New technology introduced new multiple ways to control home appliances and light, one of these technologies is Capacitive touch which has great advantage over normal mechanical ways like long life time, and better UI.
This project introduce a system to control Home light (ON/OFF and Brightness), the main way to control the light is using Capacitive touch. With touch buttons the user can Turn ON/OFF light, and with touch Slider the user can adjust the brightness level.
The system can also Set the light ON if there is person presence in the room was detected using the mic sensor. Also the system will set the light ON if it detects an authorized person using RFID technology.
The System consists of two parts (Nodes), the first node is the master node which is used to control the light (ON/OFF or Brightness) based on input from CapSense. Also it will detect person presence in the room using the Microphone and will trun ON the light accordingly. Also will receives notification from the Security node if there is an authorized person.
The second Node is the security access node which is used to interface with the RFID module, to read the Access cards and check if the read card is in the allowed list. Once the Security node detects a valid card it will send to the Master node to turn ON light.
The SW was built in a layered architecture with abstraction between different layer to make it easy to update the SW or changing some parts of the HW without the need to rewrite the full SW.
The Current SW was tested using the LED instead of An AC Lamp, so the next step is add the AC wiring along with AC lamp,
