The PISA-M in-place MEMS inclinometer is either a uniaxial or biaxial tilt transducer with signal conditioning electronics, housed inside a rugged tube. A set of wheels directs the in-place MEMS inclinometer in the inclinometer casing. Two configurations are possible: the serial-sensor one (basic configuration) or the single-sensor configuration for monitoring a discrete zone. In the first case, only one jumper cable is required to connect the top of the sensor string to the data logger. In the second case, each sensor is connected via its own cable to the data logger. The data from the string of sensors in a borehole provides a vertical profile of the borehole. By comparing profiles over time, deflection and rate of movement can be calculated. The PISA-M can be reused on other projects once the monitoring
