Electronic Nose and Its Applications. Freshness of fruits and vegetables

      Аннотация: The book includes five important steps in the designing and development first, to design odour detection gas sensor array, second is the development of a single sample fruit chamber, third is the organization of multiple samples fruit chamber, fourth is to develop a wireless data transmission and reception and fifth, the software part for displaying appropriate results and data analysis. The developed system is divided into two sections, one is hardware section and other is software section. Here two conditions were introduced; wired and wireless data transmission. In the wired transmission, collected data or the output of the sensor is directly send to the PC or laptop through the arduino using a VISA tool. On the other hand, when the system is wireless data transmission electronic nose (WEN) system, XBee module is introduced for the wireless data transmission.
