Abstract: A flying vehicle, or guided missile that gets a boost or a rapid reaction to the propellant material from the engine output is called a rocket. The Indonesian Army really needs measuring tools to determine the ability of a rocket to be made. Therefore, in this study the author will design a temperature measuring device, thrust, and temperature on a rocket with a rocket load of 1 ton. The research method used is pure experiment. This study aims to find data on temperature, thrust, and temperature on the rocket in order to find out the specifications needed so that the rocket can fly as desired. The resulting data will later be sent to the raspberry pi to be processed in order to get the results which will later be printed on paper that will be used for a research on making rockets to help the Indonesian Army in developing defense equipment in the rocket field.

On The Road

Measuring friction between the tyres of a vehicle and the road, often and on as many locations on the road network as possible, can be a valuable tool for ensuring traffic safety. Rather than by using specialised equipment for sequential measurements, this can be achieved by using several low-cost measuring devices on vehicles that travel on the road network as part of their daily assignments. The presented work proves the hypothesis that a low cost measuring device can be built and can provide measurement results comparable to those obtained from expensive specialised measuring devices. As a proof of concept, two copies of a prototype device, based on the Raspberry Pi single-board computer, have been developed, built and tested. They use accelerometers to measure vehicle braking deceleration and include a global positioning receiver for obtaining the geolocation of each test. They run custom-developed data acquisition software on the Linux operating system and provide automatic measurement data transfer to a server. The operation is controlled by an intuitive user interface consisting of two illuminated physical pushbuttons. The results show that for braking tests and friction coefficient measurements the developed prototypes compare favourably to a widely used professional vehicle performance computer.

Temperature Measurement System

For automatic temperature measuring and logging purposes in solar thermal experiments, a single board computer - Raspberry Pi based and sensor system is proposed. Different data sets are observed for sensors, thermometers, and thermocouples and they are compared. The consistency of the automated temperature measurement system is also verified.

Information Recovery

In this paper, we designed a device to measure a heartbeat using fingertip and we also designed to measure the body temperature. Notwithstanding, the issues that happen in wellbeing administrations is that clinical staff need quite a while to look at patients, patient information recovery is still traditional, and gear utilized as yet utilizing the link media. To tackle the issue, this proposes a pulse observing framework and internal heat level utilizing Raspberry Pi. This examination intends to calm the weight of clinical work force in observing the patient, shorten the time in taking patient data and diminish the occasion of misdiagnosis.
