In this category, we present the highest quality liquid level sensors. In addition to classic sensors, our store's offer includes soil moisture sensors that allow you to monitor the irrigation status of the lawn and potted flowers. The water level sensor will be a great solution for many electronic projects. Find out it for yourself now!

Contact-free sensors for measuring liquid levels

When choosing a sensor to measure the liquid level, you should pay attention to several important parameters. First of all, it is worth noting that not all liquid level sensors are equally exposed to damage caused by contact with, for example, water. For this reason, in this category of the Botland store you will find a lot of non-contact sensors for measuring the level of liquids in tanks. The devices work similarly, but it all depends on the specific measurement technology that has been implemented in a given sensor. Some detectors use photoelectric measurement methods. Other devices are based on capacitive measurements. Many of these sensors are compatible with Arduino, Raspberry Pi and other development platforms. All this makes using sensors for your own projects extremely easy. Liquid measurement sensors are ideal for measuring the level of aggressive liquids as well as for measuring in tanks under high pressure.

Electronic sensors for measuring liquid level and soil moisture

The electronic measurement of water related values ​​always creates a certain risk. Theoretically conductive liquids can easily cause a short circuit in the device. Additionally, metal devices are susceptible to corrosion. It is no different in the case of liquid level sensors. However, by choosing the best quality liquid level detectors you can avoid the above risks (of course, follow the manufacturer's instructions anyway).

In this category you will find not only the best sensors for measuring the level of water and other liquids, but also electric sensors for measuring soil moisture. Sensors for measuring soil moisture allow for electronic measurement of soil conditions - e.g. in the lawn. These types of sensors can be placed both in the garden or on the balcony. If you have an irrigation system in your garden, with the help of this type of liquid, soil moisture and module such as Arduino you can fully automate watering. When the Arduino detectors detect a lower level of soil moisture than previously determined, information will be automatically sent to other components (e.g. water pumps). This, in turn, will start the watering process. In practice, if you already have a little knowledge of how programmable electronics works, making such a system yourself will not be that difficult as you can think it might be!

Practice floats for liquid level measurements

Floats, or level sensors using floats, are mechanical devices that are integrated with the liquid level sensors in the tank. They are often equipped with reed switches and are perfect wherever it is important to ensure an adequate level of liquid. These types of level sensors are increasingly being used in rainwater monitoring systems in a garden tank. This type of system can indicate that the tank is full. In addition, you can still expand the project with programmable Arduino or Raspberry Pi electronics as well as solenoids. Thanks to this, it is possible to create an automatic system thanks to which the liquid container will be automatically emptied so that it never becomes full.
