Circuit Documentation

Summary

This circuit is designed to control a relay module, a water flow sensor, multiple DS18B20 temperature sensors, a diaphragm water pump, and a fan using multiple Arduino UNO R4 WiFi microcontrollers. The relay module is used to switch various devices, including adjustable ball valves (kogelkraan), on and off. The water flow sensor monitors the flow rate in the system. The temperature sensors provide temperature readings from different points in the circuit. The diaphragm water pump and fan are controlled by the Arduino through a motor driver. Power is supplied to the components through dedicated power supplies.
