Working principle
The water quality detector is a water quality testing instrument that calculates the content of the corresponding components in the water through electrochemical reaction or chemical reaction, colorimetry, titration, conductivity measurement, etc.
Portable electronic water quality detector mostly use the electrode method to detect each measurement index, which is composed of MCU, display panel, supporting sensor module, battery, etc. The principle is to use various sensors to collect water quality parameters, and display the sample after data processing. concentration value.
Solution
Using the DWIN T5L0 chip as the control center of the whole water quality detection display, by the temperature collection, pH measurement, dissolved oxygen, turbidity, TDS detection module for water quality data collection to calculate the corresponding sample concentration value, which drives 5.0 inch 800 * 480 resolution LCD panel to display the test results, and through the wireless Bluetooth module to achieve networking and cloud data transmission, supports micro-printer to print the test results on site. It can be widely used in sewage engineering, industrial smelting, aquaculture and other industries of water quality testing.
Features:
1.Accurate data: 16bit ADC acquisition data is processed based on T5L0 algorithm (dedicated 16bit ADC processor or T5L0-based ADC parallel processing can be selected), separation of analog and digital circuits, strong anti-interference capability;
2.Rich functions: support pH, dissolved oxygen, conductivity, turbidity, ORP parameter measurement indexes at will with simultaneous detection and fast response.;
3.It can store 30,000 measurement data, set up to 100 measurement curve parameters, and support historical data query;
4.Support data acquisition and analysis software, USB interface data export, and data upload to the cloud, remote update;
5.Support external portable thermal printer, which can print the measurement results quickly on site.
6.Intelligent interactive design, user-friendly.
