Automatic Irrigation System Using Soil Moisture Sensor Circuit Diagram

This project uses an 8051 microcontroller which is programmed in keil software.

Automatic irrigation system using soil moisture sensor circuit diagram.

In this post we are going to construct an automated water irrigation system for small garden using arduino and soil moisture sensor. Schematic circuit diagram of automatic plant watering irrigation system according to this system there are two functional components in this project i e. This is very simple and interesting circuit for electronics lovers. 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.

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. This can be changed by implementing a pot in place of one of the resistors connected to the non inverting terminal of the comparator. Circuit design of auto irrigation system using soil moisture. The circuit shown below has a fixed sensitivity.

The smart irrigation system has wide scope to automate the complete irrigation system. In this circuit we have used an npn transistor to detect soil moisture. Here we are building a iot based irrigation system using esp8266 nodemcu module and dht11 sensor. In this project arduino is used for controlling the whole working of the circuit.

If the soil moisture sensor is not available the following circuit can be used as an alternative. First of all when there is no moisture present in the soil there will be conduction between two probes of the soil sensor. 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. The block diagram of automatic irrigation system on sensing soil moisture content project comprises three main components namely an 8051 microcontroller comparator and relay.

Moisture sensor and motor water pump. The output from the probe of the moisture sensor is compared with a reference value using a lm393 comparator. 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.

The working of automatic irrigation system is very simple and easy to understand. Working of automatic irrigation system.
