Turbidity Sensor Module Kit – High-Precision Liquid Clarity Testing Sensor for Arduino, Water Quality Monitoring, and Smart Home Automation

Product Description

The Turbidity Sensor Module is an advanced electronic water quality testing kit designed to accurately measure the cloudiness or clarity of any liquid. It operates using an infrared transmitter and receiver to detect light scattering and transmittance caused by total suspended solids (TSS). As impurities like mud or debris increase in the liquid, the light transmittance decreases, providing a precise measurement of water dirtiness. This sensor is a versatile tool for automated monitoring projects, ranging from smart aquarium filters to optimising rinse cycles in industrial washing machines.

Detailed Key Features

• Dual Signal Versatility: The conversion board provides both an Analogue (A) output for high-precision data logging and a Digital (D) output for simple threshold-based trigger detection.

• Onboard Sensitivity Calibration: Includes a built-in potentiometer (trimmer) to adjust the digital trigger point, allowing you to customise the turbidity level at which the sensor sends a signal.

• Stable IR Measurement: Utilizes an 880nm infrared light source to minimize interference from surrounding visible light, ensuring reliable and stable readings in various lighting conditions.

• Modular Safety Design: The sensing probe is separated from the electronics by a 3-pin cable, enabling you to submerge the probe while keeping the sensitive control board safely housed in a dry enclosure.

• Power Efficient: Designed for standard 5V logic systems with low current consumption, making it perfectly suited for continuous monitoring in battery-powered IoT stations.

Technical Specification in Details

• Analogue Performance: Delivers a linear output between 0V and 4.5V; higher voltage readings indicate clearer water, while lower voltages represent higher turbidity.

• High-Speed Detection: Features a response time of less than 500ms, enabling real-time monitoring of fluid clarity changes.

• Industrial Resistance: Maintains an insulation resistance of at least 100MΩ, ensuring electrical safety and signal integrity during submerged operation.

• Compact Form Factor: The probe measures approximately 30mm x 20mm x 12mm, with a total kit weight of roughly 30 grams for easy integration into tight spaces.

• Thermal Range: Fully functional in liquid temperatures from 5°C to 90°C, suitable for most domestic and industrial water applications.
