Rancang Bangun Alat Ukur Ketinggian Air pada Wadah Berbasis Arduino Uno Menggunakan Bazzer dan Sensor Ultrasonik HC-SR04

Abstract

Water is an important requirement in human living, availability of water should always be well fixed in households, offices, public facilities or industries. This led to the role of water storage to be important to ensure the availability of water every time Mechanisms measuring water levels are automatically required to keep availability of this water. One of them is by making the water level sensors are fed back to the water pump filling the water tank. Variable resistor that is the type trimer potentiometer (trimpot) multiturn can be used as a sensor element which changes the height of the water will turn a knob or trimer variable resistor. This will produce a voltage change which is the analog input to the ADC 8 bit 0804 type. Digital output of the ADC will be entered into the port of AT89S52 microcontroller is further processed to appear as the water levels and conditions of the water pump on a 16 x 2 LCD display type M1632. The circuit is also equipped with a water pump life and death of the microcontroller is set to die if the pump tank is almost full and alive again when tank is almost empty. The results of equipment testing demonstrates that this equipment has been able to show the height of water in a storage tank of LCD displays with the same actual situation as been shown in the bar.
