Abstract

The peristaltic dosing pump is one of the popular choices of equipment in liquid dispensing system for accurate volume dosing. Peristaltic pump is widely used in chemical dosing in laboratories, beverage industries, laundry machines and many more. In such industries, manual dosing of liquids and chemicals consumes more energy with less efficiency and produces more waste. The project is intended to integrate an eco-friendly peristaltic pump dosing system for precise liquid and chemical dispensing based on controllable pumping parameters and monitor the operation using Internet of Things (IoT). The liquid dispenser is integrated with motor drive, peristaltic pump, signal conditioning circuit and microcontroller connected to the IoT dashboard. The system employs Blynk mobile application to function as a tool to monitor the pump and machines’ status. A signal conditioning circuit is designed to amplify small signal from machine hall sensor and feed into microcontroller digital input. The project also focusses on the analysis to find the optimum point based on several parameters including varying motor speed, duty cycle and pumping time to the output volume dispensed. The system is designed with alert notification features to inform the user on the status of the machine.
