Automatic Irrigation System Using Soil Moisture Sensor Block Diagram

Hence the system reduces human intervention and provides required irrigation to field.

Automatic irrigation system using soil moisture sensor block diagram.

The moisture sensor just senses the moisture of the soil. Automatic plant watering system circuit and working. Also lcd is used which is interfaced with microcontroller for displaying the moisture content of soil and water pump status. The working of the circuit is as follows.

2 soil moisture sensor. Depending on the quality of the sensor it must be inserted near the roots of the plant. In this project we are going to build a transistor based simple soil moisture detector circuit. The idea of the project is to implement an automatic irrigation system by sensing the moisture of the soil.

When the sensor circuit senses the condition of soil it compares it with the reference voltage 5v. This soil moisture sensor circuit can be used in many applications like automatic plant irrigation system greenhouse projects etc. Schematic circuit diagram of automatic plant watering irrigation system. The working of automatic irrigation system is very simple and easy to understand.

The soil moisture sensor measures the conductivity of the. Working of automatic irrigation system. Figure 2 1 block diagram of automatic irrigation system figure 2 1 is the block diagram of the automatic irrigation system. 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 block diagram of this automatic plant irrigation system comprises three main components namely a microcontroller a motor driver circuit and a sensor circuit. Block diagram of sensor based automatic drip irrigation system 1 temperature sensor. The author s prototype is shown in fig. In this circuit we have used an npn transistor to detect soil moisture.

According to this system there are two functional components in this project i e. It is an arduino based automatic plant watering system that uses a soil moisture sensor. Moisture sensor and motor water pump. In its most basic form moisture sensor senses level of the soil moisture.

The output of temperature sensor is given to microcontroller. The change in moisture is. Then motor water pump supplies water to plants. Temperature sensor has been used for sensing the temperature.

In this project arduino is used for controlling the whole working of the circuit. 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. The soil moisture sensor is inserted in the soil.
