Porte à Puce is a smart door security system with passcode, temperature, and humidity sensors built using an Arduino microcontroller. It has a keypad to enter a passcode, displays humidity and temperature readings, and will open automatically if the temperature reaches 35°C. It was created as a student project and cost approximately 443,000 Indonesian Rupiah to build using components like an Arduino, LCD screen, sensors, motors and other electronics. The system provides basic home security and safety functions while keeping costs low.

13. Description
Porte à Puce is derived from the french words /Porte/ meaning /door/ and /puce/
meaning /chip = the incredibly complex yet tiny modules that store computer memory or provide
logic circuitry for microprocessors/.
So, Porte à Puce defined as the smart door with various useful fuction in simple circuit display.
The following spesification of Porte à Puce :
1. Security door with passcode and buzzer security alarm (To open the door password required,
if the password is wrong, buzzer will on )
2. Monitoring RH and Tdb (RH and Tdb value will display on LCD 16 x 2)
3. Control Tdb (when the value Tdb reach the setpoint the door will open automaticaly to
exhaust heat from the room)

22. Servo Motors
Servo motors have three wires: power, ground, and
signal. The power wire is typically red, and should be
connected to the 5V pin on the Arduino board. The
ground wire is typically black or brown and should be
connected to a ground pin on the Arduino board. The
signal pin is typically yellow, orange or white and
should be connected to a digital pin on the Arduino
board. Note that servos draw considerable power, so if
you need to drive more than one or two, you'll
probably need to power them from a separate supply
(i.e. not the +5V pin on your Arduino). Be sure to
connect the grounds of the Arduino and external
power supply together.

24. Hex Keypad 4x4
Hex key pad is simply an arrangement 0f 16 push button
switches in a 4X4 matrix form. Typically a hex keypad will
have keys for number 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 and letters A,
B, C, D, *, #. The hex keypad will have 8 connection wires
namely R1, R2, R3, R4 and C1, C2, C3, C4 representing the
rows and columns respectively. The schematic diagram and
photo of a typical hex keypad is shown in the figure.
The program identifies the pressed key by a method called
column scanning. In this method a particular row is kept low
and other rows are held high. The the logic status of each
column line is scanned. If a particular column is found low,
then that means the key that comes in between that
column and row is short(pressed). Then the program
registers that key being pressed. Then the same procedure
is applied for the subsequent rows and the entire process is
repeated. For example if row 1 is kept low and column 1 is
found low during scanning, then that means key”1″ is
pressed.

25. Buzzer or Piezoelectric speaker for
arduino
A Piezoelectric speaker or buzzer is a loudspeaker that
uses the piezoelectric effect for generating sound. The
initial mechanical motion is created by applying a voltage
to a piezoelectric material, and this motion is typically
converted into audible sound using diaphragms and
resonators.
Piezos have polarity, commercial devices are usually
having a red and a black wires indicating how to plug it to
the board. We connect the black one to ground and the
red one to the output. Sometimes it is possible to acquire
Piezo elements without a plastic housing, then they will
just look like a metallic disc.

26. LED
A light-emitting diode (LED) is a two-lead
semiconductor light source. It is a p–n
junction diode, which emits light when
activated. When a suitable voltage is
applied to the leads, electrons are able to
recombine with electron holes within the
device, releasing energy in the form of
photons. This effect is called
electroluminescence, and the color of the
light (corresponding to the energy of the
photon) is determined by the energy band
gap of the semiconductor.

porte à puce

37. Modification
We include the function of the door not only as the automatic safety door from a burglar, but
porte à puce is also the safety door from fire and extreme temperature by using :
The buzzer as the alarm if someone enter the wrong passcode, and also if fire or extreme
temperature occurs
The DHT Sensors that could identify the relative humidity and temperature
We controll the door to open (servo to rotates for about 90 degrees) if the room temperature
reach 35ºC

39. Conclution
We live in an age where the crime rate is high, while technology has changed rapidly, the thief
become a genius thief. So we must to be a genius too, increasing the level of security and safety
is necessary, no more for manual, it’s time for automation.
Our Porte a Puce is right choice to increase our security system with low cost and worthed
features.

40. Hope for the future
May this project could be useful for improvement of safety and security efforts in
this automation era. We hope someday we could upgrade Porte a Puce with
another features, by :
◦ Adding the fingerprint sensor, so only authorized people can access Porte a Puce for entry
◦ Adding the fire sensors, gas sensor, Liquefied Petroleum Gas (LPG) sensor, and smoke sensor
to improve the safety functions. So, when the sensor detects the presence of fire, LPG, toxic
& flamable gases and smoke, the buzzer will ring and the door will automatically open to
rescue people inside.
◦ Implanting the chip inside Porte a Puce, to simplify the circuit display
