USED COMPONENETS IN THIS PROJECT

Arduino Uno : The Arduino Uno is an open-source microcontroller board designed for prototyping electronic projects, featuring a simple hardware platform and a user-friendly development environment.
Microcontroller : The Arduino Uno is built around the ATmega328P microcontroller from Atmel (now a part of Microchip Technology). This microcontroller operates at 16 MHz and has 32KB of flash memory for storing the program code, 2KB of SRAM for variables, and 1KB of EEPROM for non-volatile data storage.
Flow Rate Measurement : To measure water flow rate.

Relay : A relay is an electrical switch that uses an electromagnet to control the opening and closing of one or more sets of contacts. It is a fundamental component in electrical and electronic circuits and serves various purposes, primarily to control the flow of electrical current between different parts of a circuit. Relays are commonly used to switch high-voltage or high-current circuits with a low-voltage or low-current control signal.

5V Four-Channel Relay Module : The four-channel relay module contains four 5V relays and the associated switching and isolating components, which makes interfacing with a microcontroller or sensor easy with minimum components and connections. The contacts on each relay are specified for 250VAC and 30VDC and 10A in each case, as marked on the body of the relays.

Supply voltage – 3.75V to 6V

Trigger current – 5mA

Current when the relay is active - ~70mA (single), ~300mA (all four)

Relay maximum contact voltage – 250VAC, 30VDC

Relay maximum current – 10A

LCD Display : An LCD display, or Liquid Crystal Display, is a type of flat-panel screen commonly used for displaying visual information in a wide range of electronic devices. LCDs offer several advantages, including low power consumption, thin form factor, and the ability to display sharp and clear images. Here are the key components and characteristics of an LCD display:
RC1602A LCD : RC1602A is a monochrome character LCD module with display format of 16 character x 2 lines. The dimension of the module is 84.0 x 44.0 mm. Default interface is 6800 with built-in IC ST7066; if you require interface such as SPI or I2C, they're also available, but the IC will be replaced with RW1063.

Rain Sensor FC-37 : The rain sensor is used to detect water and it can detect beyond of what a humidity sensor do. This article explains how to use the FC-37 rain sensor module with the Arduino.The FC-37 rain sensor (or other versions like YL-83) is set up by two pieces: the electronic board (at the left) and the collector board (at the right) that collects the water drops, as you can see in the following figure:

12V Micro Submersible Pump : A 12V micro submersible pump is a small water pump designed to be submerged in liquids, typically water, for various applications. These pumps are compact, energy-efficient, and can be powered by a 12-volt DC power source, making them suitable for a wide range of projects where water needs to be moved or circulated. Here are the key features and characteristics of a 12V micro submersible pump.

Rainbow Wire : "Rainbow wire" typically refers to a set of electrical wires, cables, or ribbon cables that come in a variety of colors, resembling the colors of a rainbow. These wires are often used in electronics and electrical projects for several purposes, including organization, identification, and ease of connection. Here are some key characteristics and uses of rainbow wires

Mini Switch : A "mini switch" typically refers to a small and compact electrical switch that is designed for use in various electronic and electrical applications. These switches are often used when space is limited or when a more discreet or low-profile switch is required. Here are some key characteristics and common uses of mini switches:

BreadBoard : A common use in the system on a chip (SoC) era is to obtain an microcontroller (MCU) on a pre-assembled printed circuit board (PCB) which exposes an array of input/output (IO) pins in a header suitable to plug into a breadboard, and then to prototype a circuit which exploits one or more of the MCU's peripherals, such as general-purpose input/output (GPIO), UART/USART serial transceivers, analog-to-digital converter (ADC), digital-to-analog converter (DAC), pulse-width modulation (PWM; used in motor control), Serial Peripheral Interface (SPI), or I²C. Firmware is then developed for the MCU to test, debug, and interact with the circuit prototype. High frequency operation is then largely confined to the SoC's PCB. In the case of high speed interconnects such as SPI and I²C, these can be debugged at a lower speed and later rewired using a different circuit assembly methodology to exploit full-speed operation. A single small SoC often provides most of these electrical interface options in a form factor barely larger than a large postage stamp, available in the American hobby market (and elsewhere) for a few dollars, allowing fairly sophisticated breadboard projects to be created at modest expense.

Bluetooth Arduino : The HC-05 is a commonly used Bluetooth module that allows wireless communication between devices over short distances. It's often used in various electronics projects for tasks such as data transmission, remote control, and wireless communication. Here are some key points about the HC-05 Bluetooth module.
Bluetooth Communication : The HC-05 module is based on Bluetooth technology and is primarily used to enable wireless communication between devices. It follows the Bluetooth 2.0 specification with Enhanced Data Rate (EDR) capabilities.

PVC HOSE PIPE FOR SMALL DC SUBMERSIBLE PUMP : When using a DC submersible pump in a water-based application, such as for irrigation, water supply, or drainage, the choice of pipe is crucial to ensure efficient and reliable operation. Here are some key points to consider when selecting and using pipes for a DC submersible pump
