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 ...
Abstract: This article proposes a low cost of USD 72.5 BoM with a small size of water level monitoring IoT sensor without Ultra-Sonic level sensors. The power consumption for sensing and RF ...
Abstract: This paper presents a novel liquid level monitoring system based on passive ultra-high frequency (UHF ... Compared to the state-of-the-art, the system reduces measurement errors by 4.39%, ...
Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water. Researchers have developed a new optical ...
