## Overview

The DFRobot Gravity Analog Turbidity Sensor offers rapid, precise detection of suspended particles in water by measuring light transmittance and scattering. Compatible with Arduino via a Gravity interface, it supports both analog and adjustable digital outputs, making it ideal for environmental monitoring, wastewater treatment, and scientific research. Lightweight and low power, this sensor delivers professional-grade water quality data with under 1% accuracy—just watch out, the probe tip isn’t waterproof.

## Description

Gravity: Analog Turbidity Sensor for Arduino

## Features

- The arduino turbidity sensor detects water quality by measuring level of turbidity
- It is compatible with Arduino via Gravity interface
- It is able to detect suspended particles in water by measuring the light transmittance and scattering rate which changes with the amount of total suspended solids (TSS) in water
- Turbidity sensors can be used in measurement of water quality in rivers and streams, wastewater and effluent measurements, sediment transport research and laboratory measurements
- Please note that the top of probe is not waterproof

## Questions & Answers

**Q: Every turbidity tester costs $ 250+, so how does this sensor is priced $ 15?**
A: This sensor cannot be used as professional equipment due to the low-precision, you can use it in experimental project and laboratory measurements.

**Q: Is the dac pcb necessary if i just want to use it in analog mode with my arduino?**
A: Yes, you need to simulate the pattern with A

**Q: Does this come with the cable for connecting to arduino?**
A: It comes with a gravity 3-pin female cable, which will be easy to connect to our IO expansion shield, if your arduino is UNO, you still need to use three more male-male jumper wire.

**Q: will this work on 3.3V as well?**
A: No, this analog turbidity sensor needs to operate at 5V.
