Title:
IOT-BASED GROUNDWATER MONITORING SYSTEM USING LIDAR SENSOR TECHNOLOGY
Document Type and Number:
WIPO Patent Application WO/2021/172719
Kind Code:
A1
Abstract:
The present invention relates to an IoT-based groundwater monitoring system in which a lidar sensor measurement device equipped with a lidar sensor and a GPS sensor is provided on the upper side of a ground well, so as to store and manage geographic information about the location thereof and real-time groundwater level change data. The groundwater monitoring system, using water level measurement, according to the present invention comprises: a GPS sensor unit which records location information by using a satellite signal; a measurement sensor unit which generates water level information by measuring the level of groundwater by emitting a laser vertically downward; a memory unit which integrates and stores the generated location information and water level information as one data value; a communication unit which transmits the stored data value to the outside; and a power supply unit which supplies power for operating the lidar sensor measurement device.
