WATER QUALITY SENSOR WITHOUT SENSOR TAG WITHOUT USING EXTERNAL ENERGY

摘要

PURPOSE: A water quality sensor node mounted in the river is provided to be operated without a separate external power supply or battery. CONSTITUTION: A water quality sensor node(100) is mounted in the river. The water quality sensor node comprises: a sensor unit(1) which measures water quality in the river and generates a sensor data signal; a control unit(3) which analyzes the sensor data signal and generates sensing information; a communication unit(2) which transmits sensing information; an electric power supply unit(4) comprising a generator which generates electricity based on the power, and a condenser(42) which stores generated electricity. The electric power supply unit supplies the generated electricity to the sensor unit and the communication unit.
