In today's era when precise, accurate and timeefficient systems are in great demand, automated techniquessupersede manual practices. As a need of time, we introduce awireless, automated, cost effective, yet reliable and efficientsystem of fluid dispensing. Our prototype system can dispensevarying amounts of fluids in milliliters (maximum 1L) as perdemand of the user. It uses the principle of time based fluiddispensing achieved through the built-in timer property of theAT89C51 microcontroller. To satisfy the principle used andverify the system's accuracy, fluids of varying viscosities weredispensed and monitored. The experimental results of thewireless fluid dispensing system when tested showed linearrelationship between the dispensing time and desired volumes offluids having differing viscosities. The added feature of wirelesscontrol using HM-TRP series transceiver module along with onsitecontrol via a keypad eliminated the need of physical presenceof operator within the range of 10 meters in order to make thesystem operational. This system can be used in pharmaceuticaland beverage industries as well as in different laboratories fordispensing and filling volumes of fluids with varying viscosities.
