Abstract

Calibration is required for various kinds of tools from kitchen tools such as stirrers or mixers to medical tools such as temperature calibration, ECG, blood pressure, and other instrumentation tools to be according to the required standards. In medical devices, a digital tachometer has been used as a calibration support device to measure the speed of objects that rotate in RPM on the centrifuge. Some medical devices are calibrated in km/hour, for example, the ergo cycle and treadmill. Two different devices or a conversion from RPM to km/hour are required. The research aimed to design a measurement device that performed calibration of devices with different units, namely tachometer that can be used to measure speed in RPM and km/hr. Based on the research objective, a tool was made to measure the motor's rotational speed using the E18-D80NK sensor, microcontroller, and LCD without touching the object being measured.

Abstract

The goal of the research was to develop a Proportional Integral Derivative (PID) control DC motor system as a Matlab-based driver mini conveyor to discover how to regulate speed on an actual mini conveyor where certain factors that impact the research are not considered 0. The hardware configuration of the mini conveyor used hollow steel as a frame and two copies of the roller belt for the stretch belt conveyor. The PID control system used an empirical approach to get the DC motor's response system to determine the best fit of proportional gain, integral gain and derivative gain, and then implement those PID control systems using Matlab and Arduino as the tools for data acquisition. The speed sensor (Rotary Encoder) was mounted on the roller belt to accurately gain read speed. This sensor will submit data on every increasing in PWM to accurately measure the speed and control speed at the same time, based on the set points. The consequence of this work was the proportional gain values = 0.94624747, the Integral gain = 51.4023958 and the derivative gain = 0.01941504. The PID control, designed to monitor the response of motor DC speed on this research, had successfully reached set point value and decreased steady state error from 47.16 percent to 1.015188 percent (unloaded) and 2.2020751 percent (loaded) on the real response device.

Abstract

Measuring body temperature depends on the type of thermometer and measured body area. A thermometer placed on the tympanic membrane is considered ideal because the tympanic membrane and hypothalamus have arterial blood supply originating from the carotid artery (neck). Therefore, it is considered directly close to the core temperature. The Tympani Thermometer with external storage can facilitate the doctor's performance in diagnosing patients. This tool is designed using the MLX90614 sensor as a passive infrared sensor that can receive infrared energy from the tympanic membrane. The study aims to design a tympani thermometer. It compared the measurement results of the designed tool with ear thermometers that have been calibrated to get the error value. Based on the results, this prototype works well and has an error of 0.7°C in the left ear and an error of 0.24°C in the right ear.

Abstract

Baby incubator is very important to keep the newborn’s body temperature especially for premature babies. The research aimed to design a baby incubator with controlled temperature and humidity. The incubator is designed to have a length of 60 cm, a width of 40 cm, and a height of 30 cm. System of baby incubator will automatically turn on or turn off the fan and or heating in accordance with the normal range of temperature and humidity in the incubator. The normal limits of temperature used is 33°C to 35°C. While the normal limits of air humidity in the incubator used is between 40% and 60%. Data acquisition system consists of temperature and humidity sensor, microcontroller ATmega8535, fan, heater, and LCD. LCD is used to display the results of measurements of temperature and humidity. Heater is used to regulate the temperature in the incubator. While fan is used to regulate the humidity in the incubator. Test results show that the heater will turn on if the temperature is below the limits of 33°C. While the fan will turn on if the humidity is above 60%

Abstract

In everyday life, particularly in hospitals, people typically use cloth or tissue to dry our hands. It seems less practical, effective and hygienic. In addition, some restaurants still use cloth or tissue as well. To overcome this problem, several hospitals and restaurants have provided hand dryers. It can dry hands but cannot eliminate germs or bacteria. It is necessary to create a hand dryer equipped with a sterilizer. This work, therefore, created a hand dryer that can simultaneously dry and sterilize hands that worked automatically using the ATMega8 microcontroller. The tool was designed by using an infrared sensor to detect hands, and an ATMEGA8 microcontroller to read and process the sensors to activate UV and heating. The results found that the tool equipped with UV and heating can dry hands while eliminating bacteria and germs.

Abstract

An incubator room is conditioned to keep the temperature warm so the baby feels comfortable. A temperature monitor system for incubator room placed separately from where the officer works is a hassle. It wastes time. Temperature detector design for infant incubator which has constant temperature is necessary. An LM35 sensor as temperature detector was used in the design. The sensor was installed in a 100 x 80 cm room. The detected temperature was displayed on the LCD and computer in the staff room. Temperature (°C) is converted by an Arduino Uno microcontroller into an ADC (Analog Digital to Converter) value. Several LM35 sensors were mounted in rooms to detect the temperature. The LM 35 sensor was used by considering that it can be calibrated directly in the Celsius scale, a linear scale factor of 10mV/°C and has temperature range between -55 ° C and 150 ° C.

Abstract

This research will discuss health services in the role of diagnostics and life support. The system designed is a system that is able to provide information on the user's health condition, in this case, is a measure of heart rate and body temperature. In taking heart rate data using a heart rate sensor (fingertip sensor). This system works taking data from the blood flow on the index finger for the 60s, the data will be displayed through the LCD. For body temperature parameters the data collection uses the LM35 temperature sensor. Changes in sensor heat will be converted into electricity, which is translated into digital form through a 10-bit ADC that is processed by the ATMega 16 microcontroller and displayed to the LCD. The results of an ideal measurement show the error of each parameter heart rate and body temperature min 1.702% and 0.55%
