Soil Moisture Sensor

A soil moisture sensor is an electronic sensor used to detect the moisture level in soil. It measures the amount of water present in the soil and provides a signal that can be read by a microcontroller such as an Arduino UNO or Arduino Mega. It is commonly used in automatic irrigation systems, smart farming projects, plant monitoring, and STEAM projects. The sensor can help determine when the soil is dry and automatically activate a water pump to provide water to plants.
