8-channel approach to IR detector sensor circuit is realized with ATmega8 microcontroller. I2C bus (TWI, SMBus) are measuring through the obstacle detection, designed for mobile robot. Approach reflects the beam of infrared light detector circuit based on monitoring works.
8-channel detection information;
Measuring principle: Infrared light reflection Detection
Max. Sensor: 8 independent sensor
Communication interface: I2C – 7bit address
Module size: 78 x 62 mm (3 “x 2.44”)
Measuring the number of degrees: 3 distance levels (Min, Mid, Max)
Supply voltage: +5 V (DC)
Current consumption: 15 mA
Microprocessor: ATMEGA8 ATMEL (AVR – 8MHz)
ATMEGA8 proximity dedector
The aim of this work was to design and implement hardware detector proximity and provide adequate control program, which will be carried out measurements and the results transmitted to the request nadrazenému Management System, through the I2C bus (TWI, SMThe module is designed for educational mobile robot, as detector barriers to the robot unknown environment. With help of a signal can be further processed such as neural networks.

Central Security System with pic16f877
Circuit Operation: PIC16F877 used in the circuit of the B and D as input port is selected. 8 of these units with port B doors, windows and etc.. from places logic 1 or 0 state is evaluated. D port is necessary for system operation or stopping the input of a predetermined password has been supplied. A and C are chosen as output port with port status LEDs and alarm circuit has been. C port to the B port is where you get the warning from the 7 segment LED display is used as the indicator showing. Instead of port 1 LED alarm circuit 1 or 0 is used to determine whether, enter the password warning LED LED 2, 3 the password is correct, and that LED LED LED yandıkd 4 seconds after the system is activated. 4 LED lights up when the system stops enter the password.
