In this Automated door opener and lighting control system we use raspberry pi along with passive IR sensors, motors, and lights to demonstrate an automated door opening and lighting control system. The system allows for automated door opening using human detection with lighting control using a raspberry pi. The system detects human presence and then opens the door automatically depending on the human sensing input detected. Also, the system keeps track of lighting conditions in the room and depending on the lighting needed system switches lights to get the desired illumination. Also, the system tries to detect the number of humans present in the room and then operates the lighting accordingly. All sensor data including PIR as well as light illumination data is constantly transferred to the pi processor for processing which takes necessary actions as and when needed.

The proposed system uses ultrasonic sensors attached to raspberry pi in order to detect user hand positions. Based on the input received the user may change different beats or add effects in between. We use multiple ultrasonic sensors to allow for a variety of sound effects. Our system uses a speaker in order to play those beats.
We here use a raspberry pi board in order to get fast processing and no break constant music beats for good sound effects. Thus our proposed system puts forward an innovative beat maker and mixer system.

Project Description:
Raspberry Pi 3 B: Raspberry Pi is a Microprocessor which has 40 pins with 27 GPIO pins, it has a 1 GigaBytes of RAM and an SD card slot for the storage or the ROM,it can be used as a mini computer for low computing operations, it has a dual-band LAN, faster Ethernet, Bluetooth, it also has USB and HDMI ports for connecting devices. This device can be used as a server which we are doing in this project.
Micro SD card: You will need a minimum of 8 gigabytes SD card for this project, this SD card is used as the ROM of the raspberry pi. Use 32 Gigabyte or 64 Gigabytes of
Display: You can use any kind of display for the project, like monitors, TV or any size display that fits your requirement to configure the Pi.
Power Supply: Raspberry Pi needs a power supply of 5V and 2A Micro USB type.
Mouse and keyboard: You will need this to control, monitor, and to configure the Pi.
PIR motion sensor: PIR stands for passive infrared sensor they are also called as Pyroelectric sensor or IR motion sensor. This sensor detects the IR radiations emitted by humans and animals if a human move in the range of the sensor the radiation is absorbed by the sensor and motion can be detected. The range of the PIR sensor is 3-7 meters, it detects any IR radiation in the 3-7 meter radius. The sensor can be calibrated with the sensitivity and the delay of the IR detection.
Relay Module Use relay module to actuate the loads.
High power motors:The High power motors are used to actuate the door.
Project Implementation:
Install the Raspbian OS into the SD card, and boot the Raspberry Pi.
Install Python IDE 3 in Raspberry Pi.
Connect your Display, keypad to the raspberry pi.
Write a Python program with which you can actuate the door and the light when there is a user in front of the door.
You can use the high power motor to actuate the door.
Project Brief:The Raspberry Pi when configured and all the required software has been installed then the Pi is ready to be used as an automated door opener and automatic light control. The person if in front of the door the PIR sensor detects the IR radiations and door opens, when the door opens the light also switches on, this can be done with all the rooms in the house and the number of persons in a room can be counted using the number of PIR detections, the count is done by using two PIR sensors on outside the door and one inside the door.
Software requirements:
Raspbian OS(Debian Linux): Raspbian operating systems are based on Linux, Raspberry pi are also compatible with Windows and IOS but prefer any Linux based OS
Python IDE 3: Python IDE 3 is compiler where you can write and compile python program.
Programing Language:
Linux (terminal commands)
Python
Kit required to develop Automated door opener with lighting control:
