This infrared object counter can be installed at the entry gate to count the total number of people entering any venue. For example, it can be used at the railway stations or bus stands to count the ...

Fig. 3: IR transmitter circuit The block diagram of the infrared interruption counter providing an overview of the system is shown in Fig. 1. The astable multivibrator produces 36kHz frequency and npn ...

By using this Circuit, we can increase the range of emitted IR radiation up to 100cm. It means we can increase the IR transmitting distance multiple times using this Long Range IR Transmitter circuit.

Build a Bidirectional Visitor Counter using Arduino and IR sensors to track entry and exit movements with real-time counting on an LCD display. This step-by-step guide covers circuit design, hardware ...

Object counter using 8051 microcontroller. This circuit can count the number of objects passing across a line , number of persons passing through a gate/door and so on.

But the circuit in the figure shows an infrared close-object alert system built around two popular and less expensive integrated circuits: the LM555 timer and CD4060 CMOS, 14-stage, ripplecarrying ...

This Bidirectional Visitor Counter Circuit helps to count the number of people entering or leaving the room, and displays the total count on the screen. It is mainly helpful to use in parties, ...

BLOCK DIAGRAM CIRCUIT DESIGN The above mentioned is the circuit diagram of a simple parking lot counter. Note*: The circuit of IR Module is not mentioned in this diagram. In place of it, an ...
