Arduino has certainly made its mark in the world of DIY electronics, providing an accessible platform for a wide range of creative and interactive projects. Known for its user-friendly hardware and ...

Hello, today I am going to review the HUSKYLENS 2, released in October 2025. It is the next generation of HUSKYLENS, an AI vision sensor equipped with a Kendryte K230 dual-core RISC-V SoC with a 6 ...

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 ...

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 ...

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 ...

Abstract: Floods are one of the annual natural disasters experienced by Malaysia and the rest of the world. Destruction of infrastructure, economic losses, and casualties are among the adverse effects ...

1. Union Pacific 2-6-0 Mogul No. 40 refills its tender from the water tank in Poulsbo on Greg Privette’s HO Olympic Logging layout. A computer-triggered servo under the water tank operates the spout ...

This article exhibits the sizing, modelling, and characterization of a power supply (output 3.3 V, 200 mA max, 11 days full autonomy) dedicated to powering a wireless sensor node without a battery but ...

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 ...
