#SOIL MOISTURE SENSOR HOW TO#

How do you calibrate a soil moisture sensor? Connect the VCC and GND pins to the Microcontroller's 5V and GND pins. Connect the sensor module's Analog/Digital Output pin to the Microcontroller's Analog/Digital pin. It is very simple to use a Moisture sensor module with a Arduino.

#SOIL MOISTURE SENSOR HOW TO#

How to connect a soil moisture sensor module with an Arduino? The fork-shaped probe with two exposed conductors functions as a variable resistor, with resistance varying with soil moisture content.Ģ. This sensor works by inserting the module into the soil.

Soil Moisture sensor mainly uses capacitance to determine the soil's water content.

Soil Moisture Sensor Interfacing With Arduino Unoįrequently Asked Questions 1. Therefore, the moisture level will be lower. Dry soil conducts electricity poorly, so when there will be less water, then the soil will conduct less electricity which means that there will be more resistance. Therefore, the moisture level will be higher. When there is more water, the soil will conduct more electricity which means that there will be less resistance. The two probes allow the current to pass through the soil and then it gets the resistance value to measure the moisture value. The soil moisture sensor consists of two probes which are used to measure the volumetric content of water.

Installing this sensor and its PCB will have you on your way to growing a green thumb! The two probes on the sensor act as variable resistors. 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 love. With this module, you can tell when your plants need watering by how moist the soil is in your pot, garden, or yard. This is Soil Moisture Sensor Module or Soil Moisture Meter, Soil Humidity Sensor, Water Sensor, Soil Hygrometer for Ardunio.
