Accurate monitoring of reservoir water levels in urban and agricultural environments is essential but is often performed visually, a method that is both time-consuming and labor-intensive. This study ...

The ultrasonic beam from this sensor penetrates the skin, detects signals reflected from the vessel walls, and measures changes in vessel diameter. Using this principle, it measures the real-time ...

I built a mini radar system using Arduino UNO, HC-SR04 Ultrasonic Sensor, and SG90 Servo Motor, paired with a JavaScript-based visualization dashboard 🖥️. The servo sweeps from 0° to 180°, collecting ...

I’ve just come across a no-name non-contact, high-precision 80 GHz mmWave radar sensor for liquid level detection with a 40m range, ±5mm accuracy, and Modbus communication over UART. The 0.15m to 40m ...

Abstract: This paper deals with parking space detection by using ultrasonic sensor. Using the multiple echo function, the accuracy of edge detection was increased. After inspecting effect on the ...

RPS-429AA-40P-IS2 intrinsically safe (IS), ultrasonic sensor achieves precise accuracy in distance measurement and object detection applications. With ATEX, IECEx and C-UL-US certifications, this ...

Recently I came across some non-contact liquid level sensors and gathered them out of curiosity. They have been available in the market for the past few years, but this time I was lucky enough to get ...

Process Sensing Technologies (PST) has recently launched a range of intrinsically safe optical liquid level switches. Using innovative infrared technology and the principle of total internal ...
