💧 An IoT-based Smart Water Meter system for real-time monitoring of water quality (pH, TDS) and flow rate using ESP32 and Arduino UNO. It includes automatic motor control, cloud logging via ...

Abstract: Access to clean drinking water is critical for public health, yet many water sources contain dissolved solids, salts, and microbial contaminants that are not visually detectable but pose ...

For setups that rely on stored water, clear awareness of tank level and water quality is essential. Traditional level monitors are often bulky offline devices with only simple LED indicators, while ...

Abstract: TDS automatic data collection was designed based on a sensor and Arduino board using red laser beam communication. The sensor was calibrated by measuring 4 different water solutions using a ...

Recent advancements in radio frequency (RF) sensing technology can be attributed to the development of the Internet of Things (IoT), healthcare, RF-identification, and communication applications. RF ...

Total Dissolved Solids (TDS) is a measurement for detecting the potability of water. Both humans and aquatic creatures require a suitable level of water content to survive. TDS value > 1000 ppm ...

Active enrollment in rehabilitation training yields better treatment outcomes. This paper introduces an exoskeleton-assisted hand rehabilitation system. It is the first attempt to combine fingertip ...

What is Turbidity in Water and Why Measure It? Turbidity is the degree or level of cloudiness or haziness of a liquid. This happens due to the presence of large numbers of invisible particles (which ...
