| dc.description.abstract | Monitoring and counting of people is very popular in many commercial and non-commercial scenarios. The number of people entering and leaving shops, the occupancy of office buildings, companies, museums or libraries provides useful information to shop merchants and marketers, security officials or the human resource officials the statistics of occupancy. This project develops a monitoring and counting device which uses suitable algorithms and fuzzy rules to implement on. PIR Am412 sensors. For evaluation, a prototyping processor board and relatively low-cost PIR sensors were used to build two sensor nodes from commercially available components. A feature of this implementation is that each sensor node is able to count, on-system and in real-time, the number of passers-by going in each direction, while requiring relatively little compute power. The sensors network is described to monitor the count the number of people entering and leaving a room then update these data on a screen. To enable the configuration of the sensor nodes to specific installation scenarios, and for the purpose of performance analysis, a validation framework is presented. Motion detection is the process of detecting a change in position of an object relative to its surroundings or the change in the surroundings relative to an object. Motion detection can be achieved by both mechanical and electronic methods. The mechanical motion detection is in the form of a switch or trigger while the electrical motion detection is identified are optical detection and acoustical detection. Infrared light or laser technology may be used for optical detection. Motion detection devices like PIR motion detectors have a sensor that detects a disturbance in the infrared spectrum, such as a person or an animal. Once detected, an electronic signal can activate a system or a camera that can capture an image or video of the movement.This project focuses on using motion detectors to develop fuzzy rules and suitable algorithms which are then applied to build a room occupancy and counting device. The overall project is divided into two parts namely the hardware development and the software programming. In the hardware structure, all the electronic components are connected via circuit design i.e. the motion detectors/sensors are the input components while the screen (display) is the output component as it is controlled by a controller circuit (microcontroller). The second part is based on software development (programming) to operate the hardware structure. Programs based on fuzzy rules and suitable algorithms are used on the microcontroller which assembles the code to get the binary file then loads it into an external memory of the hardware structure via the serial communication. This process of transferring and executing the program is done using HyperTerminal’s communication software to the microcontroller serial port. The best room occupancy and counting device is obtained by connecting more motion detectors or sensors to the microcontroller’s output port. Based on the conditional statements in the algorithms, programs using software like MATLAB command and COOCOX COIDE codes that enables the microcontroller to control the counting process as the motion sensors detect motion. | en_US |
