A soil moisture sensor is a practical module that measures the amount of water in the soil to determine the irrigation needs of plants. There are two common types on the market, the classic resistive and the capacitive, which have a much longer life against liquid contact/corrosion. The classic models usually come with an LM393 board and provide both analog (A0), which indicates the humidity level, and digital (D0) output, which is triggered according to a threshold set with a potentiometer. Fully compatible with Arduino and ESP series boards, they are indispensable in automatic pot watering, smart agriculture and greenhouse automation projects.

ESP 32 Smart Plant Watering System
In this project, an automatic plant watering system was developed using an ESP32 and a soil moisture sensor. The sensor continuously measures the soil’s moisture level. When the moisture level drops below a specified threshold, the ESP32 activates the relay to turn on the water pump and water the plant. When the soil is sufficiently moist, the pump automatically stops. Thanks to this project, plants can be watered regularly, and water can be conserved. _______________________________ Connections
