Design and Implementation of a Chemical Solutions Mixing Module

This lecture covers the design and implementation of a module for mixing and regulating chemical solutions, specifically nutrient solutions for vertical agriculture. Topics include developing a hydraulic system, automating the system, diluting nutrients with water, sizing reservoirs, selecting appropriate pumps, calculating pump flow rates, and integrating the system into the overall project. The lecture also delves into the electronic system components such as peristaltic and submersible pumps, mixers, Arduino boards, relays, pH meters, EC sensors, and power supplies. The program logic for controlling the pumps and mixer is discussed in detail, along with the code snippets for pump activation and deactivation based on the desired solution type.
