The production of low cost sensors to monitor environment in some industrial sectors is a current need. In aviculture centers, for example, the concentration of ammonia gas is related to humidity, and it is necessary to ...

Nanocrystalline WO3/TiO2-based powders have been prepared by the high energy activation method with WO3 concentration ranging from 1 to 10 molt The samples were thermal treated in a microwave oven at 600 C for 20 min and ...

In this work an off-the-shelf, modern, integrated temperature, pressure and humidity sensor was interfaced to a PIC18F4550, a popular 8-bit microcontroller. A bit-banging SPI protocol was implemented. The SPI clock was set ...

Humidity sensor is a special type of gas sensor which is sensitive only to H2O molecules. It has a large variety of applications in industrial, household and agricultural equipments. Humidity ceramic sensors have been ...

CaZrO3 stoichiometric and non-stoichiometric (CaO- and ZrO2-excess) powders were synthesized by a chemical method which is based on polymeric precursors. The mesoporous material was characterized using X-ray diffraction ...

In this work we proposed a relative humidity (RH) sensor based on a Bragg grating written in an optical fiber, associated with a coating of organo-silica hybrid material prepared by the sol-gel method. The organo-silica-based ...
