Description
Atoraa’s people counting sensor (A9-PCS) is used to count the number of people passing by the sensor. The A9-
PCS will detect the direction of movement, and will increase / decrease the internal counter value (8 bit). The counter is
implemented as auto roll-over. So it will increment from 255 to 0, and decrement from 0 to 255. The A9-PCS is supplied
by two internal 1.5 V AA batteries. The innovative power saving technology will allow the A9-PCS to work at least 5 years
without any maintenance / changing the batteries.
