“…After testing, the data retrieval would be performed to compare the data obtained from the tool with the data not used by the tool. The block diagram in Figure 1 illustrates that the system consists of a Load Cell Sensor to weigh water mass and has a maximum weighing capacity of 1 kg, a DS18B20 [25]- [27] sensor that is a waterproof temperature sensor that can be used in the temperature between -55 o C to 125 o C, an Arduino [28]- [30] Uno R3 as a circuit controller for the system using the ATMega 328 [31], [32] microcontroller, and a 16x2 LCD to display the measurement results.…”

A measure of liquid thickness is needed to make a dough or formula for medicinal syrup. The tools to measure the thickness available in the market are analog that is less accurate and precision. To overcome these problems, digital density measuring devices are needed. The limitation of the digital density meter, especially liquid, urges the author to carry out further research on the digitization of this measuring instrument. This research aims to make a digital density meter for liquid matter with a high level of measurement accuracy, as the reference measurement study for liquid density in digital form. The instrument was designed using the load cell method as the main sensor. It was also equipped with a DS18B20 waterresistant temperature sensor to measure the temperature of the liquid. The data were analyzed to obtain the accuracy and error of the liquid density measurement from the density meter. The liquid samples used for research were Pertamax, solar, and water. Sample accuracy and error measurement results were 99.83 percent and 0.17 percent respectively for Pertamax, 99.63 percent and 0.37 percent for solar and 99.46 percent and 0.54 percent for water. The measured density value was finally shown on the 16x2 LCD.

“…Indeed, several innovative solutions have been developed to assure vaccine storage and distribution under specified limits. For instance, the authors in [18], have surveyed different data loggers, and proposed a basic model of temperature data logger system, whereas, the authors in [19], have designed a temperature & humidity data logger based on cypress CY8C29566 microcontroller. Furthermore, the authors in [20] have proposed a data logger system based on atmel atmega32 microcontroller which allows to use any microcontroller with and without USB host/USB OTG for accessing USB drive.…”

“…However, the aforementioned methods have certain limitations which restrict them to become an effective solution for COVID-19 virus vaccine, storage, and temperature monitoring. For instance, the hardware of [19] is limited to 4000 logs and microcontroller have high current consumption in sleep and standby modes, whereas in [20] no hardware is realized and based on atmega32 which have high current consumption. Moreover, [21] is based on LM35 temperature which has high response time and arduino uno board which can effect the sensed data (since the generic board doesn't have temperature specific components).…”

With the outbreak of the Covid-19 pandemic, vaccination has become mandatory. Further, for effective results, the vaccines should be stored within the recommended temperature range, typically between 2 • C to 8 • C, transported safely without any mishandling and temperature excursion. In order to assure vaccine potency, it is essential to have detailed information on the entire temperature data recorded at user-defined intervals. In this paper, we develop functionality interaction to bring different sensors, memory, and processing units to an integrated platform, providing a compact, power-efficient, and low-cost commercial Tem-peratuRE, Humidity, and MOvement Data-logger (THERMOD). Moreover, the THERMOD hardware is packed with interactive algorithms that address the aforementioned concerns and log the real-time temperature and jerks (3-dimensional movement) encountered throughout the journey, and the logged data can be retrieved by plugging THERMOD into the host computer/laptop. The THERMOD hardware formulation and algorithm embedding have been done in the institution lab, which enables end-to-end storage and monitoring. Also, the proposed design is built with the defined standards by health organizations, e.g., WHO. Further, to validate the proficiency of the proposed design, comparative analysis has been done; a) a cost analysis has been done to state the cost efficiency of the proposed solution, b) real-time power performance graphs have been plotted which depict that THERMOD outperforms the existing solutions. Moreover, a number of experiments were performed for the validation of the proposed design.

Submarine gliders are specialized systems used in applications such as environmental monitoring of marine fauna, in the oil industry, among others. The glider launch and capture is a costly process that requires substantial technological and human resources, so the orderly and error-free storage of data is of fundamental importance due to the subsequent analysis. The amount of information being obtained from the seabed is increasing, this leads to the need to develop robust and low-cost ad-hocsystems for this type of application. The challenge is the integration of the different software layers in the storage system because the monitored variables must be ordered according to different glider operations such as calibration data update and navigation. Additionally, to avoid data corruption in the memory chip, error control coding must be used. The goal of this paper is to present a novel design of different layers of software integrated into a datalogger: reception, error control, and storage logic for the different glider operations. The design of the datalogger is based on a NAND flash memory chip and an MSP430 microcontroller. To correct bit-flipping errors, a BCH code that corrects 4 errors for every 255 bits is implemented into the microcontroller. The design and evaluation are performed for different glider operations, and for different lengths and correction capabilities of the BCH module. A test to calculate the storage time has been carried out. This test shows that in the case of 256 bytes per sample, at 30 samples per minute, and 1 GB of storage capacity, it is possible to collect data from the glider sensors for 84 days. The results obtained show that our device is a useful option for storing underwater sensor data due to its real-time storage, power consumption, small size, easy integration, and its reliability, where the bit error rate BER is of 2.4 ×10−11.
