Arduino Soil Moisture Sensor

https://circuitsnepal.odoo.com/web/image/product.template/62/image_1920?unique=8c9d191

This is a Soil Moisture Sensor or Soil Humidity Sensor. With this module, you can tell when your plants need watering by how moist the soil is in your pot, garden, or yard.

Use it in a home automated watering system, hook it up to IoT, or just use it to find out when your plant needs a little care. Installing this sensor and its PCB will have you on your way to growing a green thumb!

This soil moisture sensor consists of two probes which are used to measure the volumetric content of water. The two probes allow the current to pass through the soil and then it gets the resistance value to measure the moisture value.

Product Description:


The Arduino Soil Moisture Sensor Module is an easy-to-use, efficient tool for monitoring soil moisture levels in your garden, greenhouse, or any other plant-based environment. Whether you're building an automated watering system or simply want to monitor the moisture levels of your soil, this sensor provides accurate readings, making it perfect for Arduino-based projects. It helps optimize water usage, ensuring your plants receive just the right amount of water.

How to Use:

  1. Connect the sensor to your Arduino board (VCC to 5V, GND to GND, and the output to an analog pin like A0).
  2. Insert the sensor into the soil at the desired depth.
  3. Upload the Arduino code to start reading moisture levels from the sensor.
  4. Use the output data to control a watering system or monitor the soil condition.
