How to check the liquid level in a given tank? Of course, with a special liquid level sensor! The measurement of the liquid level in the tank is useful in many individual and industrial applications. One does not need to look far for examples. We have a fuel level indicators in cars, at home we can have a septic tank level sensors, an indicator that measures the specific amount of water in an aquarium or in the swimming pool. Such liquid level sensors are extremely popular, the more so as many of them are easy to integrate with other programmable electronics components. The products presented here can be used independently and integrated with Arduino or Raspberry Pi modules. Thanks to this, these devices can be freely used in your own projects, building various home automation projects, Internet of Things projects and others.

Electronic sensors for measuring liquid levels and soil moisture
Electronic measurement of water-related values always generates some risk - conductive liquids can cause short circuits in the device and corrode its metal elements. The situation is no different in the case of liquid level sensors - if they come into contact with e.g. water, they must be properly protected against its influence. Of course, remember to protect not only the level sensor itself, but also the Arduino module, if we place it, for example, in a tank with water.
Non-contact sensors for measuring liquid levels
Not all liquid level sensors are equally susceptible to damage caused by contact with, for example, water. Our store offers a wide range of non-contact liquid level indicators in the tank . These devices may use different mechanisms of operation. Some of them use photoelectric methods, others are based on capacitive measurements. Many of these types of sensors are compatible with e.g. Arduino modules and other development platforms, which facilitates their use in prototype devices. This type of sensors are ideal for measuring the level of aggressive liquids and for conducting measurements in high-pressure tanks .
Floats for threshold level measurement
Level sensors using floats - either mechanically integrated with the sensor or magnetic floats with a reed switch in the liquid level indicator in the tank are a perfect solution for systems where information about the exact level of liquid in the tank is not important and only information about reaching a certain predefined level is sufficient. . This type of level sensors will be useful, for example, in a system monitoring the level of rainwater in a garden tank - such a system can inform you that the tank is full. If we add, for example, an Arduino module and a solenoid valve, the tank can empty automatically so that it never overflows.
Dedicated sensors for testing soil moisture
Sensors dedicated to testing soil moisture allow for electronic measurement of this parameter, e.g. in a lawn. This type of level sensors will work well in the garden or on the balcony. If you have an irrigation system in your garden, you can fully automate watering with the help of this type of liquid sensors and a module such as Arduino. When Arduino detects lower soil moisture than set, it will send information to the pumps in the irrigation system, which will ensure that water reaches the plants.
Liquid level sensors - FAQ
Liquid level sensors are used to measure the liquid level in the tank. You can find them in cars (fuel level indicator), but at home they can be used as an indicator of the level of a septic tank, the amount of water in an aquarium or a swimming pool. They work great with platforms for electronics and programmers, e.g. Arduino .
The type of material from which the sensor housing is made should be selected depending on the medium being measured. Consider how liquid media will pool and cover surfaces. You may need a dedicated non-contact sensor. Also pay attention to chemical compatibility.
