Water Turbidity Sensor Module Kit – Analog & Digital Output

Explore water clarity with this Water Turbidity Sensor Module Kit. Designed to detect suspended particles through changes in light transmission, this 5V sensor provides analog and digital outputs for DIY electronics, Arduino experiments and water-monitoring projects.

Compare clear and cloudy water, read the analog signal with a microcontroller, or adjust the onboard potentiometer to trigger a digital signal at your chosen threshold.

Key Features

• Optical turbidity detection: Monitors changes in light transmission caused by suspended particles in water.
• Analog output: Provides a 0–4.5V signal for sampling with a suitable analog-to-digital converter.
• Digital output: Provides a high/low signal with an adjustable trigger threshold.
• Adjustable sensitivity: Onboard potentiometer lets you tune the digital switching point.
• Microcontroller projects: Suitable for Arduino, AVR and PIC projects with compatible input circuitry. Raspberry Pi projects require a suitable external ADC for analog readings.

Technical Specifications

• Operating voltage: 5V DC
• Maximum working current: 40mA
• Response time: less than 500ms
• Analog output: 0–4.5V
• Digital output: high/low level, adjustable threshold
• Insulation resistance: minimum 100MΩ
• Specified operating temperature: -20°C to 90°C

Project Applications

Use the kit for educational water-clarity experiments, tank-monitoring prototypes and suspended-particle detection projects. Its optical signal helps you observe relative changes in turbidity.

Package Includes

• 1 × turbidity sensor with module
• 1 × connecting cable

Important: Turbidity readings do not establish whether water is safe to drink. Check voltage compatibility before connecting the outputs to your controller. Calibrated turbidity values require an appropriate calibration procedure.
