Soil Moisture Sensor Arduino Source Code

The analog output voltage boosts along with the soil moisture level increases.

Soil moisture sensor arduino source code. This is a simple arduino project for a soil moisture sensor that will light up a led at a certain moisture level. This tutorial explains how to read soil moisture data using analog soil moisture sensor on arduino platform. Soil moisture sensor arduino. According to the code to control the speed of.

Soil moisture is basically the amount content of water present in the soil. In this tutorial we have used the waveshare soil moisture sensor. When you hear the word smart garden one of the things that pop up to your mind is the automatic measurement of the moisture content of the soil. Robo india offers soil moisture sensor that gives analog signal.

In this system soil moisture sensor senses the moisture level of the soil. It has a fork like design which makes it easy to insert into the soil. The sensor module contains a potentiometer with it which is used to set the threshold value. A comparator activates a digital output when a adjutable threshold is exceeded.

Circuit diagram working explanation and program code for beginners. If soil will get dry then sensor senses low moisture level and automatically switches on the water pump to supply water to the plant. Interfacing soil moisture with arduino uno. To connect the soil moisture sensor fc 28 in the digital mode we will connect the digital output of the sensor to the digital pin of the arduino.

This variable resistor is connected in a voltage divider configuration. If you re building a smart garden that waters plants automatically and give you the readings of the wet. It has a detection length of 38mm and a working voltage of 2v 5v. Arduino pin 13 named as waterpump in code is used to turn on and off the transistor.

This project is about arduino and capacitive soil moisture sensor lcd oled interfacing tutorial. So here in this tutorial we are reading data from analog moisture sensor so we will get reading in the range 0 to 1023. Two wires placed in the soil pot form a variable resistor whose resistance varies depending on soil moisture. This project is designed to monitor the water content of a soil by using soil moisture sensor.

Interfacing soil moisture sensor and arduino. The soil moisture sensor measures soil moisture grace to the changes in electrical conductivity of the earth soil resistance increases with drought. At the time we start writing the code we define 3 variables. Lesser the value means lesser the moisture in soil.
