This project presents the design of pocket-sized halal sensor used to detect lard adulteration in oil using dielectric spectroscopy method. This system will feature the application of Interdigitated Electrode (IDE) connected to Analog Devices’ AD5933 Evaluation Board to measure impedance and a mobile app that acts as the User Interface.

The whole system will be connected using Arduino, specifically Arduino Uno and an HC-06 Bluetooth module. The main motivation of the design is to provide a portable, real-time and accurate lard measurement device which is quite scarce in the market.

Besides that, this project will also focus on the performance of dielectric spectroscopy in detecting lard adulteration. Lard adulteration will be measured using the system designed and the sensor’s performance is measured via FAVORIOT IoT Platform.

Physically, the system consists of the following components:

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.
