Abstract

This project represents the water tank depth sensor system design for measurement of water level using Arduino and LabVIEW software. Ultrasonic sensor is used to measure the water depth, and from that measurement it calculates how full the tank is. Depending on the sensor reading LabVIEW program sends the data to Arduino and switches ON the pump when the water level in the tank goes low and switches it OFF as soon as the water level reaches a predetermined level. The ultrasonic sensor connected to the Arduino board as a input signal. The Arduino then reads the height of the water and reports the depth of the tank. The same program is interfaced with LabVIEW and in the front panel of LabVIEW and can visually see the level of water tank and how the motor is ON and OFF depend on the water level requirement.
