DFRobot Gravity Analogue Turbidity Sensor

The DFRobot Gravity Analogue Turbidity Sensor is an Arduino-compatible module designed to detect water quality by precisely measuring turbidity levels. It functions by analysing the light transmittance and scattering rate within a liquid sample, which changes proportionally with the amount of Total Suspended Solids (TSS). As TSS concentration increases, the turbidity level rises, and this sensor provides accurate readings to monitor this key water quality parameter.

This versatile sensor offers both analogue and digital output modes, providing flexibility for various project requirements. The digital output mode features a high/low level signal, with an onboard potentiometer for easily adjusting the detection threshold. Engineered for reliability, it operates on a standard 5V DC supply with a maximum current draw of 40mA and boasts a rapid response time of less than 500ms. Its robust design supports an operating temperature range of 5°C to 90°C, making it suitable for a wide array of environments and applications.

Key Features & Applications

• Dual Output Modes: Offers both analogue and digital signal outputs for versatile data acquisition and simple threshold detection.
• Quick Response: Delivers readings in under 500 milliseconds for real-time monitoring.
• Easy Integration: Compatible with the DFRobot Gravity interface and Arduino boards like the UNO R3, allowing for plug-and-play connectivity without complex soldering.
• Adjustable Sensitivity: The integrated potentiometer allows for fine-tuning of the digital output trigger point.

Ideal for embedded system design, electronics prototyping, Internet of Things (IoT) projects, and educational hobbies, this sensor is a fundamental tool for anyone developing water monitoring systems, environmental sensing stations, or smart aquarium controllers.
