Automatic Irrigation System Using Microcontroller Circuit Diagram

Soil have high resistance when it is dry and has very low resistance when it is wet.

Automatic irrigation system using microcontroller circuit diagram.

Nowadays farmers are struggling hard in the agricultural fields round the. We use the basic concept in this circuit i e. Working of automatic irrigation system. The main function of solar panels is to convert solar energy into dc electrical energy generally of 12v which is further used for the rest of the circuit.

The block diagram of this automatic plant irrigation system comprises three main components namely a microcontroller a motor driver circuit and a sensor circuit. Then motor water pump supplies water to plants. The circuit is designed to work automatically and hence there is no need for any human intervention. In this project arduino is used for controlling the whole working of the circuit.

By using this concept we will make the system work. Now change the two values in the program 1 the amount of time will take to water all the plants in minutes. When the sensor circuit senses the condition of soil it compares it with the reference voltage 5v. In its most basic form moisture sensor senses level of the soil moisture.

The working of automatic irrigation system is very simple and easy to understand. Moisture sensor and motor water pump. I have explained main components of this project also along with circuit diagram. The project is intended for small gardens and residential environment.

Circuit diagram of solar power auto irrigation system is given below. An automated irrigation system using arduino microcontroller by aslinda et al. How to calibrate this automatic irrigation system. Gsm based automatic irrigation system.

These panels are designed with solar cells composed of semiconductor materials. 2 threshold level below which the arduino triggers the pump. First of all when there is no moisture present in the soil there will be conduction between two probes of the soil sensor. Circuit diagram of solar power auto irrigation system using pic microcontroller.

Automatic plant irrigation system. Schematic circuit diagram of automatic plant watering irrigation system. Block diagram of automatic plant irrigation system. Block diagram of automatic solar submersible pump control for irrigation solar panel.

According to this system there are two functional components in this project i e. By using advanced soil moisture sensor the same circuit can be expanded to large agricultural fields. Circuit is not that much complicated. The lcd displays the condition of the pump on or off interfaced to the microcontroller.
