Abstract

This paper discusses about design and development of gimbal smartphone, which are made to be simple and less money consuming by utilizing microcontroller and MPU 6050 sensor. Recently, the development of videography and image processing is inseparable from the rapid advance in smartphone technology. One of the most popular features is camera. Hand movements and shocks cause fewer maximum results. To improve the quality of camera captures and video, it is necessary to have a stabilizer for camera position.  Thus, it is expected that the outcomes of this paper are able to give contribution for cheap gimbal smartphone. Design and implementation of gimbal uses acrylic as the material, with 5 mm of thickness. This MPU 6050 sensor is optimized to detect sway in axis X, Y, and Z or roll, pitch, and yaw. Gyroscope and accelerometer provide input to the microcontroller, which will process for output on 3 servomotors that function to maintain the camera’s position at a specified set point. The results show that MPU 6050 sensor can response angle reading error of 1.34° of roll, 0.25° of pitch, and 0.78° of yaw. Error in maximum servomotor movement is 1.5°. Thus, it can be concluded that gimbal can work optimally with less money consuming as well as low error. It is expected that the next research will add other suitable and accurate control, that is, PID or fuzzy.

Abstract

Monitoring and controlling the use of electricalenergy can help in controlling the excess use of energy. Infacilitating monitoring and controlling, a smart electricalterminal application system has been designed with a WEBdisplay that is used to control electrical equipment thatintegrated into the local network. The controlled condition isthe ON/OFF from the relay that connected to the electricalterminal. This system can also monitor the state of theelectrical terminal through reading the current when there is aload attached to the electrical terminal. The Arduino webserver is used as an ON/OFF electrical terminal, and theArduino web client for current readings. Both Arduino isconnected to access point, so control and monitoring can bedone wirelessly. Monitoring of electric current uses an ACS7125A sensor, which can detect changes in current up to 5 A.Every single electrical terminal is connected to one sensor, so inthe system, it uses four ACS712 sensors. Based on the results ofthe tests, the four ACS712 sensors have been produced indifferent reading values. The difference occurs because of thedifference in response time from the four sensors, with anaverage reading between 0,04 A to 0,07 A on a no-load test.Data obtained from the results of reading electric current sentto the database, the average reading displayed in the WEB

Abstract

Employee performance can be measured by their presence or attendance, which applies to both civil servants and non-civil servants. Because the attendance system still uses the manual technique, it is considered inefficient due to the potential for data fraud and attendance problems. In addition, the government is adopting precautions against viruses in office buildings to maintain business continuity while the pandemic is being addressed. This study aimed to employ a facial recognition system and temperature measurement to lower the danger of COVID 19 transmission while minimizing paper use by using a facial recognition system as a substitute for presence. It has so far permitted the digitization of formerly manual sights. The OpenCV library allows computers to detect faces using the haar cascade classifier approach and Python as a programming language. A Logitech C930e webcam with a resolution of 1080p at 30fps was used to capture facial data, which was then processed on a Raspberry Pi 4 microprocessor. It uses an MLX90614 sensor to monitor body temperature, which is controlled by an Arduino Uno microcontroller. It is well integrated into the database based on body temperature testing and facial recognition. The development of a more accurate temperature sensor reading method for distance and employee body temperature is a priority for future research.

Abstract

The educational environment is the process of educational activities, so the environment is expected to be comfortable and avoid noise. Noise can be disturbing, such as the ringing of mobile phones or sounds produced by humans. Sound noise in a room can cause loss of concentration, so that indoor activities can be disrupted. Based on these problems, it is necessary to have a tool used to detect the noise level of sound in the classroom. Therefore, a noise detection system in the learning room uses a sound sensor based on NodeMCU ESP8266, which can send email notifications and be monitored through the thinger.io application. The location of this research is in a classroom. This tool consists of hardware (hardware) including NodeMCU ESP8266, PIR Sensor, LCD 16x2 I2C, Sound Sensor, DF Player Mini Mp3, Speaker, and Android application software. The working principle is that if the decibel value exceeds the predetermined value, the room user will hear a warning sound and send an informational text in the form of an email notification. Based on tests on several parameters, testing using the sound of a drilling machine obtained an error value of 8.7%. In music sounds, an error value of 7.7%, and inhuman screaming sounds, an error value of 8.1%. The tool has been successful in the test results and can be implemented in the classroom.
