   A new miniaturized electronic nose (60x60 mm) connected to a smartphone through Bluetooth connection that was presented in this conference has an electronic design similar to other prototypes, but with a smaller size and consumption. The control of the system is based on a microcontroller PIC18F46K80. It includes four miniaturized MOX sensors and an integrated sensor of ambient temperature and humidity with suitable conditioning circuits.

   Communications with the smartphone are made using a Low Power Bluetooth Transmitter. An Android application has also been developed to connect to the device and to monitor the measurements. Data processing is performed remotely on a server by sending a request to it and subsequently receiving the output value of a classifier based on neural networks or fuzzy logic calculated on the server.

Abstract

   We present in this communication a new miniaturized electronic nose (60x60 mm) connected to a smartphone through Bluetooth connection. The device presented here has an electronic design similar to other prototypes, but with a smaller size and consumption. The control of the system is based on a microcontroller PIC18F46K80. It includes four miniaturized MOX sensors and an integrated sensor of ambient temperature and humidity with suitable conditioning circuits.

   Communications with the smartphone are made using a Low Power Bluetooth Transmitter. An Android application has also been developed to connect to the device and to monitor the measurements. Data processing is performed remotely on a server by sending a request to it and subsequently receiving the output value of a classifier based on neural networks or fuzzy logic calculated on the server.
