Abstract - The automatic fluid dispenser introduces a
integration with cooling, heating, and plumbing systems enhances usability [7]. Available in various models—like wall-mounted or direct-piping—these dispensers promote hygiene and efficiency [8]. In small-scale industries, automation reduces human error, spillage, and delays common in manual bottle-filling processes [9]. With IoT advancements, smart systems now enable app-based fluid dispensing, enhancing hygiene and minimizing contact [10]. For instance, IoT-driven mocktail dispensers can mix drinks via automated pumps based on customer orders [11]. Juice mixer machines also reduce labor costs and improve accuracy by preventing over-pouring [12], while more advanced systems like CAMS offer modular, scalable cocktail automation with precise control [13]. In broader applications—such as labs, households, and industries— automated dispensers ensure consistent measurement and efficient operation [14]. Moreover, automated oil filling systems address issues like leakage and inconsistent volume in small-scale production units [15].
systematic and efficient alternative to manual fluid dispensing and expensive industrial systems like those from Nordson EFD. These high-end solutions, while precise, are often costly and lack flexibility, making them inaccessible for many applications. This project presents a cost-effective, microcontroller-based dispenser that accurately controls the speed and duration of a peristaltic pump to ensure precise, contamination-free fluid delivery. It is especially beneficial in sectors like pharmaceuticals, food and beverage, chemicals, cosmetics, and research, where accurate dosing is critical. By automating the process, it reduces manual effort, prevents health risks, ensures quality, and minimizes resource wastage, offering a reliable solution for precision fluid dispensing. Key Words: Liquid dispensing systems, peristaltic pumps, LCD, motors, relays, liquid medication.
1.INTRODUCTION
2. RELATED RESEARCH
Fluid dispensing is essential in many industries, including healthcare, manufacturing, and food processing, and cosmetics where precise and consistent liquid handling is critical. The traditional method of fluid dispensing is very time-consuming and prone to human errors as it requires fluids are dispensed manually after measurement. The ability to dispense exact volumes of fluids impacts product quality, safety, and efficiency, making it a key focus in settings that range from administering medications to applying adhesives in production lines. It also results in wastage of resources making the process inexpensive. Despite its importance, fluid dispensing faces several challenges that complicate its effectiveness and reliability. Water is vital for human survival, yet only 0.08% of Earth’s freshwater is accessible for use [1]. Rising demand and shrinking resources have intensified global water scarcity. According to the International Water Management Institute, by 2025, most regions in Latin America, Asia, Africa, and the Middle East may face severe shortages [2]. Overexploitation, blocked basins, and poor management practices have further reduced water availability [3]. Modern solutions like agricultural reforms and rainwater harvesting are urgently needed [4], especially as groundwater resources continue to decline [5]. Technological innovations such as coin-operated water dispensers help minimize wastage by enabling controlled and automated distribution [6] , and their

An automatic fluid dispenser is a device designed to dispense a specific amount of fluid, such as soap, sanitizer, or other liquids, without manual intervention. These systems are often employed in public facilities, healthcare settings, and households to promote hygiene and reduce the spread of germs. With the advent of automation, fluid dispensers have evolved to include sensors, microcontrollers, and advanced mechanisms to enhance precision and reliability. Anita Joshi et al. [1] developed an Arduino-based automated liquid dispenser aimed at delivering precise liquid measurements using sensors, pumps, and valves. Kiran Patil et al. [2] implemented a similar system with an IR sensor, solenoid valve, and pump to dispense accurate amounts of liquid efficiently. Ayush Vats et al. [3] proposed a smart dispenser equipped with an LCD and Arduino, targeting safe and accurate fluid handling in medical applications. Chaitanya Salunkhe et al. [4] presented a customizable multi-liquid dispenser using microcontrollers and solenoid valves. Kalpana M. and Snehal B. [5] designed a smart beverage dispenser with Arduino and a GSM module to reduce manual intervention. Isha Sharma et al. [6] developed a voice-controlled dispenser using a voice recognition module, making it accessible for differentlyabled users. Pooja Pawar et al. [7] introduced an automated
