The Gravity: Analog Turbidity Sensor for Arduino (SEN0189) is a high-performance turbidity sensor designed to detect water turbidity by measuring light transmittance and scattering caused by suspended particles in water. As the concentration of total suspended solids (TSS) increases, the turbidity level rises—allowing this water quality sensor to provide real-time feedback on water quality for environmental monitoring. This turbidity sensor supports both analog and digital output modes, giving users flexibility based on microcontroller compatibility. With an adjustable threshold in digital mode, it is ideal for a wide range of Arduino-based water monitoring projects and automated water quality sensor applications. Key Features Dual output modes: Analog (0–4.5V) and Digital (High/Low) turbidity sensor signals. Adjustable threshold in digital mode via onboard potentiometer for custom water quality sensor triggers. Fast response time: Less than 500ms for real-time turbidity monitoring. Detects TSS-based turbidity using light scattering and transmittance as a reliable Arduino sensor. Compatible with Arduino and Gravity IO Expansion Shields for easy water monitoring setup. Easy to integrate into automated water quality monitoring systems and hydroponics control. Applications River and stream water quality monitoring and turbidity analysis. Wastewater and effluent analysis using accurate water quality sensor data. Sediment transport research with TSS-based water monitoring. Aquaculture and water purification systems involving Arduino sensor integration. Laboratory liquid experiments for precise turbidity sensor measurements. Note: The top of the sensor probe is not waterproof—avoid submersion of the entire water monitoring probe. Specifications Operating Voltage: 5V DC Operating Current: Max 40mA Response Time:
