This project demonstrates motion detection using Arduino Uno and different ESP NodeMCU modules. The system consists of two NodeMCU devices—one acting as the client and the other as the server. The ...

Initially, I was planning on using bluetooth as the communication to the controller device, but the range would be only about 10 meters, so I decided to opt for a Wi-Fi connection instead to have a ...

This system is implemented using the NodeMCU ESP8266 Wi-Fi module, Arduino Uno, 4 channel relay module, temperature sensor (DHT 11), LDR and PIR sensor. The system can control home appliances both of ...
