## Overview

The DFRobot Gravity Analog Turbidity Sensor offers rapid, precise measurement of water turbidity by detecting suspended particles through light transmittance and scattering. Compatible with Arduino via a Gravity interface, it supports both analog and digital outputs with adjustable thresholds, making it ideal for environmental monitoring, wastewater treatment, and scientific research. Operating efficiently between 5°C and 90°C, this compact sensor delivers reliable data with a fast sub-500ms response time.

## Description

INTRODUCTION The arduino turbidity sensor detects water quality by measuring level of turbidity. 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. As the TTS increases, the liquid turbidity level increases. This arduino turbidity sensor have both analog and digital signal output modes. You can select the mode according to the MCU as threshold is adjustable in digital signal mode. 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! SPECIFICATION Operating Voltage: 5V DC Operating Current: 40mA (MAX) Response Time: <500ms Insulation Resistance: 100M (Min) Output Method:Analog Analog output: 0-4.5V Digital Output: High/Low level signal (you can adjust the threshold value by adjusting the potentiometer) Operating Temperature: 5℃~90 ℃ Storage Temperature: -10℃~90℃ Weight: 30g Adapter Dimensions: 38*28*10mm/1.5 *1.1*0.4inches SHIPPING LIST Turbidity sensor adapter x1 Turbidity sensor probe x1 Turbidity sensor cable x1 Gravity analog sensor cable x1

Review: Another great sensor - I use loads of sensors and really enjoy building electronic gadgets. I have this connected to and ESP32, with 2 DS18b20 temp sensors, a PH sensor, 2 ultrasonic sensors, light sensors and this turbidity sensor. Purpose, to monitor my pond, and filtration system. There is nothing worse than the pump failing, water levels dropping or rising too high, UV failure - or bad PH levels. Linked up to a dashboard on Blynk i will know exactly whats going on even when I'm not home - once i get it all installed.
Review: good product - good product

## 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.

This is basically the exact same part you'll see in the bottom of your dishwasher, but broken out for generic usage. Device works nice. No complaints, and there's documentation floating around on the internet about it.
