DESIGN & IMPLEMENTATION OF DATA LOGGER WITH INTEGRATED DISPLAY SYSTEM OF CPLD

This paper presents a method of Real Time Data Logger using CPLD platform. Data logger gives information to management on the volume and flow of people in a location. Important parameter such as visitor counts is acquired through an Infrared LED and Sensor interfacing with CPLD. Counts are analyzed in real time and presented on display depends on the movements in front of IR LED and Sensor. Visitor Counts are determined by the CPLD depending on the output of sensor. CPLD obtain data from sensor and send it to display in parallel form. Counter calibration should be compulsory, repeated regularly and applied before data analysis or reporting. Calibration should be effected with agreed, standard fields of information and clear distinctions must be made between the number of ‘visits’ being measured by a counter and the total number of ‘visitors’. Data logger helps to maximize the effectiveness and efficiency of employees, floor area and sales potential of an organization depending on the number of people visiting the organization.
