Development and experimental calibrations of a multifunction slope monitoring device - Smart Pole

Abstract
Slope failures pose a significant threat to infrastructure and human safety, primarily influenced by factors such as rainfall, surface runoff, changing soil water content, and slope movement. However, most of the existing technologies rely on separate devices with limited integration capabilities. This study addresses these limitations by developing the Smart Pole, a multifunctional slope monitoring device. Equipped with sensors including a rain gauge, humidity and temperature sensor, surface water runoff sensor, camera, soil moisture content sensor, and an Inertial Measurement Unit (IMU), the Smart Pole offers versatility in assembling and disassembling sensors to meet specific monitoring needs. The device incorporates a power supply system and a Microcontroller Unit (MCU) for data collection, processing, and transmission using LoRa technology. This article introduces the purpose, functional requirements, and components of the Smart Pole. Additionally, laboratory calibration and field testing were conducted to validate the Smart Pole's performance. The testing process presents the calibration process of the device's soil water content measurements. The final performance presents the integration of the Smart Pole.
