Abstract: The water level indicator project utilizes an Arduino Uno microcontroller, an LCD display, and a Bluetooth module to provide an efficient solution for monitoring water levels and controlling ...

Sustainable analytical methods are highly demanded in the modern society. Within the green principles, novel procedures that attend the sustainable development goals have been proposed and the ...

Water storage often presents challenges such as monitoring tank levels, preventing overflow, and reducing manual intervention to operate the pump. Two types of devices, known as water level indicators ...

The working principle of the water level sensor module is very similar to that of a Rain Sensor. The water level sensor has three pins, runs on 5V power, and gives out the data in analog format. The ...

If you want to know the acidity (or alkalinity) level of your pool or aquarium water, you need a pH meter. In this article, you'll find a simple but effective solution based on off-the-shelf ...

The non-contact liquid level sensor uses the sensing capacitance of water to detect the presence of liquid approaching the sensor. The sensor has a specific static capacitance due to the distributed ...

Increased soil respiration due to warmer temperatures may exacerbate global climate change (Rustad et al., 2000; Davidson and Janssens, 2006; Bond-Lamberty et al., 2018), as soils currently have an ...

The “maker” movement is receiving a lot of attention, especially in the field of education. In this context, we have created an Arduino–carbon dioxide fountain, devised to use digital tools, such as ...
