The goal of this project is to build and implement an Rf-based wireless batch counting system for a brewery that can count the bottled products on the conveyor and display the value numerically and wirelessly to a receiver that is roughly 100 meters distant. The transmitter and receiver units are the two functional units that make up this project. The transmitter unit is positioned on the conveyor, while the receiver unit is located elsewhere. They communicate via the radio frequency transmission waveband and the theory of electrical resonance. The sensor/electronic eye detects the presence of a bottle using an opto-coupler made up of a Light dependent Resistor (LDR) and a Laser diode. The sensor unit’s output signal is analyzed and used to cause the TRF transmitter module to emit an Rf signal to its receiver, which is several meters away. The output of the received signal is analyzed and used to clock a 2-digit decimal counting unit that numerically displays the number of counted bottles. This system has a lot of implications in terms of computers and EEE. If the recorded value is not equal to the single unit version likewise installed in the front end of the conveyor as a surveillance system, the personnel involved will be fired. This system can only communicate with the receiver within a 100-meter range. If the recorded value on the stand alone type is smaller than the value recorded by this system at the end of each production cycle, the workers are queried. The end result is a system that can count the number of bottled drinks and wirelessly transmit the number/value to a receiver located a few meters away. It is pure random logic, not microprogram control.




Because of the high rate of industrial espionage and theft, industrial security systems must be strengthened in order to prevent and combat pilfering. This project aims to implement a better security solution that can be utilized to prevent pilfering in the brewery industry. Theft of bottled beverages is a typical occurrence in breweries. And this crime is committed on the conveyor before it is recorded by a solitary counting device. This has a huge impact on the fire’s status, and if it isn’t dealt with properly, it could lead to the firm’s liquidation and bankruptcy.  Normally, a batch counting equipment counts the bottled drinks and shows the values numerically at the same location where carrier criminals divert the products before the counter. This timeline of social vices in the beer sector has inspired me to work on a device that can count/the bottled drinks in the conveyor and show the value numerically and wirelessly (using Rf transmission waveband) to a receiver about 100 meters distant. Before it gets to the standalone version, this device will count the product. This method will aid in the detection of pilfering and the prevention of industrial espionage.


Workers in breweries all around the world face the problem of product pilfering, which occurs most commonly in the conveyer. This threat prompted the creation of a stand-alone batch counting system, which is often put in conveyors to track the overall amount of bottled products. The bad-eggs pilfer/divert the products before they reach the counter, putting this strategy in jeopardy.

Due to the aforementioned issues, it is necessary to build a system that will be deployed at the conveyor entry point to count the items without the consent of the workers and show the value to a receivers unit installed in the manager’s office using radio-frequency technology.


The goal of this project is to build and implement a radio frequency-based wireless batch counter that can count and display bottled drinks/products from a distance.

1. Create a system that uses radio frequency technologies to communicate.

2. To create an opto coupler module that uses a laser diode and visible light to identify opaque items such as bottles.

3. Create a two-digit decimal counting unit that can count from 00 to 99.

4. To create a system that is entirely hardwired. There is no micro-program.

5. Create a power supply unit capable of powering Rf devices.



This project work has a lot of significance in the fields of telecommunications, computer, and electronic engineering. It can be used in a variety of residential settings, such as bedrooms and security lamps in the property. If improved, this project might be used as a gate/door opener, car immobilizer, or industrial process controller. This system also plays a critical role in the control of air conditioners, freezers, and other lamps in modern buildings. This technique can be used to remotely start and stop a power generator.


Tuned Radio-frequency transmitter and receiver modules, Ne555 timer, Decimal counting unit, Decoders and transistors, and electromagnetic relay are all covered in this project. It also places a strong emphasis on the system’s passive and active components. It also reveals the method for calculating the basic parameters utilized in the device’s design and other applications. This study delves deeper into the system’s block diagram and operating concept.


This project report is divided into six chapters to clearly show the stages involved in its execution. The first chapter introduces the project’s design overview, objectives, and significance. The second chapter consists primarily of a literature review and some design-related theories. The system design analysis is discussed in Chapter 3, and the implementation, testing, and results are discussed in Chapter 4. Finally, in chapter five, the complete thesis and recommendations are summarized.
