![]() ![]() The voltage of the direct current source must first be converted to 0 -5V voltage level before going to pin Analog to Digital Converter using signal conditioning circuit consisting of a buffer circuit, a voltage divider circuit, and a Differential Amplifier circuit. Voltage drop detection system tool here using microcontroller ATMega 8 as a whole system controllers, regulators direct current power source as a means of testing, 2x16 LCD to display the measured voltage value and status alerts, LED as an indicator of stress conditions, as well as a warning buzzer sounds in the event of supply voltage that is not normal. The principle works the tool works based voltage condition is detected on the status of the drop, normal and over. Therefore, to anticipate the need for a warning system to anticipate the supply voltage unstable. Unstable voltage supply can cause damage to electronic equipment on the system. One example, the Airbridge Huawei BTS 3606, power supply subsystem and the main part is very important to the performance of the entire device. ![]() Each telecommunication technology would require the power supply as the supply voltage. The development of today's telecommunications world is built based on technical standards and definitions developed from the telecommunications world, and set a guideline that each piece of equipment is plugged in between one another. ![]()
