A novel miniaturized and battery operated electronic nose (60x60 mm) for measuring different odorouscompounds is presented in this paper. It can be connected with any smart device or personal computerthrough a Bluetooth link, which is used for commands and measurement data exchange based on a simpleprotocol. The system is controlled by a high performance 8-bit microcontroller and includes four miniaturizedmetal oxide (MOX) sensors for odour detection, an integrated sensor for temperature and humiditymeasurement, and the appropriate signal conditioning circuits.
