Abstract

Ammonia is a colorless, water-soluble, and reactive gas with a pungent suffocating odor. Furthermore, ammonia is also produced naturally from decomposition of organic matter, including plants and animals. Once chicken meat going through spoilage process, the ammonia content will be released from it. It is not high content of ammonia, it just low content of ammonia within range at 0 to 10 part per million (ppm). Since it is low content of ammonia, the consumers difficult to differentiate by sniffing the pungent suffocating odor which one the chicken meat was actually in spoilage process. This project come out with a portable nose for detecting the presence of ammonia gas released from the spoilage of chicken meat. The device was designed according to user friendly and portable. To detect the content of ammonia gas released, the device is embedded with MQ135 ammonia sensor because of its rapid response time and low ammonia content range between 0 – 100 ppm. Besides, data processing for this project comprised Arduino UNO board, which consists of ATmega328 microcontroller. It was programmed to sense the presence of ammonia gases.
