Automatic Watering System To Plants By Using Arduino Mega 2560

In my last article, I explained about controlling Light/Fan using Arduino Mega 2560. Now I will explain about the Automatic Watering System on plants using Arduino Mega 2560.

Introduction

• In this article, I will explain about the Automatic Watering System to plants using Arduino Mega 2560.
• It can be very useful for maintaining the plants.
• It will monitor the plants at the correct time and give the status of the plants.

• Arduino Mega 2560
• Soil moisture sensor
• Bluetooth
• Motor
• Led
• GSM-Module
• Bread Board
• Hook up wires

• GSM means Global System For Mobile and it can be used to send and receive a message in critical areas.
• It can also act as a GSM modem.
• It can have a PIN configuration and MIC is also attached.

• Soil moisture sensor is used to measure the volumetric water in the soil.
• It measures the free soil moisture requiring removing, drying, and weight of a sample.
• It consists of two pins only.

• It can be used to design the transparent wireless serial connection setup.
• HC-05 module is easy to use Bluetooth SSP.

• Connect the RX pin of the GSM board to the RX1 of the Arduino Mega 2560.
• Connect the TX pin of the GSM board to the TX1 of the Arduino Mega 2560.
• Connect the 5V power supply to the Arduino Mega 2560.
• At last, connect the GND to the GSM board.

• Vcc pin to the 5v
• Gnd to Gnd
• Data pin to the Analog A0

• RX to TX
• TX to RX
• Vcc to Arduino 5v
• Gnd to Gnd

• Connect the positive pin in digital pin 5 in Arduino Mega 2560
• Connect the negative pin in the GND to Arduino Mega 2560.
