Langelier Index for Water Monitoring for Smart IoT PaaS

Implement Langelier Index for Water Monitoring using Open Source IoT PaaS

Langelier Index (LI) is used as an indicator for corrosivity of water. It measures the ability of water to dissolve or deposit calcium carbonate.

• Conductivity, for TDS (Total Dissolved Solids) determination

• pH
• Temperature
• Total Alkalinity
• Ca Hardness

The Langelier Saturation Index is a calculation used to determine the adequacy of the pool or spa water chemistry, as it relates to corrosion and scale formation. The adjustment of the pH, total alkalinity or calcium hardness can be used to adjust the Langelier Index so that it falls within the ideal range.


Currently, Langelier Index is calculated based on manual test results obtained using Electrodes and reagent, based on Hach method 8073.


Using IoT Gateway we can calculate Langelier Index using sensors to obtain the data from swimming pools for Smart City Infrastructure.


In our project, we propose to build a KIT to measure Langelier Index to assist Municipalities, to monitor Swimming Pools and similar water resources 
and future planning.

Langelier Water Index Gateway Kit based on Open Source will greatly benefit countries in Africa Sub Continent and help United Nations to blockchain the information for Water Management resource and future planning.


Langelier Water Index Gateway Kit can be sold to Smart City Municipalities, at a reasonable cost.
