Wireless sensor networks Zigbee applied on sewage treatment station
The good efficiency in a sewage treatment plant (WWTP) is a great importance to the environment. The management of electromechanical equipment installed in these stations is a major challenge due to the fact that they are ...
Desenvolvimento de instrumentação eletrônica portátil para medida de pH em campo por meio de sensor óptico à base de filme de Polianilina
(Universidade Federal de São CarlosUFSCarPrograma de Pós-graduação em BiotecnologiaCâmpus São Carlos, 2014-05-30)
The pH measurement has an important role in biotechnological processes as enzymatic reactions, fermentation processes and others. This ways the general objective of this work is therefore the development of a portable ...
Sensor Fusion with Low-Grade Inertial Sensors and Odometer to Estimate Geodetic Coordinates in Environments without GPS Signal
This paper presents a sensor fusion algorithm based on a Kalman Filter to estimate geodetic coordinates and reconstruct a car test trajectory in environments where there is no GPS signal. The sensor fusion algorithm is ...
Measuring air pressure with a polymeric gas sensor
(Sociedade Brasileira de Química, 2010)
In this communication we describe the application of a conductive polymer gas sensor as an air pressure sensor. The device consists of a thin doped poly(4'-hexyloxy-2,5-biphenylene ethylene) (PHBPE) film deposited on an ...
