Water Tank Depth Sensor Arduino

Water tank depth sensor arduino. Theoretically when the sensor is not in the water the measured value at the sensor pin is approx 1 0855 v which would be equivalent to 1347 bits. In this project we will use an ethernet shield to have the arduino connect to an online datalogging service called pachube to generate graphs of water depth over time but you could also have it make decisions on the basis of the reading to control items such as a water pump or irrigation system solenoid.

In this project we will use a wishield that provides wifi network connectivity to report the current water level using a web interface. The ping sensor measures distance using sonar. When water has been pumped into the tank up to the point that thesensor measures a distance of 14cm the red led comes on again as water keeps filling up the tank and gets to the point the sensor measures 8cm the blue led comes on finally when water gets close to the brim of the tank where the sensor measures a distance 3cm the white led. The arduino then reads the output of the transducer and reports the depth of the tank.
An ultrasonic well above human hearing pulse is transmitted from the unit and distance to target is determined by measuring the time required for the echo return. The arduino then reads the output of the transducer and reports the depth of the tank. This arduino water level indicator uses an ultrasonic sensor or ping sensor to determine the level of water in the tank.
