Design And Manufacture

This research discusses the design and manufacture of a voltage sag detection device using a data logger system. Voltage sag detection device to detect the presence of voltage sag which is one of the power quality problems in industrial electrical systems. Voltage sag can cause disturbances in electronic components that are sensitive to changes in voltage values. In this device, the voltage sag is detected using a voltage sensor by reading the RMS voltage from the PLN 220V AC source, then it is converted into a digital signal. The digital signal is sent to the ESP32 module to be processed and outputs a voltage value which is then displayed on the LCD Display. The voltage value data collection is carried out every <10ms and the data taken is the voltage value <90% of the rms voltage. The data taken is then saved to a micro SD card and displayed on the LCD Display. Several tests were carried out to ensure the performance of the voltage sag detector as designed. By switching the 110 / 220VAC transformer connected to the voltage sensor for 10 seconds, 12 seconds and 17 seconds. Based on these tests, the voltage sag detector can read and store the voltage sag data when the voltage read is below 90% of the rms voltage.

When transporting the goods from one place to another place the components should work perfectly according to our application. This project shows you how to get temperature and humidity values for particular components which are kept in a certain room or area or during the shifting process along with the real time clock. Sometimes due to room temperatures also we can observe a change in the component readings. So in that cases, data logger systems will be helpful. Here we are measuring various weather parameters like temperature, humidity, time and date. For this we require sensors for getting temperature and humidity values and a real time clock is used to get real time. We can retain previous values also by using previous records. Finally, we can display these parameters on the LCD display and save the records so that we can access the previous records. For this storage we can use controller memory or else externally we can connect the memory called SD-card.

The data collector to calculate the efficiency of the pure sine inverter DC to AC based on the level of efficiency, voltage and current stored automatically in Micro SD has been successfully designed. This data collector is built from the Arduino Nano (ATmega328) module as the controller and uses a Micro SD Card as a storage medium. The equipment storage results are displayed in real time using the RTC and LCD as a display medium for the measurement results of the voltage sensor and current sensor. The data logger is designed to be useful for storing data from the measurement results of the DC to AC inverter which consists of voltage, current and data collection time. The data every 16 seconds will be stored automatically on the Micro SD. The results of the reading error of the voltage sensor and current sensor are 1.088% and 1.72%, respectively. The results of the error reading the voltage sensor and current sensor are still precise, so the efficiency obtained in this study is 78.37%.

Piezoelectric Solid-State Micro-machined Modal Gyroscope is a new kind of gyroscope sensor based on MEMS. According to the characteristics of the gyroscope signal, the after-treatment processing system is designed and implemented, including A/D convertor by AD7656 and data storage by SD card. After applying Kalman filter to the digital signal on DSP, 71.8% decrease of standard variance of initial signal is achieved remarkably, which lays the foundation for the practical application of piezoelectric micro-machined modal gyroscope.
