In this work, we propose the development of monitoring system for the Air Handling Unit of a particular building of the University via Zigbee network. The proposed system will provide all the essential information required for the thermal modeling of the building using Dynamic Thermal Simulation. Furthermore, this will allow us to accomplish autonomous building management and also to study the thermal...
Most chemoresistive gas sensors are supported by an insulating substrate, not integrable into silicon IC platforms, and need very high temperature to reach operating performance, this implies energy consumption and a risk factor in the presence of flammable gases. Therefore, porous silicon substrates represent a good choice, thanks to its chemical and physical properties. In this work we designed...
Measuring systems in industrial environments often require a more types of sensors to refine the quality of environment. Distributed measurement system SenSys is designed to measure 1-wire sensors, but the current offer of sensors despite their undeniable advantages is too narrow. Due to the cost optimization of the necessary cabling of other types of sensors, it is appropriate to use or extend the...
The fuzzy control technology is applied in the field of temperature and humidity control, which can realize the intelligent control of temperature and humidity. A temperature and humidity fuzzy controller is designed based on CAN bus. So that temperature and humidity can be real-time monitoring and controlled. The principles method and the hardware circuit of this fuzzy control are described. Simulation...
This paper describes the design of a test system for dead-end proton exchange membrane fuel cells (PEMFC). As the requirement, an electronic load with quick dynamic response and wide adjustable range is designed, which provides various loads for the test system. A monitor for hydrogen pressure, air mass flow, temperature and humidity inside is used to maintain the stability of PEMFC. The test system...
This paper mainly presents zinc-air battery on-line detection system. The research of the on-line detection system was based on zinc-air battery production line. Using arm embedded microprocessor as the detection system core. Using sensors detect material, humidity and temperature, roller pressure in the production process, design the hardware and software platform of this detection system, and achieve...
Thick film resistance and capacitance elements have recently come to be used in miniaturized and lightweight electronic instruments. The thick-film magnetic semiconductor (IMS), with a thickness of 80 ??m, is a sintered substance based on ferrite powder and a ruthenium compound. The TMS has both the ferromagnetic and the semiconducting properties of the ferrite and the ruthenium compound. The TMS...
