IoT-Based Electronic Nose for Detecting NPK Nutrients of Chicken Manure

This study focuses on the use of an electronic nose device to monitor the NPK nutrients of chicken manure. With the integration of IoT (internet of things), the data gathered through the e-nose is sent through a mobile application created using Arduino Cloud and Arduino IoT Remote application. The system is composed of multiple sensors such as NPK sensor, moisture sensor, temperature, and humidity sensor in which is used to gather the data significant to the study. The researchers propose the use of such system to aid the user in determining whether the chicken manure is ready to be used or not by observing its nutrient content.
