The idea of the project is to implement an automatic irrigation system by sensing the moisture of the soil.
Automatic irrigation system using soil moisture sensor block diagram.
The working of automatic irrigation system is very simple and easy to understand.
Automatic plant watering system circuit and working.
When the sensor circuit senses the condition of soil it compares it with the reference voltage 5v.
The soil moisture sensor measures the conductivity of the.
The change in moisture is.
Temperature sensor has been used for sensing the temperature.
Working of automatic irrigation system.
This is very simple and interesting circuit for electronics lovers.
Depending on the quality of the sensor it must be inserted near the roots of the plant.
It is an arduino based automatic plant watering system that uses a soil moisture sensor.
The moisture sensor just senses the moisture of the soil.
The author s prototype is shown in fig.
Figure 2 1 block diagram of automatic irrigation system figure 2 1 is the block diagram of the automatic irrigation system.
Moisture sensor and motor water pump.
This process is done by a 555 timer.
In its most basic form moisture sensor senses level of the soil moisture.
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.
2 soil moisture sensor.
In this project we are going to build a transistor based simple soil moisture detector circuit.
According to this system there are two functional components in this project i e.
On receiving the signal the microcontroller produces an output that drives a relay and operates the water pump.
The circuit diagram of the automatic plant watering system is shown in fig.
This soil moisture sensor circuit can be used in many applications like automatic plant irrigation system greenhouse projects etc.
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.
Schematic circuit diagram of automatic plant watering irrigation system.
First of all when there is no moisture present in the soil there will be conduction between two probes of the soil sensor.
Block diagram of sensor based automatic drip irrigation system 1 temperature sensor.
The soil moisture sensor is inserted in the soil.
The block diagram of this automatic plant irrigation system comprises three main components namely a microcontroller a motor driver circuit and a sensor circuit.
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.
