This is a reference design of RENESAS TDS Water Quality Tester. The RENESAS TDS Water Quality Tester was converted into DesignSpark PCB format. Download link of the project files and the article of RENESAS TDS Water Quality Tester could be found in the datasheet attachment.
Check water quality and detect hazardous substances in areas such as industrial wastewater, aquariums… etc. By dipping the front part of the device into the water and gently stir to dislodge any bubbles, TDS (Total Dissolved Solids) can be detected immediately. Measured value will display on the LCD monitor and saved by pressing the Hold button for convenient reading and recording. Temperature (°C/°F) can also be displayed by pressing the Temp button. The device includes an auto-off function, which will shut off automatically after 5 minutes without use.
