Description
Summary:Sensor characteristic is essential, especially in the instrumentation system's design and application to get accurate and precise measurements. One f the sensor characteristics is static characteristic. Several static characteristics such as linearity, sensitivity, accuracy, and precision are important to be identified.. This study assesses those four static characteristics on ultrasonic sensor HC-SR 04. The experiment method to get linearity and sensitivity of the sensor is by measuring the output voltage of ultrasonic sensor when it is placed in different distance from object. While the accuracy and precision of the sensor was analyzed from the read distance on the Arduino UNO display comparing to the distance measured by ruler. The results are then used to design an instrumentation system that was applied in water level control based on Arduino Uno. The results showed that the sensitivity of the ultrasonic sensor HC-SR 04 was 13.7 mV/cm and the linearity was 89.49% for the distance range between 0 and 100 cm. Moreover, the sensor accuracy and precision are 98.66% and 98.38%
