Turbidity Sensor Module

The Turbidity Sensor Module is a water quality sensor designed to measure the turbidity or cloudiness of water by detecting the amount of light scattered by suspended particles. It provides an analog voltage output that varies with the concentration of suspended solids, making it ideal for monitoring water purity in aquariums, wastewater systems, environmental monitoring, and DIY smart water quality projects.

Using infrared light, this module allows real-time detection of changes in water clarity and can be easily integrated with Arduino, ESP8266, ESP32, and other microcontroller platforms.

Key Features:

• Real-Time Turbidity Measurement: Detects changes in water clarity caused by particles like sediment, algae, or pollutants

• Analog and Digital Output: Read water turbidity as an analog voltage or set a threshold for digital output

• Infrared Sensing Technology: Stable, reliable detection using light scattering and transmission

• Onboard Comparator and Potentiometer: Adjustable sensitivity for threshold-based detection

• Easy Integration: Plug-and-play with common microcontrollers via analog or digital pin

Specifications:

• Operating Voltage: 5V DC

• Current Consumption: ~30 mA

• Output:

  • Analog: Voltage proportional to turbidity level

  • Digital: HIGH/LOW based on threshold set by onboard potentiometer

• Measurement Range: 0 – 1000 NTU (Nephelometric Turbidity Units, approx.)

• Detection Method: Infrared light scattering

• Waterproof Sensor Head: Submersible and safe for continuous water contact

• Cable Length: ~100 cm

• Module Dimensions: Approx. 35mm x 25mm

Applications:

• Water quality monitoring (aquariums, ponds, tanks)

• Environmental sensing and pollution detection

• Smart agriculture and irrigation systems

• Laboratory and educational experiments

• DIY water purification and filtration systems

This sensor module is a reliable, affordable, and easy-to-use tool for monitoring the cleanliness of water in a wide range of real-world applications.
