Produced heat from motorcycle exhaust has been used to recharge cellphone batteries using a thermoelectric seebeck generator and program settings from the Arduino microcontroller. This tool consists of an LM 35 sensor that functions as a temperature reader, TEG as a heat converter to voltage, DC to DC Booster as a voltage controller, Arduino Uno as a data processor, LCD as a display. The software in this tool uses the Arduino IDE program. This tool is used to convert heat into voltage. The working principle of this system in general is that when the exhaust heat is removed, the controller will read the data from the LM 35 temperature sensor. After that the data will be processed by the microcontroller. After obtaining the processed data, the result data is then displayed on the LCD and the relay circuit will activate the system when the required voltage is appropriate

The Impact

<em>Flood disasters still occur regularly and continuously in Indonesia. Flooding can occur due to the volume of water in the river beyond the river body. Many impacts caused by flooding, not only material losses, flooding can also cause loss of life. The impact of flooding can be reduced if people are better prepared to face the flood. One way is to quickly disseminate information on river water levels to the community. It is necessary to make a solution on how to design an automatic sluice using Arduino UNO R3 and how to monitor the water situation during floods. The working principle of this tool uses an ultrasonic sensor as a water level detector, Arduino as a data processor, servo motor as opening and closing the door bar automatically and the modem as an SMS notification. Because design based detection system is needed In this study there are two formulations of the problem (i) How to design flood altitude detection devices using Arduino uno r3 which can open and close automatically. (ii) How to test the flood altitude detection system using a wavecome modem. The research objective is divided into two parts (i) Creating a series of flood elevation devices using Arduino r3 so that it can open and close automatically (ii) Gets the results of flood elevation system testing with an sms gateway</em>

Early Fire Detection

Lately, there are frequent fires caused by human factors. Because we cannot predict the process of fire in advance. And the delay in knowing the occurrence of a fire is very fatal to the safety of human life and property. With advances in technology, we can overcome fires by making early fire detection devices. With the presence of temperature and smoke detectors, we can detect fires as early as possible and be delivered quickly via alarms and SMS gateways. The main component of this fire detector is the Arduino Uno. This Arduino uno acts as the brain of the fire detection device. This tool works based on the detection of the temperature condition by the DHT11 temperature sensor, which is when the temperature is above normal, an alert notification will be sent via the SMS gateway and so will the MQ2 smoke and the buzzer will sound as a warning alarm.

Fuel Level

Fuel shortage is a common problem in Indonesia. This prompted many cases of vehicle fuel theft. As a solution to this problem, an Arduino-based vehicle fuel theft detector system is implemented. Arduino-based vehicle fuel theft detector system is a prototype that uses Arduino UNO as a microcontroller, IComSat v1.1 SIM900 GSM/GPRS Shield to communicate with mobile phone, fuel level sensor as a volume detector, and push button as a detector to check whether the fuel tank’s lid is open or closed. The working principle of this system is to detect the state of the fuel tank lid. When the lid is open, the system will make a phone call. Then, the system will keep track of fuel volume. If there is a drastic decrease in volume, the system will send information about the decreasing volume in the form of a short message to the owner of the vehicle. The success rate of the communication system between Arduino UNO and other electronic devices is 100%. Accuracy of fuel level sensor is 90%. Success rate of push button switch in detecting the state of fuel tank’s lid is 100%. Success rate of GSM Shield communication is 90%.

Banyaknya kasus kecelakaan lalu lintas yang terjadi di indonesia semakin meningkat dari tahun ke tahun. Salah satu faktor yang menyebabkan kecelakaan lalu lintas yaitu pengemudi yang mengendarai mobil pada kondisi mabuk. Terlebih lagi cara yang digunakan pihak kepolisisan dalam mengecek seseorang dalam keadaan mabuk atau tidak sangat tidak efektif yaitu dengan cara pengambilan sampel urine dan darah dari pengemudi tersebut. Tujuan penelitian ini adalah membuat alcohol detector yang mendeteksi kadar alkohol pada nafas pengemudi. Alat ini menggunakan sensor MQ-3 sebagai input, mikrokontroler arduino uno sebagai pengolah data, LCD karakter 2x16 sebagai penampil, RGB LED dan speaker sebagai indikator. Alat dirancang mendeteksi alkohol jika lebih dari 5%, maka kelistrikan mobil akan terputus secara otomatis. Metode yang digunakan pada penelitian ini adalah metode eksperimen.

Insight Into

In this paper, we propose a highly sensitive temperature sensor based on two cascaded Mach–Zehnder interferometers (MZIs) that work using the Vernier effect. The all-fiber MZIs were assembled by splicing a segment of capillary hollow-core fiber (CHCF) between two sections of multimode fibers (MMFs). This cascaded configuration exhibits a temperature sensitivity of 1.964 nm/°C in a range from 10 to 70 °C, which is ~67.03 times higher than the sensitivity of the single MZI. Moreover, this device exhibits a high-temperature resolution of 0.0153 °C. A numerical analysis was carried out to estimate the devices’ temperature sensitivity and calculate the magnification of the sensitivity produced by the Vernier effect. The numerical results have an excellent agreement with the experimental results and provide a better insight into the working principle of the MZI devices. The sensor’s performance, small size, and easy fabrication make us believe that it is an attractive candidate for temperature measurement in biological applications.
