Product Details
Turbidity Sensor Suspended Turbidity Value Detection Module Kit
The Turbidity Sensor Module Kit is a cost-effective and reliable solution for measuring water cloudiness and evaluating overall water quality. Turbidity is a critical parameter that indicates the presence of Total Suspended Solids (TSS) such as clay, silt, organic matter, algae, and microorganisms.
This sensor operates on an optical measurement principle using an infrared LED and photodetector. As light passes through the liquid, suspended particles scatter the light, causing changes in intensity that are converted into an electrical signal. The module provides both a precise analog voltage output for continuous turbidity measurement and a configurable digital output that triggers when turbidity exceeds a user-defined threshold set via an onboard potentiometer.
🔧 Key Features
- Measurement Function: Detects water turbidity caused by suspended particles using optical sensing.
- Dual Output: Provides analog output (0–4.5V) for detailed measurement and digital output for threshold-based detection.
- Microcontroller Friendly: Designed to work seamlessly with 5V DC platforms such as Arduino, PIC, and AVR.
- Adjustable Threshold: Onboard potentiometer allows easy configuration of the digital trigger point.
- Fast Response: Response time of less than 500 ms for near real-time monitoring.
- Robust Optical Design: Uses an infrared LED and photodetector for reliable, non-contact liquid measurement.
💡 Applications
- Washing Machines and Dishwashers for water contamination detection.
- Environmental Monitoring of rivers, lakes, and water bodies.
- Aquaculture and Hydroponics water quality control.
- Educational and Research Projects related to water analysis.
- IoT-based Water Quality Monitoring Systems.
