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: Slope monitoring systems using a wireless sensor network is an efficient technique to track slope movements or failures. Instability in slope contributes greatly in hazards caused to lives ...

Want to get started with the A121 radar sensor from Acconeer? It is a powerful but not so easy-to-master sensor. In this article, we cover background information and several tips for putting it to use ...

v6 is a ground-up rewrite from Arduino onto ESP-IDF + FreeRTOS: independent FreeRTOS tasks for radar read, motion smoothing, LED rendering, web serving, and ESP-NOW peer-mesh — no more cooperative ...

Excited to share my first review, written for CNX Software! This time, we’re diving into the Seeed Studio mmWave Human Detection Sensor Kit, which harnesses the power of mmWave radar. The technology I ...

This paper presents the first microwave-sensor-node integrated into a short-range wireless sensor network based on ZigBee technology. The node includes an analog front-end circuit, a Frequency ...

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 ...

Laboratory of Mechanics and Soils Modelisation, University Iba Der Thiam of Thies, Thiès, Senegal. Pavement auscultation generally involves a series of more or less destructive tests which, in ...

Proximity sensing is a common application for intruder alarms, light switches, and other home and industrial automation applications. There are multiple methods of proximity detection used in the ...

First, install the Analog Frequency library for measuring the frequency pulse and detecting the signal waves (this will later convert into the object speed). Then, install the U8g2 library for the ...

Motion detection is a common application for intruder alarms, light switches, and other home and industrial automation applications. And there are several ways to do it. We have already used a PIR ...
