Digital visitor counter is a reliable circuit that takes over the task of counting Number of Persons/ Visitors in the Room very accurately. When anybody 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 microprocessor do the above job it receives the signals from the sensors, and this signals operated under the control of software which is stored in the Memory. The sensors are made with help of LDRs which are Light Dependent Resistors, whose Resistance is inversely proportional to the Light falling on it. The Laser Torch is used as the Light source and it is focused on the LDRs, the Microprocessor continuously watches the LDRs.
