A Device Design Based on TDS Water Quality Detection

Abstract

The traditional water quality detection method is sampling and detection by artificial nodes, which is easily interfered by weather and environment. The presented design method is a new water quality detection device for marine and other waters. The device is spherical in shape and uses a built-in sensor and control system to detect the water quality in the form of drifting. This device has a built-in micro control system, TDS detection module, power voltage regulator module, GPS module and wireless signal transmission module. The TDS module detects the concentration of total dissolved matter in the water, and the GPS module measures the current location of the device, which sends the data to the micro control system. The micro control system sends the water quality information and the geographical location information through the wireless transmitting module, and the user can view the water quality status by the device in real time through the Internet. The power supply voltage regulator module provides the different voltages required by the entire device to achieve the function of detecting the current water quality.
