What is a Water Quality Sensor?

A water quality sensor is a type of device used to measure and monitor parameters of water quality. These sensors that can read the physical, chemical and biological attributes of water. Water quality sensors are indispensable for assessing the water resources, maintaining human health and protecting aquatic habitat.

Some of Common Parameters That Water Quality Sensors Can Measure Include:

pH: A measure of the acidity or alkalinity of water, which is crucial for aquatic life and various industrial processes.

Dissolved Oxygen (DO): The amount of oxygen dissolved in water, which is vital for the survival of aquatic organisms.

Turbidity: A measure of the clarity of water, indicating the presence of suspended particles. High turbidity can be a sign of pollution or runoff.

Conductivity: A measure of the water's ability to conduct an electric current, which can indicate the presence of dissolved salts and minerals.

Temperature: Water temperature can affect the solubility of gases and the metabolic rates of aquatic organisms.

Total Dissolved Solids (TDS): The combined content of all inorganic and organic substances dissolved in water.

Biochemical Oxygen Demand (BOD): An indication of the amount of biodegradable organic matter in water, which can deplete oxygen levels.

Chemical Oxygen Demand (COD): A measure of the amount of organic matter that can be chemically oxidized in water.

Nitrate and Phosphate Levels: Important for assessing nutrient pollution, which can lead to eutrophication.

Bacteriological Quality: The presence of bacteria such as E. coli or coliforms, which can indicate fecal contamination and pose health risks.
