Brief Communication: A low cost Arduino®-based wire extensometer for earth flow monitoring

Abstract: Abstract. Continuous monitoring of earth flow displacement is essential for the understanding of the dynamic of the process, its ongoing evolution and to design mitigation measures. Despite its importance, it is not always applicable due to its expensiveness, and the need of integration with additional sensors for monitoring factors controlling movement. To overcome these problems, we developed and tested a low-cost Arduino-based wire-rail extensometer integrating a datalogger, a power system and multiple digi… Show more

“…Positive values correspond to the northern and eastern directions. This instrument was associated to an Arduino-based wire/rail extensometer (tested by Guerriero et al 2017b) consisting of a (i) processing and storage module, (ii) an on-board operating temperature sensor, (iii) a linear position transducer, and (iv) a power unit. The processing and storage modules are an Arduino Uno board and a XD-05 data logging shield, respectively, while the position transducer, responsible for measuring cumulated displacement, is a 1Kohms Bourns 3540S-1-102L precision potentiometer equipped with a pulley of 33 mm in diameter.…”

“…the construction phase (with special attention to the formwork removal process) or also for rehabilitation (velocity of opening of cracks). Also, other applications regarding soil-structure seismic interaction or earth flow monitoring have been proposed [8]. It is worth noting that more usual, expensive devices, seldom allows any interaction with Internet, which might be a very useful capability for in-situ measurements of different magnitudes and their simultaneous management at different sites.…”

“…In this context, recently developed low-cost MEMS accelerometers and other low-cost sensors provide an opportunity to overcome this drawback, also considering that they are particularly suitable for tilt measurement [ 8 ]. In fact, they are being increasingly used in monitoring applications also in association with open-source controlling platforms such as Arduino ® [ 9 , 10 , 11 , 12 ].…”
