This project represents the water tank depth sensor system design for measurement of water level using arudino and LabVIEW software. Here we used a ultrasonic sensor to measure the water depth, and from that measurement it calculates how full the tank is. This sensor 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 which we can visually see the level of water tank and how the motor is ON and OFF depend on the water level requirement.
