Description

Project not tested

Digital visitor counter is a reliable circuit that takes over the task of counting Number of Persons/ Visitors in the Room very Accurately. When somebody enters into the Room then the Counter is Incremented by one and when any one leaves the room then the Counter is Decremented by One. The total number of Persons inside the Room is displayed on the seven segment displays. The microcontroller do the above job it receives the signals from the sensors, and this signals operated under the control of software which is stored in ROM
