to the Arduino UNO and are processed with the DSM algorithm to calculate 2D displacements. After the calculation, the results are transmitted wirelessly through...
