Automatic Irrigation System Using Soil Moisture Sensor Block Diagram

In its most basic form moisture sensor senses level of the soil moisture.

Automatic irrigation system using soil moisture sensor block diagram.

Automatic plant watering system circuit and working. 2 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. Also lcd is used which is interfaced with microcontroller for displaying the moisture content of soil and water pump status.

The output of temperature sensor is given to microcontroller. This process is done by a 555 timer. The soil moisture sensor measures the conductivity of the. Moisture sensor and motor water pump.

On receiving the signal the microcontroller produces an output that drives a relay and operates the water pump. This soil moisture sensor circuit can be used in many applications like automatic plant irrigation system greenhouse projects etc. The working of the circuit is as follows. The change in moisture is.

The moisture sensor just senses the moisture of the soil. The working of automatic irrigation system is very simple and easy to understand. Working of automatic irrigation system. This is very simple and interesting circuit for electronics lovers.

The block diagram of this automatic plant irrigation system comprises three main components namely a microcontroller a motor driver circuit and a sensor circuit. According to this system there are two functional components in this project i e. Temperature sensor has been used for sensing the temperature. The soil moisture sensor is inserted in the soil.

Hence the system reduces human intervention and provides required irrigation to field. The circuit diagram of the automatic plant watering system is shown in fig. When the sensor circuit senses the condition of soil it compares it with the reference voltage 5v. In this project arduino is used for controlling the whole working of the circuit.

Then motor water pump supplies water to plants. Figure 2 1 block diagram of automatic irrigation system figure 2 1 is the block diagram of the automatic irrigation system. Depending on the quality of the sensor it must be inserted near the roots of the plant. The idea of the project is to implement an automatic irrigation system by sensing the moisture of the soil.

In this circuit we have used an npn transistor to detect soil moisture. It is an arduino based automatic plant watering system that uses a soil moisture sensor. The author s prototype is shown in fig. 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.
