Abstract

Accumulator dump is one of the tools used to convert serial data into parallel data on RFID communications. Accumulator dump on RFID communication consists of a series of counters and registers, where one of the supporting circuits in the counter and register is D flip-flop. D flip-flops are one type of flip-flop that is built using RS flip-flops. Discrete circuit design Master-slave flip-flops  are  built  using  NAND  logic  gates  built  using  0.35  µ m  CMOS technology. The results of the D flip-flop circuit design are simulated using LT- SPICE software to see the speed of response and power dissipation in the circuit. Keywords: RFID, CMOS 0.35 µ m, D flip-flop, Dump Accumulator, NAND logic

Abstract

RFID tags are divided into active RFID tags and passive RFID tags. In this case  using  a  passive  RFID  tag  that  is  supported  by  using  a  13.56  MHz frequency radio signal. RFID technology is used here to monitor nutrients in the nursery process in the planting medium. The method used in sending data via the 13.56 MHz radio frequency is the Accumulator Dump method. Accumulator dump is a method to change the output of Delta Sigma ADC in the form of serial data into parallel data. The accumulator dump is built from a series  of  registers  and  counters.  For  the  counter  circuit  itself  uses  a combination of NAND gate circuits, Flip-Flop D circuits and Half Adder (HA) circuits. For the half adder circuit itself, it consists of an EX-OR gate and an AND gate. By using 0.35u technology, this half adder circuit is designed on LT- Spice tools which require an input voltage of 3.3 Volts with 11 PMOS and 11 NMOS, with a value of W = 1u and L = 0.35u to produce the desired output. The frequency of the half adder circuit is 50Hz with a maximum power consumption of 0.00363Watt. Keywords: Tag RFID Pasif, Dump Accumulator, Counter, Half Adder

Abstract

Efforts can be made to overcome this natural disaster, including providing a drainage system, maintaining forests and monitoring river water levels to determine the possibility of flooding if the level exceeds normal. In this research the author designed a tool to provide warnings before a flood disaster occurs. The design of an automatic water level monitoring system using an ultrasonic sensor (HC-SR04) based on Arduino UNO with a computer interface based on Microsoft Visual Basic 6.0 was created using HC-SR04 to measure distance, Arduino UNO as the main controller for the entire tool, LED and buzzer. When the HC-SR04 measures the distance by emitting waves from the trigger pin as the trigger and the echo pin as the receiver, the distance will then be processed by the Arduino UNO to calculate how many "cm" distances have been measured. If the distance calculated by the Arduino UNO is < 30 cm then the green LED will light up, if the distance is < 20 cm then the yellow LED will light up and the buzzer will sound slowly. However, if the distance is <10 cm, the red LED and yellow LED will light up alternately and the buzzer will sound loudly. Next, the data will be displayed on the PC interface with Microsoft Visual Basic 6.0 according to the distance received.
