| The site that deals with odour management |
The last 19th and 20th of June, the Working Group 41 dealing with Instrumental Odour Monitoring met in Delft, the Netherlands for a couple of days of intensive discussions. One of the Task Groups (TG) dealing with the minimum requirements for instrumental odour monitoring, presented some interesting points discussed in a previous meeting in Düsseldorf, Germany.
A follow-up discussion was held afterwards on the 11th of July in Gosselies, Belgium.
The use of an appropriate operational management tool plays a fundamental role in establishing and defining the normal operational parameters during any process. If this process also entails a high potential for odor generation or specific gaseous compounds, either due to a specific process condition or deviations from the process, it becomes even more relevant as operational control management. Hence, a detailed knowledge of the processes and levels of odorant gases present must be evaluated based on reliability and accuracy.
This article is based on experience, during the development of a project carried out in a liquid industrial waste treatment plant, and what has been learnt remains current and updated know-how.

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.
