Design and Implementation of Monitoring System Automatic Water Level Reservoir Controller

Bali’s water crisis, according to a study by The Bali Institude for Economic Development and Planning (IDEP) revealed that the water crisis in Bali is expected to worsen aswater supply in Bali just only 20 percent. Bali’s water crisis cause most of the population in South Bali use a deep wells and keep the clean water in the reservoir/water tank. The application of conventional techniques in measure water level automatically was inefficient and ineffective because difficulty in monitoring. This study offers one method in measurement of water level using ultrasonic sensor (contactless sensor). Sound waves generated from ultrasonic transducers are capable of measuring water levels in real-time and continuous, sophisticated, reliable, more accurate by using microprocessors as signal processors and at low cost. Real time measurement results show the measurement accuracy level with standard deviation of 0.71756 cm at the measurement distance from 5cm up to 150 cm
