Description:
Turbidity Sensor with Module is a device used to measure the cloudiness or haziness of a liquid, typically water. This cloudiness is caused by particles suspended in the water, and turbidity sensors are commonly used in water quality monitoring, aquariums, industrial processes, and environmental testing.Here’s a breakdown of what it is and how it works:
Features:
-
Turbidity Sensor (Probe):
-
Contains an infrared (IR) LED and a photodetector.
-
Measures the scattering of light caused by suspended particles in water.
-
-
Signal Conditioning Module:
-
Interfaces the sensor with microcontrollers (like Arduino, ESP32, Raspberry Pi).
-
Usually has:
-
Analog output (proportional to turbidity)
-
Digital output (often with a threshold adjuster via a potentiometer)
-
Power input (typically 5V)
-
