Annotation:
The article is devoted to the system of control and management in the enterprise. The article deals with burglar alarms or an alarm system.
Keywords: security system, Arduino, Raspberry Pi, threats, warning methods
The essence of the system: an employee of an enterprise or an alleged intruder, passing to a controlled territory, provides its RFID tag. The system module responsible for obtaining information from the RFID tag should read and analyze the obtained data using a database of the system containing the correspondences between the records on the labels and the employees to whom the labels belong. If the provided label is registered in the database, then the system must skip the employee[1]. Otherwise - optionally signaling the failure of authorization.
The control unit is the Arduino board with the program recorded in its controller. Reading the information from the RFID tag will take a special scheme RFID-RC522, and signals about the operation of the model of the system will be fed using a light-emitting diode and an elementary audio device (buzzer). The work of the access control module will be performed by the SG90 servo, see Figure 1.
In this case, we define "our own" with only uid. These are four bytes, if they

coincide with the recorded ones, a signal will be given about successful authorization and actions that symbolize the granting of access will be made.
To control the servomotor, we needed the IDE <Servo.h> supplied with, among others, a description of the Servo class. This class "connects" to the port specified by the number and allows using the attach (int port) and write (int val) methods provided by it to select the port for servo operation and set the position of the servo rotor accordingly.
Fig. 1. Appearance of the result of the assembly As a door opening sensor, a Hall sensor and a large magnet are used in this system. On the principle of the operation of such a bundle in a nutshell: the sensor responds to the magnet being brought to it, which is located on the movable door of the gate, the sensor itself is fixed to the frame[2]. The sensor changes its values depending on the intensity of the magnetic field, that is, the distance to the magnet. Thus, you can monitor the position of the door at any time.
The control panel is equipped with a small LCD-screen for two lines and a button for starting and stopping the security mode, as well as a buzzer and power supply inside. All this is housed in the enclosure for circuit breakers. The hole for the automatics is filed and made a little longer, so that all the characters of the screen will enter there, and the control button will be displayed on the side, see Figure 2.

A twisted pair of 8 conductors emerges from the housing, at the opposite end of which there is a temperature and humidity sensor, a Hall sensor and a piezo-pinch with a button in a separate alarm casing, see Figure 3:

The temperature and humidity sensor notifies about the current climate indoors, and also on the basis of the temperature sensor readings it is possible to learn about a possible fire, since In case of fire, the temperature in the room rises very sharply to higher values above 100 degrees Celsius[3].
The algorithm of signaling is quite simple:
First, an alarm is triggered if the reading from the Hall sensor indicates that the door is closed, the system is silent and periodically checks the readings from the sensor while the alarm is on. If the sensor shows that the door is open, then an alert is triggered, and within a certain time the system will check if the alarm is turned off, if not, then the siren (buzzer) is triggered.
The time delay for the activation of the alarm after pressing and the delay in waiting for the alarm to be turned off can be configured in the program.
It uses an ultrasonic sensor HC-SR04, a buzzer, red, yellow and green LEDs. The essence of this system lies in the fact that the software program determines the safe distance to the object, the permissible distance and the dangerous distance. If the object is at a safe distance from the sensor, the green LED lights up[4]. If it is at an acceptable distance, the yellow LED lights up and the buzzer emits a warning signal, and if at a dangerous distance, the red LED lights up and the buzzer emits a continuous loud alarm.
Having looked through the information received on the following requests:
• Automated security system
• Safety system
• Comprehensive security system
• Bunker with own hands
• Automated bunker
• Security system based on Raspberry Pi
• Security system based on Arduino
• Bunker based on Raspberry Pi
• Bunker based on Arduino
We can conclude that security systems by their nature are the same, and even in complex security, systems there are any limitations in the number of its constituent subsystems.
