Low-Cost Sensors Accuracy Study and Enhancement Strategy

Today, low-cost sensors in various civil engineering sectors are gaining the attention of researchers due to their reduced production cost and applicability multiple nodes. Low-cost also have advantage easily connecting microcontrollers such as Arduino. A low-cost, reliable acquisition system based on Arduino technology can further reduce price data monitoring, which make long-term monitoring possible. This paper introduces a wireless Internet-based consisting Raspberry Pi several Arduinos signal conditioners. study investigates beneficial impact similar sensor combinations, aiming improve overall accuracy with an unknown range. The then describes experiment that gives valuable information about standard deviation, distribution functions, error level individual under different environmental circumstances. Unfortunately, these usually missing sometimes assumed numerical studies targeting development structural identification methods. measuring device total 75 contactless ranging connected two (Arduinos) was designed combination theory present deviation functions. include: 25 units HC-SR04 (analog), VL53L0X, VL53L1X (digital).
