Operational control by o-sensors to prevent complaints

le .

Zorich imagen   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.

Development of personal Electronic Nose for Smartphones for the Measurement of Odours in the Environment

   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.

Thomas Hübert is not with us anymore

   Yesterday, we were informed by the CEN that the 15th on November 2017 Dr. Thomas Hübert passed away after a very short illness. Dr. Thomas Hübert worked at the Federal Institute of Materials Research and Testing (BAM) and he was member of several groups dealing with instrumental odour monitoring such as the Working Group (WG) 41 of the Technical Committee 264 of the CEN.

   Dr. Hübert was activily involved in the WG41 and he was also the coordinator of the German mirror group. The picture on the left was taken in Berlin in August last year, during the last meeting of the WG. Dr. Hübert (in the middle) was a very active person and he took part on many decisions of this group. It is a great loss for his family and friends and also for the "odour" family.
