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; 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, and

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

2. The system of claim 1, wherein the smartphone further comprises a retrieval unit for retrieving the water quality data stored in the memory unit.

3. The system of claim 1, wherein a water quality standard is stored in the memory unit, and

the smartphone further comprises a comparative determination unit for comparing the standard with the measured water quality data, and 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 standard.

4. The system of claim 1, wherein the smartphone further comprises a recording unit for recording a water quality measurement diary, and the diary of the recording unit is stored in the memory unit.

5. The system of claim 2, wherein the smartphone further comprises a recording unit for recording a water quality measurement diary, and the diary of the recording unit is stored in the memory unit.

6. The system of claim 3, wherein the smartphone further comprises a recording unit for recording a water quality measurement diary, and the diary of the recording unit is stored in the memory unit.
