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

on .

Lozano 00


   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.

Registration for the EN 13725 Interlaboratory Comparison 2018 is open

on .

ILC2018    The Interlaboratory Comparison for Olfactometry (ILC) based on the Standard EN 13725:2003 has been announced for this year 2018 and once again the company Olfasense is behind the organization. The registration period has started!

   The EN 13725 interlaboratory test gives odour laboratories all around the world the opportunity to demonstrate compliance with their performance requirements and compare the performance of any laboratory internationally. Once year again, the ILC 2018 will be carried out in June, but all interested to participate must register before April 27th.

Urban experiences in the management of odors on Wastewater Treatment Plants

on .

sauco   The generation of odours in a WWTP is usually caused by the presence of hydrogen sulphide (H2S). This gas, moreover, is responsible for the deterioration of the facilities’ materials and involves a health hazard for plant operators. Currently there are several alternatives that allow decreasing the impact of odours associated with H2S.

   This paper presents some techniques focused on management of odours in WWTPs as a result of the experience of DAM as WWTP Manager: experiences of removal of H2S in collectors, deodorization of a WWTP by the injection of confined air in the anoxic biological reactor of the sludge line, studies at pilot scale for the application of a TECNIUM’s biofilter percolator, a photo-ionization for the treatment of air streams, and ozone plus ultrasound for the treatment of liquid streams.
