Non-contact Water Level Monitoring System Implemented Using LabVIEW and Arduino

This paper shows non-contact water level monitoring system implemented using LabVIEW and arduino. Water depth of the tank is measured by Ultrasonic sensor. Hence the water level present in the tank is known. Depending on the sensor reading LabVIEW program sends the data to arduino and through arduino board the pump is switched ON if the water level in the upper tank is low and pump is switched OFF if the water level is completely filled in the upper tank. The input to arduino board is from ultrasonic sensor. Arduino read the height and reports the water depth of the tank and the same is displayed in LabVIEW front panel. Advantage of this over other existing automatic system is it provides non-contact water level measurement using ultrasonic sensor, but existing automatic system using ss(stainless steel) sensor which is a contact type water level sensor and also these sensors quickly corroded by some chemicals. The same is present in LabVIEW using the graphical user interface for visualization, LabVIEW communicate with add on devices like arduino, ultrasonic sensor, pump through makerhub.
