Circuit Documentation

Summary

This circuit is designed to monitor water pressure and flow using an Arduino UNO, a Gravity: Analog Water Pressure Sensor, a water flow sensor, and an ESP8266 module. The circuit is powered by a 5V adapter. The Arduino UNO reads the sensor data and can communicate with the ESP8266 for potential wireless data transmission.
