Automatic Irrigation System Using Arduino Block Diagram

The working of automatic irrigation system is very simple and easy to understand.

Automatic irrigation system using arduino block diagram.

If soil will get dry then sensor senses low moisture level and automatically switches on the water pump to supply water to the plant. Arduino is used for controlling the whole process and gsm. Basically it is a resistor that works on moisture. This below figure 3 1 is a overall block diagram of arduino based automatic irrigation system which consist of three sensors which are connected to controller and sensed values from these sensors are send to the mobile application.

Block diagram of automatic irrigation system. An automated irrigation system using arduino microcontroller by aslinda et al. Working of automatic irrigation system. In this project arduino is used for controlling the whole working of the circuit.

The water pump and servo motor are controlled by arduino connected to digital pins 3 and 9 respectively. Working of this automatic plant irrigation system is quite simple. Background of the system products components specifications arduino based automated plant watering system. Automatic plant watering system full source code circuit free pdf download introduction aim of the project.

The soil moisture sensor is a sensor which varies the value when it contacts the moisture. We are using an arduino microcontroller to control and sense the thing in the projects such as sense or measure the moisture in the soil we are using soil moisture sensor. Below is the circuit diagram of this irrigation system with arduino and soil moisture sensor. Logically as the system has an hour pre set to operate you can change the time via software for the time you will do the tests and after you can adjust the operational time.

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 i will be demonstrating automatic irrigation system with integrated temperature sensor which irrigates or waters your plants automatically this system is best suited for drip irrigation technique. The program in the arduino reads the moisture value from the sensor every 20 seconds. Automatic plant watering block diagram schematic circuit diagram of automatic plant watering irrigation system project design hardware design sensor schematic lcd.

Step 5 arduino automatic watering system tests adjustments below is a picture with an example of how the system works and how the tests should be performed. That is the servo motor signal control pin is connected to pin 9 of the arduino board. A moisture sensor is used to read the moisture content of the soil the lm35 temperature sensor reads the ambient temperature. Circuit diagram of the automatic plants watering system.

In an automatic plant watering system or we can say it smart irrigation system. In this system soil moisture sensor senses the moisture level of the soil. So i have made automatic plant watering system using arduino uno.
