Gravity Analog Turbidity Sensor – 5V Water Quality Module

The Gravity Analog Turbidity Sensor is designed to measure water quality by detecting turbidity levels caused by suspended particles. It operates by analyzing light transmittance and scattering to estimate total suspended solids (TSS) in liquids. The module provides both analog output (0–4.5V) and adjustable digital output for flexible integration with microcontrollers. Built for stable and reliable operation at 5V DC, it is suitable for laboratory testing, environmental monitoring, and wastewater analysis. Ideal for Arduino-based water quality projects and academic research applications.
