Infrared object counter circuit Fig. 1: Infrared Object Counter: Transmitter circuit. Powered by a 9V battery, the transmitter circuit (see Fig. 1) comprises IC 555 (IC1), which is wired as an astable ...

Infrared interruption counter stage. The IR interruption counter circuit (Fig. 4) is built around IR receiver TSOP1736 (IRX1) utilising timer NE555 (IC3), 4-digit counter-cum-display driver IC 74C926 ...

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.

For Power supply purposes, I decided to use a 12V DC Power Adaptor to power this whole setup through a barrel jack connector. In the below image, you can find our actual hardware setup of our ...

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. The can be simply divided into ...

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, ...
