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 ...
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 ...
