Wireless USB Patron Counter

This completely wireless people counting system is a reliable, user-friendly, and affordable tool providing libraries with accurate count information.

When a patron breaks the bidirectional infrared beams between the transmitter and receiver, the count increases by one. Data is stored in the Counter and extracted via a USB Port using a thumb drive and then downloaded to a PC.

SensorServer software allows librarians to analyze the data by hour, day, week, month, and year in table or graph form. Data can be downloaded as a csv file for viewing and manipulation in Excel. This valuable information reveals peak traffic periods to determine optimal operating hours and staffing requirements.
