Description
Product Overview
The Gravity analog turbidity sensor module by MidzooMod is engineered for precise measurement of water clarity. Featuring a high‑quality optical sensor head, the unit converts light scattering into an analog voltage output, enabling accurate turbidity detection across a wide range. Housed in a durable ABS enclosure, the module includes a built‑in temperature compensation circuit and a standard 3.3 V/5 V power interface, making it compatible with most microcontroller platforms. Detailed specifications such as measurement range (0‑4000 NTU), resolution (0.1 NTU), and response time (under 1 second) are provided in the datasheet, ensuring developers can integrate the sensor confidently into their projects.
Usage
This sensor excels in both laboratory and field environments. In a lab setting, it can be connected to a benchtop data acquisition system for continuous monitoring of water samples during experiments. Outdoors, the rugged housing protects the optics from splashes and dust, allowing deployment in rivers, lakes, or industrial wastewater streams. Ideal users include environmental scientists, water treatment engineers, and hobbyists building DIY water quality stations.

FAQ
What is the output type of the sensor?
The module provides an analog voltage proportional to turbidity, typically 0–5 V, which can be read by any ADC input.
Can the sensor be used in salty or chemically aggressive water?
The ABS enclosure protects the optics, but for highly corrosive environments we recommend adding a protective mesh or using a dedicated marine‑grade housing.
Is calibration required before first use?
Each unit is calibrated at the factory; however, for critical applications you may perform a quick two‑point calibration using a clear water sample and a standard turbidity solution.
What power supply voltage does the module accept?
The sensor operates from 3.3 V or 5 V, making it compatible with most development boards.
How does temperature affect the readings?
Temperature compensation circuitry minimizes drift, keeping accuracy within ±2 % across the specified temperature range.
