===Use-cases for sensors===
•	
RFID – Security system/Access control
 
•	Humidity & Temperature, Gas Sensors – Air quality / temperature control. Regulate air flow with fan and motorized windows/doors.

•	Passive infrared sensor (PIR) – Motion sensing. Measure occupancy and automate certain tasks e.g. turning on/off fans, lights, other sensors.

•	LCD – Display important information/status of the IoT system, or any other messages.

•	RGB LED – Provide status information on, e.g. energy consumption, active modes, critical statuses and other information about the system

•	Yellow LED – Simulate indoor/outdoor lamp

•	Steam Sensor – Detect weather changes / water leakage etc. Use to automate motorized doors/windows

•	Wi-Fi/Bluetooth – Connect microcontroller to the internet for better processing power or web/mobile application integration for monitoring and data analysis

•	Buttons – For executing actions such as changing modes or unlocking doors.
