Abstract: Multiple water quality sensors are required to construct a network for continuous and precise monitoring of water quality in natural environments. Therefore, low-cost sensors are necessary ...
An Arduino library for the Hi-Link HLK-LD2450 24Ghz FMCW radar sensor. This sensor is a Frequency Modulated Continuous Wave radar, which makes it good for presence detection and has some interesting ...
Abstract: In this article, a novel approach is proposed to address sensors’ significant challenges by introducing a portable planar microstrip sensor based on a dual-bandpass filter (BPF). This sensor ...
