When transporting the goods from one place to another place the components should work perfectly according to our application. This project shows you how to get temperature and humidity values for particular components which are kept in a certain room or area or during the shifting process along with the real time clock. Sometimes due to room temperatures also we can observe a change in the component readings. So in that cases, data logger systems will be helpful. Here we are measuring various weather parameters like temperature, humidity, time and date. For this we require sensors for getting temperature and humidity values and a real time clock is used to get real time. We can retain previous values also by using previous records. Finally, we can display these parameters on the LCD display and save the records so that we can access the previous records. For this storage we can use controller memory or else externally we can connect the memory called SD-card.

Abstract In operating a photovoltaic system, it is required to employ hardware and software systems to monitor the parameter of the results of the solar panel conversion. Usually, monitoring the photovoltaic system is done by manual gauges and recording the measured results manually which would require a human hand. The present research designed and developed a real-time monitoring system for an off-grid photovoltaic system that could monitor the photovoltaic system performance automatically. The monitoring system design has 2 (two) subsystems. The first subsystem is a hardware system in the form of an electronic data logger system equipped with an SD card. This allowed data to be recorded on an SD card. The second sub-system is a software design developed using Microsoft in Visual Basic. The hardware and software were connected to monitor the photovoltaic results and recorded the obtained data in an SD card for further analysis.

ABSTRACT This study presents an investigation of the inner tire surface strain measurement by using piezoelectric polymer transducers adhered on the inner liner of the tire, acting as strain sensors in both conventional and dual-chamber tires. The piezoelectric elements generate electrical charges when strain is applied. The inner liner tire strain can be found from the generated charge. A wireless data logger was employed to measure and transmit the measured signals from the piezoelectric elements to a PC to store and display the readout signals in real time. The strain data can be used as a monitoring system to recognize tire-loading conditions (e.g., traction, braking, and cornering) in smart tire technology. Finite element simulations, using ABAQUS, were employed to estimate tire deformation patterns in both conventional and dual-chamber tires for pure rolling and steady-state cornering conditions for different inflation pressures to simulate on-road and off-road riding tire performances and to compare with the experimental results obtained from both the piezoelectric transducers and tire test rig.

The North

Italy is the leading producer of rice in Europe with over half of total production, almost totally concentrated in a large traditional paddy rice area between the Lombardy and Piedmont regions, in the north-western part of the country. In this area irrigation of rice has been traditionally carried out by flooding. The introduction of new combined irrigation and agronomic management practices (dry seeding followed by field flooding and in a full aerobic cultivation with intermittent irrigations), aiming to reduce the water consumption, can determine considerable effect on the landscape and the water cycle. With the aim to study in depth the water fluxes during the whole crop season, three experimental plots at the Ente Nazionale Risi-Rice Research Centre’s Experimental Station of Castello d’Agogna (PV) were instrumented. In each plot the following instruments have been installed: 1) a long throated flume and a double shaped (V-notch and rectangular) thin plate for superficial inputs and outputs, 3) a set of piezometers for groundwater levels, 4) one stage level gauge in each submerged field, 5) four tensiometers and moisture sensors clusters, 6) one eddy covariance station for vapour fluxes estimation. Most of the instruments were equipped with electrical sensors connected by cables to a wireless data logger that, in turn, send the data to a PC placed within ENR offices and web-connected by a LAN. In this way, besides the automatic download of data, it was possible to remotely control the devices, to quickly fix troubles, and to better plan the field trips. The management of the whole framework was done by a specifically developed software. In this paper the whole system, which presents some degree of innovation, is described in detail.

Pengaturan temperatur (atau besaran fisis lain) banyak dijumpai di lapangan sebagai pengondisi supaya system bekerja pada parameter ukur yang telah ditetapkan. Pengaturan besaran fisis bisa dilakukan dengan mendapatkan nilai dari parameter ukur dengan menggunakan sensor dan diolah sehingga hasil yang diperoleh tersebut dapat dipergunakan untuk mengontrol besaran yang diinginkan melalui aktuator. Pada artikel ini dibuat suatu sistem yang berfungsi sebagai data logger dan pengontrol temperatur pada pemanas air (heater) secara otomatis dengan menggunakan mikrokontroler dan LabVIEW sebagai pengolah dan penyajian datanya. Besaran fisis temperatur diperoleh dengan menggunakan sensor LM35. Kemudian LabVIEW dan mikrokontroler akan berkomunikasi untuk pengambilan data sehingga data temperatur tersebut bisa ditampilkan dalam bentuk grafik secara real time. Data ini kemudian diproses oleh LabVIEW untuk dibandingkan dengan nilai temperatur yang dikehendaki sehingga LabVIEW akan mengontrol pemanas melalui sebuah relay sebagai aktuatornya. Relay akan ON pada saat temperatur berada di bawah batas bawah temperatur yang diset sebelumnya dan akan OFF apabila temperatur lebih tinggi daripada batas atas temperatur yang telah diset sebelumnya. Sehingga temperatur pemanas akan stabil pada temperatur yang dikehendaki.

Abstract Context: Telemetric core-temperature monitoring is becoming more widely used as a noninvasive means of monitoring core temperature during athletic events. Objective: To determine the effects of sensor ingestion timing on serial measures of core temperature during continuous exercise. Design: Crossover study. Setting: Outdoor dirt track at an average ambient temperature of 4.4°C ± 4.1°C and relative humidity of 74.1% ± 11.0%. Patients or Other Participants: Seven healthy, active participants (3 men, 4 women; age  =  27.0 ± 7.5 years, height  =  172.9 ± 6.8 cm, body mass  =  67.5 ± 6.1 kg, percentage body fat  =  12.7% ± 6.9%, peak oxygen uptake [V˙o2peak]  =  54.4 ± 6.9 mL•kg−1•min−1) completed the study. Intervention(s): Participants completed a 45-minute exercise trial at approximately 70% V˙o2peak. They consumed core-temperature sensors at 24 hours (P1) and 40 minutes (P2) before exercise. Main Outcome Measure(s): Core temperature was recorded continuously (1-minute intervals) using a wireless data logger worn by the participants. All data were analyzed using a 2-way repeated-measures analysis of variance (trial × time), Pearson product moment correlation, and Bland-Altman plot. Results: Fifteen comparisons were made between P1 and P2. The main effect of time indicated an increase in core temperature compared with the initial temperature. However, we did not find a main effect for trial or a trial × time interaction, indicating no differences in core temperature between the sensors (P1  =  38.3°C ± 0.2°C, P2  =  38.3°C ± 0.4°C). Conclusions: We found no differences in the temperature recordings between the 2 sensors. These results suggest that assumed sensor location (upper or lower gastrointestinal tract) does not appreciably alter the transmission of reliable and repeatable measures of core temperature during continuous running in the cold.
