Automatic Irrigation System Using Soil Moisture Sensor Circuit Diagram

The output from the probe of the moisture sensor is compared with a reference value using a lm393 comparator.

Automatic irrigation system using soil moisture sensor circuit diagram.

Then motor water pump supplies water to plants. This can be changed by implementing a pot in place of one of the resistors connected to the non inverting terminal of the comparator. It will not only automatically irrigate the water based on the moisture level in the soil but also send the data to thingspeak server to keep track of the land condition. Circuit design of auto irrigation system using soil moisture.

Here we are building a iot based irrigation system using esp8266 nodemcu module and dht11 sensor. Schematic circuit diagram of automatic plant watering irrigation system according to this system there are two functional components in this project i e. The smart irrigation system has wide scope to automate the complete irrigation system. The working of automatic irrigation system is very simple and easy to understand.

The automatic irrigation system on sensing soil moisture project is intended for the development of an irrigation system that switches submersible pumps on or off by using relays to perform this action on sensing the moisture content of the soil. In this project we are going to build a transistor based simple soil moisture detector circuit. If the soil moisture sensor is not available the following circuit can be used as an alternative. Introduction the proposed system can monitor the soil moisture level and when soil moisture goes below preset value the 12v dc pump will be triggered for predetermined period of time.

Circuit diagram automatic irrigation system using arduino the soil moisture sensor module used here have two output pins digital output and analog output. The circuit shown below has a fixed sensitivity. In its most basic form moisture sensor senses level of the soil moisture. This soil moisture sensor circuit can be used in many applications like automatic plant irrigation system greenhouse projects etc.

In this post we are going to construct an automated water irrigation system for small garden using arduino and soil moisture sensor. This is very simple and interesting circuit for electronics lovers. Working of automatic irrigation system. In this project arduino is used for controlling the whole working of the circuit.

First of all when there is no moisture present in the soil there will be conduction between two probes of the soil sensor. This project uses an 8051 microcontroller which is programmed in keil software.
