Automatic Irrigation System Using Soil Moisture Sensor Block Diagram

It is an arduino based automatic plant watering system that uses a soil moisture sensor.

Automatic irrigation system using soil moisture sensor block diagram.

Schematic circuit diagram of automatic plant watering irrigation system. The circuit diagram of the automatic plant watering system is shown in fig. The working of the circuit is as follows. Automatic plant watering system circuit and working.

Block diagram of sensor based automatic drip irrigation system 1 temperature sensor. The soil moisture sensor is inserted in the soil. Temperature sensor has been used for sensing the temperature. The soil moisture sensor measures the conductivity of the.

Hence the system reduces human intervention and provides required irrigation to field. In this project arduino is used for controlling the whole working of the circuit. Working of automatic irrigation system. This is very simple and interesting circuit for electronics lovers.

The moisture sensor just senses the moisture of the soil. The change in moisture is. The working of automatic irrigation system is very simple and easy to understand. The idea of the project is to implement an automatic irrigation system by sensing the moisture of the soil.

On receiving the signal the microcontroller produces an output that drives a relay and operates the water pump. When the sensor circuit senses the condition of soil it compares it with the reference voltage 5v. In here the power source provided by the solar panel is being stored in a 12 v battery and then it is converted to dc to ac by the inverter. The output of temperature sensor is given to microcontroller.

In its most basic form moisture sensor senses level of the soil moisture. According to this system there are two functional components in this project i e. Depending on the quality of the sensor it must be inserted near the roots of the plant. Then motor water pump supplies water to plants.

Also lcd is used which is interfaced with microcontroller for displaying the moisture content of soil and water pump status. In this circuit we have used an npn transistor to detect soil moisture. This process is done by a 555 timer. In this project we are going to build a transistor based simple soil moisture detector circuit.

First of all when there is no moisture present in the soil there will be conduction between two probes of the soil sensor. The block diagram of this automatic plant irrigation system comprises three main components namely a microcontroller a motor driver circuit and a sensor circuit. 2 soil moisture sensor. Figure 2 1 block diagram of automatic irrigation system figure 2 1 is the block diagram of the automatic irrigation system.
