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 ...

An open source tornado path detection tool for first responders, built on NOAA NEXRAD Doppler radar data. Tornado Tracer is being developed to ingest real-time and historical Level II radar scans, ...

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 ...

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 ...

Drivers with a lead foot more often than not have Waze open on their phone so they can see if other drivers have spotted cops up ahead. But avoiding a speeding ticket used to involve a lot more ...
