Design Tool Room Temperature Measurement with Temperature Sensor Using Lm35 At89s51 Microcontroller

In writing that I make with the title "Room Temperature Measuring EquipmentDesign With LM35 Temperature Sensor Using AT89S51 MICROCONTROLLER "about design for temperature data acquisition system that uses the basic componentsof an ADC, temperature sensor, microcontroller AT89S51 and Seven Segment as aviewer facility. Temperature data acquisition system into something that is veryimportant in industrial activity, because it is a small part of a process control. Withregard to the importance of the system, hence the temperature data acquisition systemdesign that is capable of temperature monitoring activity of a plant. The data to bemeasured is a physical property so as to be processed temparature and displayed inthe form of electrical systems used LM35 temperature sensor that is able to convertthese quantities with increasing 10mV/oC.To be able to design the system was first carried out the process of cha nging thetemperature into an analog voltage using a LM35 temperature sensor. after goingthrough the process was strengthened by the signal conditioning, analog voltageconverted into digital data using the ADC 0804. Digital data obtained is thenprocessed by the Microcontroller AT89S51 and displayed, so we get someinformation about OC units of the plant temperature on a Seven Segment of thetemperature data acquisition system design is obtained that this system has the abilityto measure the temperature from 25oC to 100oC with average errors Averagetemperatures for the appointment of 0.266 oC

Development of an electronically-scanned pressure module for operation at cryogenic temperatures

Pressure and temperature characteristics were measured for a number of multichannel electronically scanned pressure sensors. The tests were made on commercially available units designed to operate in a controlled temperature environment. Measurements of zero shift, sensitivity, and nonlinearity for each transducer were taken over a temperature range from 100 K to 340 K using a computer controlled data acquisition system. The units tested failed to meet accuracy specifications over the complete temperature range, which was expected. However, the sensors showed acceptable and predictable behavior over the temperature range from approximately -40 C (233 K) to 70 C (343 K). It was determined that a combination of local heating and accurate temperature monitoring can result in a device that can be compensated for temperature as well as its other physical properties. The design of a prototype for operation in a cryogenic environment is proposed, and a method for compensation is developed

Who Should I Approach? Knowledge Sourcing in Enterprise System Implementation

During enterprise system implementation, organizations transfer system-related knowledge to end users through training sessions and by having them involved in the system design and implementation processes. However, during actual use of the system, end users acquire informal knowledge from co-workers through their social networks. Existing research has focused on the structural features of social networks and their impact on regulating knowledge flow between end users and across the network. The personal attributes and preferences of end users that could impact their knowledge acquisition and processing capabilities have not been considered. This paper examines the expertise level of end users, their gender, and the complexity of their job tasks in influencing system-related knowledge acquisition and its impact on performance outcomes. Data for this study was collected from active users of a new Enterprise Resource Planning (ERP) system that had been implemented across multiple business units of diversified business conglomerate in the United States

Access to medicines in Brazil based on monetary and non-monetary acquisition data obtained from the 2008/2009 Household Budget Survey

Objective: to investigate the access to medicines by Brazilian families by monetary and non-monetary acquisition data. Methods: this is a cross-sectional study based on data obtained from the 2008/2009 Brazilian Household Budget Survey. The units of assessment were households that participated in the survey and the data on the acquisition of medicines over the 30 days prior to the interviews. The medicines were classified according to the Anatomical Therapeutic Chemical classification system. Results: acquisition of medicines was reported by 82.9% of Brazilian households, with 2.38 medicines/household, and 0.72 medicine/individual. In the South and Southeast regions, the average acquisition was slightly greater than the national average (2.53 and 2.49, respectively). In 22.3% of Brazilian households, it was reported that a medicine was not acquired due to lack of financial resources, mainly in the North and Northeastern regions, and in rural areas. Approximately 15.0% of medicines were obtained with no costs, 90.1% of them by the Brazilian Unified Health System. The medicines most acquired were those acting on the nervous system (28.8% of Brazilian households), on the cardiovascular system (15.7%), on the digestive tract and metabolism (14.3%), and on the respiratory system (12.1%). Overall, the quantity of medicines acquired was greater in higher socioeconomic classes of the population, with the exception of antiparasitic products, most likely because of the precarious sanitary conditions faced by less privileged social classes. Conclusions: the acquisition of medicines is a common practice in Brazil, being reported by over 80.0% of the Brazilian households in 2008/2009. Although the data obtained from the Brazilian Household Budget Survey have some limitations, the information obtained in this study can help health authorities to design national and regional policies to guarantee access to these products while promoting their rational use

Towards a reliable approach on scaling in data acquisition

Data acquisition is an important process in the functioning of any control system. Usually, the acquired signal is analogic, representing a continuous physical measure, and it should be processed in a digital system based on an analog to digital converter (ADC) and a microcontroller. The ADC provides the converted value in ADC units, but the system and its operator need the value expressed in physical units. In this paper we propose a novel design solution for the scaling module, which is a key component of a digital measurement system. The scaling module refers to fitting the sensor result of a variable number of bits depending on the ADC resolution into physical units. A general method for scaling is proposed and a SageMath script is presented for obtaining easily the scaling function. In the last part of the paper, the proposed method is validated in a case study, by calculus, and it is implemented on a low-cost development system in order to create a wireless sensor node.Comment: Paper accepted for ICSTCC 2019 - 23rd International Conference on System Theory, Control and Computing, October 9-11, 2019, Sinaia, Romani
