Automatic Irrigation System Using Soil Moisture Sensor Block Diagram

The moisture sensor just senses the moisture of the soil.

Automatic irrigation system using soil moisture sensor block diagram.

2 soil moisture sensor. The working of the circuit is as follows. On receiving the signal the microcontroller produces an output that drives a relay and operates the water pump. In this project arduino is used for controlling the whole working of the circuit.

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

Hence the system reduces human intervention and provides required irrigation to field. Depending on the quality of the sensor it must be inserted near the roots of the plant. Also lcd is used which is interfaced with microcontroller for displaying the moisture content of soil and water pump status. 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 working of automatic irrigation system is very simple and easy to understand. The change in moisture is. First of all when there is no moisture present in the soil there will be conduction between two probes of the soil sensor.

In this project we are going to build a transistor based simple soil moisture detector circuit. Then motor water pump supplies water to plants. Temperature sensor has been used for sensing the temperature. The author s prototype is shown in fig.

Automatic plant watering system circuit and working. Moisture sensor and motor water pump. This is very simple and interesting circuit for electronics lovers. Schematic circuit diagram of automatic plant watering irrigation system.

The output of temperature sensor is given to microcontroller. Working of automatic irrigation system. According to this system there are two functional components in this project i e. This soil moisture sensor circuit can be used in many applications like automatic plant irrigation system greenhouse projects etc.

This process is done by a 555 timer. The idea of the project is to implement an automatic irrigation system by sensing the moisture of the soil. Figure 2 1 block diagram of automatic irrigation system figure 2 1 is the block diagram of the automatic irrigation system. The block diagram of this automatic plant irrigation system comprises three main components namely a microcontroller a motor driver circuit and a sensor circuit.
