DESIGN AN INTERNET OF THINGS-BASED BLOOD PRESSURE DETECTOR AND MONITOR

A sphygmomanometer is a tool for measuring blood pressure that is often used in the medical world. Sphygmomanometers are generally divided into 2, namely analog and digital sphygmomanometers. In modern times now Android smartphones have developed with various features that are already very sophisticated. Therefore, the author wants to design a digital sphygmomanometer that can measure blood pressure and provide a history of measurement results so that the public or patients candetermine the state of their blood pressure. To present this tool in  this study, the  author will try to integrate a digital blood pressure measuring instrument with IOT (internet of things) so that it becomes a  blood pressure detection and monitoring tool. NodeMCU ESP8266 will be used to process data and also serve to connect to the internet. Then, the sensor used is the MPX5050GP sensor as a pressure measurement tool and then the pressure calculation data from the sensor is sent to Firebase which acts as a database, and later it can be accessed and monitored via a smartphone. Theresults of testing the sphygmomanometer tool that the researcher made and the testing of the comparative sphygmomanometer tool. On average, this test gets an accuracy difference of approximately 1%

Automatic Coffee Maker Machine Based on Internet of Things (IoT)

In this era of globalization, technological developments are very rapid penetrated in all fields in particular. in the food and beverage sector..During a pandemic like this, as entrepreneurs, food and drink must adapt. Adaptation in question is hygiene in the process of making drinks and food. One example. it is an automatic drink making machine. that can help in the process. make drinks more practical and hygienic to keep more sterile. when making drinks in terms of blending drink ingredients. the process of stirring and pouring hot water. In an automatic drink making machine, in a supermarket there are still many weaknesses. ie the user is still making physical contact, such as approaching and selecting the menu and waiting for the process to complete. Based on the problems that exist among the general public, an idea was formed to design and manufacture an Internet of Things (IOT) based automatic drinking machine. which can help users in terms of making a drink. Users only need to select the drink menu that they want to make on the Android smartphone application that is connected to the access point, then the machine will carry out the process of making drinks. according to the menu selected in the application. The user only takes drinks to the places that are available. Based on the results of testing and analysis carried out on a machine this helps users to place orders and can enjoy drinks that are processed automatically

Wire-Mesh 16 × 16 Capacitance Sensor for Analysis of Capacitance Distribution on Cylindrical Pipe

The wire-mesh sensor is an intrusive sensor device that uses for generating 2-dimensional (2D) images of fluid flow. Sensors made of 2 layers copper wires, transmitter, and receiver, that perpendicular each other. The wire-mesh sensor will directly to measure the value of inductance or capacitance at the crossing wire. There are 208 data measurements in 16 × 16 cylindrical wire-mesh sensors. All data measurement then processed by Python software to obtain a 2D image of the capacitance distribution. Experiment results show the inhomogeneous distribution of capacitance that occurs in the wire-mesh sensor. Three types of liquids, distilled water, tap water and salt solution, showed circular pattern of capacitance distribution, with the highest capacitance value being in the central area of the image, while at edge area has a lower capacitance value than the central are

ARDUINO UNO BASED AUTOMATIC DESIGN TO BUILD WINE DRINKING TOOL USING SOIL MOISTURE SENSOR

The development in this era is increasing, humans expect a tool or technology that can help human work, because now technology has become a human need. Therefore, a device that can do watering the wine is made automatically. This tool aims to replace manual work to be automatic. The benefits that can be obtained from this tool is that it can facilitate human work in watering grapes. This tool uses a soil moisture sensor which functions as a soil moisture detector and sends commands to Arduino uno to turn on the relay driver so that the pump can flush water according to soil needs automatically. The making of this final project is done by designing, creating and implementing system components including Arduino uno as a controller, relay drivers for turning on and off the water pump, LCD (Liquid Cristal Display) to display soil moisture values. The results of the research prove that the tool made can function properly and can be developed as expected. The tool can water the vine when the soil humidity is below 50%, and turn off the pump when the soil moisture is above 50%

Arduino Based Temperature And Humidity Monitoring Control System for Day Old Chicken (DOC) Cage

In general, conventional cattle sheds using manual systems and human labor are very reliable, in the conventional process of heating cattle sheds, we still encounter many using oil stoves and lamps as a DOC heating process. However, the use of oil stoves and lamps is dangerous and unstable. In addition to the DOC heater using the lamp, there is also a DOC heater using an element heater.             The advantage of using a heating element, the temperature can be adjusted according to your needs. The use of heating elements in chicken coops is still rarely used. Therefore, a research was conducted on the manufacture of a temperature and humidity monitoring control system based on Arduino Mega in the Day Old Chicken (doc) cage.             DHT 11 sensor accuracy level calibrated with room temperature measuring instrument Taffware HTC-2 is known DHT 11 sensor has an accuracy in reading temperature that is 96% with a dispute of 3.8%. And the accuracy in reading humidity is 89.8% with a difference of 11%

ANALYSIS OF OXYGEN CONCENTRATION VALUES IN PORTABLE OXYGEN CONCENTRATOR DEVICES BY USING SILICA GEL AS FILTRATION MATERIAL

Oxygen concentrators as a means of separating pure oxygen from free air became an item that was quite sought after when the pandemic case hit in the past 2020 to 2021. This device works by taking free air around us and then processing it by passing the air through a filter so that oxygen is separated from other gases, most of which are nitrogen. However, not all oxygen generator devices are able to filter oxygen to the maximum, this depends on the filtration material used. Most portable oxygen generator devices use synthetic zeolite as a filtration material, but have not maximally filtered oxygen, therefore in this study researchers examined the effect of using silica gel when used as an oxygen filtration medium in the same oxygen concentrator device. In the results of this study, it was found that there was an increase in the oxygen concentration from the standard media device using synthetic zeolite compared to using silica gel material, the increase in oxygen concentration that occurred increased by around 3.3%

CONTROL SYSTEM FOR TEMPERATURE, HUMIDITY AND TIME PARAMETERS ON ZELIO SMART RELAY-BASED WATERING PROCEDURES

Watering plants usually done manually using human power. that has risk negligence and inaccuracy. also, in time and cost is not efficient. Another factor that can affect the quality of crops is a factor of humidity and temperature. For those reason, writers made a tool that can work according to the level of humidity and temperature automatically and continuously. This tool uses Zelio Smart Relay as automatic controller. The 808H5V5 humidity sensor and LM35 temperature sensor is used as input. The LM35 temperature sensor detect the ambient temperature, where as 808H5V5 humidity sensor detect ambient air humidity, and time of watering adapted to the Smart Relay timer. The entire sensor input is programmed using ZELIO SOFT 2. Setting the temperature and humidity when the detected 30oC and >70% as well as the timeshows at 08.30 – 09.00 am and 16.00 – 16.30 pm the pump will automatically ON
