In this project, we build a long-range appliance control system using two Arduino Nano boards and Reyax RYLR999 LoRa modules. In this project, we build a long-range appliance control system using two ...

Compared to the Arduino Uno of old, modern microcontrollers are absolutely tiny — especially for the amount of processing power and I/O you get. But if you need something really small, like ...

"Where did my pet go?" If you have a pet, you've probably asked this question at least once. One moment they're playing ...

Abstract: Recent years have witnessed rapid deployments of low-cost, low-power devices in living environment to support various Internet of Things (IoT) based monitoring systems and sensing ...

Abstract: Physical-layer security (PLS) schemes use the randomness of the channel parameters, namely, channel state information (CSI) and received signal strength indicator (RSSI) to generate the ...

There are two ways to deal with improving ham radio receivers, or — for that matter — any sort of receiver. You can filter and modify the radio frequency including the radio’s intermediate frequency, ...
