In processing data science, data is needed as input. Sometimes the data needed does not exist in public data, this is where the purpose of this research is made. The acquisition process is so important to process information into data. After that, the data is processed to make a decision. Micro-controller in controlling conditions, such as temperature, and humidity are very common devices, and a lot of research has been done. Sometimes discussing it only shows how to create a series and save it on online platforms, such as firebase, tinger.io, and many others online platforms. So that the process of storing data on an external or online platform is an advantage for platform providers, where platform providers do not need to do business and get data for free. This is without realizing the researchers who have produced a micro-controller device. Many platforms for storing data range from hardware and software devices. Some devices are paid or open source. This research uses software tools that are open source. Because using open source-based tools it will be easy to develop and for further research purposes. The development of the following research by entering code into a micro-controller system or what is called an embedded system. Data is a very valuable asset. Because data is one of the most important components in processing in data science. And it is better to take care of the data logger. This research uses Arduino as a micro-controller and ultrasonic distance sensor and potentiometer
Freshwater fish farming is currently booming in Indonesia, and many use small ponds for efficiency or due to limited location, this can be a problem due to Indonesia's hot climate. Small ponds with not much water volume will cause the water temperature to rise more easily on hot days, of course this is not good for the fish colonies in it. To prevent temperature rise, farmers generally irrigate ponds with fresh water to stabilize the water temperature. Due to the unpredictable weather in Indonesia lately, it will be difficult for farmers to monitor their ponds manually, so a tool is needed that can detect the heat of pond water and turn on the water pump to irrigate ponds. This research is expected to make it easier for farmers to regulate pond temperatures more easily. The use of a microcontroller in Internet of Thing devices is very much needed, considering that the microcontroller is able to carry out the task of controlling the existing sensors. The sensor used in this study uses a temperature sensor that is used to control the pool water. The prototype for detecting pool water temperature and increasing water flow is used to reduce heat in pool water and increase water flow that is reduced due to evaporation of water during the day. The purpose of this research is to make a prototype to detect pond water temperature and increase pond water discharge which is useful for reducing pond water temperature to be cooler and reducing the risk of fish death. The prototype developed is a NodeMCU ESP 8266 micro-controller, a temperature detection sensor in water, a relay as a switch and a mini pump
Currently, the development of information technology is very rapid, coupled with the development of the internet of things which is also very fast. This encourages many researchers to use information technology devices and internet of things devices to solve problems in the field. The Internet of things is a device that can communicate between one device and another. Currently, there are many internets of things devices that have been used in everything, including Smart Home, Smart Office, Smart Campus, and others. There is a problem, where currently there is a lot of theft of goods or the transfer of goods that are not known by the owner. This problem encourages researchers to conduct research, by making prototypes to be able to find out about objects that have moved. So that the owner of the goods will know, that the goods have moved without notifying the owner. This research is to detect motion sensors using MPU6050. Where the sensor has two functions, namely accelerometer, and gyroscope. Both sensors are able to find the coordinates of the x-axis, y-axis, and z-axis. The most widely used and affordable microcontroller is the Arduino Nano or Arduino Uno. The purpose of this study is to detect motion with the MPU6050 sensor, then the detection results of the x-axis, y-axis, and z-axis are sent via SMS media with the SIM900A device. The use of a prototype has many functions, it can be used to detect falling objects, detect falling motorcycles, and others. This device is equipped with a SIM900A module which functions to transmit coordinate data via Short Message Service (SMS).
Agriculture is an industrial sector that produces raw materials such as rice, corn, and agricultural products. In the current era, there should be no problem if there is a food shortage because society, industry, and education do not make a real contribution to supporting the agricultural industry. The state also needs good agricultural land, so that the state can fulfill the needs of its people. Without good agriculture, a country will not be able to meet the needs of its people. Modern society today is not or is rarely concerned with agriculture. Agriculture is carried out only by providing fertilizer, water, and land, paying attention to the quality of the agricultural land. One of the problems of declining agricultural production is crop failure. One of the reasons island for agriculture. Soil is the most important part of the world of agriculture. If the land is not cultivated then the land is difficult to become an ideal place for agriculture. The Internet of Things can be used as a solution to problems by tilling the soil and monitoring soil conditions. In conditions in the dry season, soil moisture needs to be done by water. In the rainy season, the land should not be flooded, let alone submerged and flooded. In order to maintain the balance of moisture and waterlogged soil, the Internet of Things is a solution for monitoring and managing agricultural land. Internet of Things is a device that can communicate with each other from one device to another, such as sensors and actuators. Good land cultivation makes agricultural land fertile. Agricultural land processing is maximized by adding a monitoring system for agricultural land using a micro-controller Arduino Uno, NodeMCU ESP8266, several sensors, and integrated devices. The purpose of this research is to make a prototype that is useful for monitoring agricultural land
Currently the development of information technology is very fast in its development. Up to all fields can not be separated from information technology. In the industrial era 4.0, there are also a lot of Internet of Things devices. Almost every field has used many IoT devices. The presence of IoT-based devices is very helpful in modern human life today. Moreover, with the development of microcontrollers and open source makes someone create a device quickly. One of them is making a prototype for sensing objects. By utilizing the Arduino Uno microcontroller and Ultrasonic sensors to create a sensing prototype. The results of this sensing can be displayed on notebooks and mobile phones. The microcontroller also sends sensing sensor data via Bluetooth as a wireless communication medium. Called Internet of Thing if a device can send signals to other devices. Various data communications can be via wireless or wire. Mobile app that is used to display sensing results from Ultrasonic sensors. Use of the App Inventor platform as a front end for mobile apps. This device is only limited to a short distance. Due to the limitations of the Ultrasonic sensing sensor it does not exceed 1 meter. This prototype can be developed using a longer distance and can be applied to remote sensing, if changing the sensing sensor with a remote sensing sensor.
