Remote Optical Sensor for Ammonia Detection in Water

Ammonia is a chemical compound that made up of two gases which is nitrogen and hydrogen. Ammonia can be found in several advantages and disadvantages toward human and environment. The advantages of ammonia can be seen from it is very useful that can be used in many industries such as in agriculture, food processing, petroleum, rubber, and other industries. For example, we can see that from agriculture, it is used for livestock feeds, fertilizer, and crop protection. In petroleum, it is used for the protection of equipment to avoid corrosion.

However, during the manufacturing process from industry, there will produce wastewater that contains a concentration of ammonia. When ammonia reacts to water, there are two chemical species exist in water which is in un-ionized form, NH3 and ionized form, NH4. The unionized form is called ammonia whereas ionized form is called ammonium. These two forms which together are called total ammonia nitrogen or in short forms TAN. At the same time, the weak base is formed which means the pH value is greater than 7. It is very important to know that the unionized form is toxic. Therefore, this toxicity will bring negative effect to the environment and may harm aquatic life.

In this project, remote optical sensor towards ammoniacal nitrogen in water will be developed to give an alert if ammoniacal nitrogen is detected in water. For the cloud including the server, database, and the interconnection between it, FAVORIOT IoT platform will be used.
