Short summary
In this paper we present a new Arduino-based wire extensometer developed to provide a low-cost autonomous platform for continuous monitoring of landslides. The system integrates a data logger, a power system, a high-precision position transducer, and has multiple digital and analog inputs. Our field test indicates a high reliability of the measurement and high monitoring stability without visible thermal drift. The on-board temperature sensor might be used to correct/identify thermal drifting.
