Circuit Documentation

Summary

This circuit is designed to interface an ESP8266 microcontroller with a Gravity Analog Water Pressure Sensor and a water flow sensor. The circuit is powered by a 5V adapter. The ESP8266 reads the analog signal from the water pressure sensor and the digital signal from the water flow sensor. The sensors and the microcontroller share a common power supply and ground.
