Water quality sensors employ advanced technology to measure and analyze different characteristics of water. Let's take a closer look at some commonly used sensors and the parameters they monitor:

pH Sensors

pH sensors measure the acidity or alkalinity of water. They utilize a glass electrode that generates a voltage proportional to the hydrogen ion concentration in the water, allowing for accurate pH readings.

Dissolved Oxygen Sensors

Dissolved oxygen sensors determine the amount of oxygen dissolved in water. These sensors typically employ a membrane-covered electrode that measures the oxygen partial pressure, providing insights into the water's oxygen levels, which are crucial for aquatic life.

Turbidity Sensors

Turbidity sensors assess the clarity of water by measuring the amount of suspended particles or solids present. They utilize a light source and a detector to analyze the scattering or absorption of light, indicating the degree of turbidity in the water.

Conductivity Sensors

Conductivity sensors measure the ability of water to conduct electrical currents. This parameter is directly related to the concentration of dissolved ions, providing insights into overall water quality and salinity.

Temperature Sensors

Temperature sensors, as the name suggests, monitor the temperature of water. These sensors play a crucial role in understanding the impact of temperature on aquatic ecosystems and can help identify potential risks, such as thermal pollution.
