Abstract: This article presents a portable optical fiber sensor (OFS) design for continuous liquid level measurement, fabricated using two pieces of bare polymer optical fibers (POFs). The proposed ...

In this article, we will learn how to similar speed sensor using Arduino and IR sensor. By setting up the two IR sensors at a fixed distance from each other, we can track the time it takes for the ...

The initial plan was just to have water level sensors reporting data over a modified CATS packet radio transmitter. On the other end, the plan was to capture the feed via a CATS receiver ...

Moree Plains Shire Council notified residents that its water treatment plant in the town has experienced a pump failure. As a result, to preserve supply, significant Level 5 water restrictions ...

The kit includes 18 essential items, featuring an ADIY Uno DIP R3 (CH340C) board compatible with Arduino, along with a range of sensors such as IR, sound, gas, soil moisture, and more. It also ...

which relies heavily on borewells for water, with an estimated daily extraction of 800 million liters. In central Bengaluru, the groundwater level is predicted to decline by 5 meters, while areas ...

The UNO is one of the most popular boards in Arduino family and a great choice for beginners. Ultrasonic Sensor: These are the sensor that use ultrasonic waves to detect objects or to measure the ...

Since an HV system draws power from water and is partially immersed in it, it is much safer than batteries that can explode during a fire. Additionally, conventional fire sensor systems are prone ...

Hydrovoltaic (HV) mechanisms, in which electricity is generated by the direct interaction of nanostructured materials and water molecules, have recently emerged as promising, cost-efficient ...

Watmonitor is a universal web interface designed to efficiently store water level data collected from sensor nodes into a centralized database. It empowers users to monitor real-time water level and ...

Thus, the aim of this study was to analyze the reliability of using a differential pressure system to measure in-water force during front crawl in young competitive swimmers. It was hypothesized that ...
