Water Level Sensor

The basic function of the water level sensor lies in its ability to detect the slightest change in the height of the water level in a body of water. This is possible because it involves a very simple mechanism. The working of this type of sensor is quite simple too.

The basic series of exposed conductive parallel conductors, works as a semi-permanent variable resistor (as a potentiometer), whose resistance changes with respect to the varying water levels. The change in resistivity corresponds directly to the height of water at the point where the sensor contacts the top of water. There is a small difference of around 40 ohms between the electrical potential and water's resistance value. So, even though a water sensor may be able to detect a change of water levels by sensing the voltage applied to a specific input and the change in potential, the change of water level detected by the sensors will not be very high compared to the difference between the voltage applied to it and the initial water level that it senses. The variation of water level detected by such a sensor is much less than the total water level variation that it can detect.

Water sensors are used in many areas of industry and marine life research. They are widely used for the purpose of maintaining a constant water supply for people and animals living on land or under water. They are also used in many different types of industries. Some common applications of this type of sensor are in a marine fish pond, a pond in an aquarium, and in a water tank.

These types of sensors do have one major limitation that they cannot detect very low water levels. The reason behind this limitation is that they need to maintain a constant water level in order to work. This means that even if the level of water in the pond rises significantly, the sensors will not be able to detect it unless they are moved to higher water levels and the sensors are then able to detect the level of water in the tank. This may require them to be moved back down into lower water levels again. If the sensors are moving, they can detect the increase in water in the pond and can thus alert the user to a problem.

The other main limitation of this type of sensor is that they cannot detect very high water levels. It is important to note that water sensors can detect water levels that rise as high as 40 feet above normal levels, but because of their very low sensitivity they are unable to detect levels that are below that. This limitation makes them a poor choice when used for monitoring bodies of water in remote locations.

In order to overcome these limitations, more advanced models are available which are able to monitor water levels at very high altitudes. However, even the more sophisticated water level sensors are still relatively cheap and easy to use.
