Last year, Semtech released the LR2021 LoRa Plus transceiver chip, designed to address the low data-rate issue associated with LoRa, but surprisingly, ...
Nxbeam is a technology company specializing in the design and development of advanced microwave electronic systems and components. The company focuses on high-performance, reliability-driven solutions ...
Abstract: This paper introduces the design and implementation of an RF-based system for detecting non-cooperating unmanned aerial vehicles (UAVs). The system comprises an RF module, an automated Pan ...
Abstract: In this brief, we propose an RF module that integrates a Doherty power amplifier (PA), a low noise amplifier (LNA), and a transceiver (TRX) switch. This configuration enables transmitter (TX ...
This project uses an WEMOS D1 Mini ESP8266 module and an Arduino sketch to connect to a NTP (Network Time Protocol) server to automatically retrieve and display the local time on a inexpensive analog ...
Arduino test code is run to see if the sensors are working properly, with built-in LED flashing when the sensor is triggered, and turning off when the sensor is released. The testing of the keys ...
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 ...
