Automatic Irrigation System Using Soil Moisture Sensor Block Diagram

Schematic circuit diagram of automatic plant watering irrigation system.

Automatic irrigation system using soil moisture sensor block diagram.

The working of the circuit is as follows. The output of temperature sensor is given to microcontroller. The working of automatic irrigation system is very simple and easy to understand. The change in moisture is.

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 author s prototype is shown in fig. The circuit diagram of the automatic plant watering system is shown in fig. In this circuit we have used an npn transistor to detect soil moisture.

The idea of the project is to implement an automatic irrigation system by sensing the moisture of the soil. This process is done by a 555 timer. Moisture sensor and motor water pump. 2 soil moisture sensor.

In this project arduino is used for controlling the whole working of the circuit. 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. It is an arduino based automatic plant watering system that uses a soil moisture sensor.

First of all when there is no moisture present in the soil there will be conduction between two probes of the soil sensor. Temperature sensor has been used for sensing the temperature. This is very simple and interesting circuit for electronics lovers. In its most basic form moisture sensor senses level of the soil moisture.

On receiving the signal the microcontroller produces an output that drives a relay and operates the water pump. Block diagram of sensor based automatic drip irrigation system 1 temperature sensor. Figure 2 1 block diagram of automatic irrigation system figure 2 1 is the block diagram of the automatic irrigation system. Hence the system reduces human intervention and provides required irrigation to field.

The block diagram of this automatic plant irrigation system comprises three main components namely a microcontroller a motor driver circuit and a sensor circuit. The moisture sensor just senses the moisture of the soil. The soil moisture sensor is inserted in the soil. In this project we are going to build a transistor based simple soil moisture detector circuit.

Automatic plant watering system circuit and working. Depending on the quality of the sensor it must be inserted near the roots of the plant. According to this system there are two functional components in this project i e. When the sensor circuit senses the condition of soil it compares it with the reference voltage 5v.
