Echo433 (formerly 433MHz-Cloner) provides a streamlined way to intercept, log, and replay 433MHz radio frequency signals. Whether you are auditing home automation systems, testing RF remotes, or ...
Abstract: This paper presents a wireless communication system utilizing a 433MHz RF module alongside human presence detection using a Passive Infrared (PIR) sensor. The system is designed to enable ...
Abstract: In this study, we present the design, fabrication, and measurements of a 3-D heterogeneous integrated RF-module at W-band. A 3-D transition structure based on micro-bumps is fabricated and ...
The HC-12 has a great range for 433MHz but the downside is that the module can only communicate with another HC-12. Also the price for these modules are very similar to ESP8266 and LoRa devices at ...
