ESP8266 Plant Watering - Part 2/3 - Day 41 of

I explain and show step by step how to build a plant watering system with ESP8266, capacitive soil moisture sensor, and peristaltic pump.
During the second day of working on this project, I figured out how to use a capacitive moisture sensor to get the readings from the soil.
