Abstract

This invention relates to a system for measuring water quality using a smartphone, and more particularly to a system for measuring water quality using a smartphone, in which, to solve problems of hand-operated and manual water quality measurement methods and in order to increase reliability and accuracy, a water quality meter and a smartphone, which mutually communicate with each other, are utilized, and also, the smartphone is provided with a memory unit, a calculation unit, a GPS unit, etc., thus enabling water quality to be measured in real time and water quality data to be stored and transferred to the outside, so that reliability and accuracy of the measured water quality data may be improved.

Claims

1. A system for measuring water quality, comprising:

a water quality meter having a sensor unit and a transmission unit, wherein the sensor unit includes a sensor for measuring water quality data, and the water quality data includes a potential hydrogen (“

pH”

), a temperature, a dissolved oxygen (“

DO”

) and an electrical conductivity; and

a smartphone, comprising;

a first communication unit corresponding to the transmission unit of the water quality meter,

a calculation unit for calculating data obtained using the water quality meter,

a GPS (Global Positioning System) unit,

a memory unit in which a processing program for the calculation unit is stored and which stores water quality data processed by the calculation unit and GPS information of the GPS unit, a water quality standard being stored in the memory unit,

a second communication unit for sending the water quality data and the GPS information stored in the memory unit to outside,

a retrieval unit for retrieving the water quality data stored in the memory unit,

a comparative determination unit for comparing the water quality standard with the measured water quality data,

an alarm unit for providing a water quality pollution alarm when the comparative determination unit determines that the measured water quality data is greater than the water quality standard, and

a recording unit for recording a water quality measurement diary, the water quality measurement diary of the recording unit being stored in the memory unit.
