Two Parameters

One part of the geoelectric method is DC (Direct Current) resistivity measurement. Physical parameters measured by the system are the current and potential difference. From these two parameters, the resistance value is obtained based on Ohm’s law. Based on the current-potential electrodes configuration in the DC resistivity measurement, there is the possibility of contact between the potential-current electrodes and also the position of the potential electrodes that can be exchanged. Thus, an auto-range Voltmeter is needed which can measure the potential difference with the order of mV up to hundreds of volts and can measure negative potential difference value (reversed polarity). This research aims to build a Voltmeter prototype using ADS1115 (namely ADC with 16-bit resolution) and Arduino Uno, which can be applied in DC resistivity measurement. In this system, there is internal resistance and switch. The internal resistance is around 2.4 MΩ, arranged into a voltage divider circuit to be able to measure the maximum potential input around 1,600 V. The switch function is to set the measurement mode (as auto-range), which is set by Arduino Uno. Furthermore, ADS1115 uses a differential measurement method to be able to measure a negative potential difference. Based on the results of tests on several resistor components with an adjustable voltage source, the Voltmeter is good at measuring the potential difference in resistor values below 10 KΩ with a confidence level of around 97%.

           Tsamaroh Nidaa Putri, Priyo Sasmoko explains that accumulator is a combination of several pieces of cells used for altering the chemical energy into electricity energy used in motor vehicles. Accumulators are used continuously will shrink and drop so it needs to be recharged. To know the state of the battery voltage drop experienced the need for a measurement to determine the ability of the accumulator. Design manufacture accumulator discharge monitoring tool consists of a voltage divider circuit to know the big accumulator voltage in percentage form. Used also an ACS712 current sensor to detect the discharge current and LM35 temperature sensor to determine the temperature of the accumulator. The control system used is the Arduino UNO microcontroller and an LCD for displaying the measurement data. Normal voltage ranges accumulator 12,5V - 13,8V. Accumulator with a capacity of 5Ah takes 8 hours to process discharge when using 20 watt lamp load. If the voltage of the first accumulator on the LCD shows the percentage of 0 % then automatically the system will work to discharge  for a second accumulator. The duration of use depends on the large accumulator load used. Keyword:Accumulator, ACS712,  capacity accumulator, Arduino UNOReferencesAgustin, Leonandi. 2015.

The use of DC source voltage obtained from solar cells and DC generators varies in value depending on the surrounding natural conditions, for that a controller is needed which functions to regulate the voltage in carrying out the charging process to the accumulator. This paper will discuss about the design of charge controller based on Arduino Uno R3 with ATmega328 microcontroller. This controller is used to regulate the charging process from a DC source with a maximum open circuit voltage of 24 Volts, which is then used to charge the 12 Volt accumulator. This charge controller works by sending a source voltage that is regulated by pulse width modulation. When the accumulator voltage is 13.8 Volt, the controller will carry out a charging process with a duty cycle of 95%, if the accumulator voltage is> 13.8 Volts and ˂14.4 Volts, charging will be carried out with a duty cycle of 10%, and if the accumulator voltage exceeds 14.4 Volt, the charging process will be stopped. Some protection equipment is also included in this charge controller such as overvoltage protection, overcurrent and also control of the connection breaker to the load when the accumulator voltage is weak, and a disconnect from source to accumulator when the accumulator condition is full. To show the work of the whole system, with the Arduino Uno R3 microcontroller the parameters of source voltage, accumulator voltage and percentage of accumulator status are displayed on the LCD screen then 2 LED lights and a buzzer as indicators during the charging process and when the accumulator condition is weak. From the results of the voltage reading on the voltage divider sensor, it has an error of less than 6.22% at the source terminal and 6.89% at the accumulator terminal..

A 100 kv scanning transmission microscope has been built. Briefly, the design is as follows: The electron gun consists of a field emission point and a 3 cm Butler gun. The beam has a crossover outside the gun and is collimated by a condenser lens.The parallel beam passes through a defining aperture and is focused by the objective lens onto the specimen. The elastic electrons are detected by two annular detectors, each subtending a different angle, and the unscattered and inelastic electrons are collected by a third detector. The spectrometer that will separate the inelastic and unscattered electrons has not yet been built.The lens current supplies are stable to within one part per million per hour and have been described elsewhere.The high voltage is also stable to 1 ppm/hr.
