Gravity: Analog Turbidity Sensor for Arduino / ESP32 / STM32 / Raspberry Pi (ADC Required) | Water Quality Monitor | <500ms Response Time & 0-4000NTU Range

Description

Product Overview

The Gravity Analog Turbidity Sensor is a reliable water quality monitoring tool designed for use with Arduino, ESP32, STM32, and Raspberry Pi platforms. It measures turbidity levels from 0 to 4000NTU with a fast response time of less than 500ms, making it suitable for real-time water quality analysis. The sensor features dual signal output — analog (0-4.5V) and digital (High/Low) — allowing flexible integration into various projects. Built for durability and ease of use, it is ideal for environmental science, wastewater treatment, and sediment transport research.

Usage

This sensor is perfect for field applications such as river and stream monitoring, wastewater effluent testing, and laboratory water quality control. It is also suitable for educational projects and DIY environmental monitoring setups. The sensor is designed for use in controlled environments and should not be fully submerged. Place the small round head of the probe into the water for accurate readings.
