HARDWARE DEVELOPMENT

NODEMCU ESP32

The ESP32 is a versatile and powerful microcontroller and wireless communication module developed by Espressif Systems. It integrates a dual-core processor, Wi-Fi, Bluetooth, and a rich set of peripherals, making it suitable for a wide range of applications in the Internet of Things (IoT), home automation, and embedded systems. With its low power consumption, compact size, and affordability, the ESP32 has gained popularity among developers for building connected devices that require wireless connectivity and processing capabilities.

SOIL MOISTURE SENSOR

A soil moisture sensor is a device designed to measure the water content in soil. It typically consists of probes that are inserted into the soil, and the sensor provides data indicating whether the soil is dry, moist, or saturated.Soil moisture sensors play a vital role in conserving water resources and optimizing plant health by ensuring that plants receive the appropriate amount of water based on the soil's actual moisture levels.

DHT11

The DHT11 is a low-cost digital temperature and humidity sensor commonly used in electronics and IoT projects. It features a compact design with a built-in resistive humidity sensor and a thermistor for temperature measurement. The DHT11 communicates over a single-wire digital interface, making it easy to integrate into various projects, and its affordability makes it a practical choice for hobbyists and developers seeking basic environmental sensing capabilities.

DC3-5V WATER PUMP

The Arduino Vertical Small Submersible Water Pump DC3-5V is a compact and versatile water pump designed for submersible applications, particularly compatible with Arduino microcontrollers. Operating within the DC voltage range of 3-5V.

LCD 1602 DISPLAY

The LCD 1602 display is a widely used alphanumeric liquid crystal display module with 16 columns and 2 rows of characters. The "1602" denotes its capacity to display 16 characters per line over two lines. With an integrated HD44780 controller, it offers a straightforward interface for displaying information, making it suitable for applications like temperature displays, digital clocks, or any project requiring basic textual information output. 

5V RELAY MODULE

The 5V Single Channel Relay is an electronic switch module for controlling high-power devices with a 5V input. Ideal for home automation and electronics projects, it provides isolation between low-voltage control signals (from a microcontroller) and high-power loads, ensuring safety. Its single-channel design makes it straightforward for applications requiring control of a single electrical load, such as lights or motors.

9V BATTERY

A 9-volt (9V) battery is a compact, lightweight power source that's frequently used to supply electricity to different kinds of electronic devices. Its main job is to provide these devices with a steady, dependable voltage. The intended voltage of a 9V battery is to be always roughly 9 volts. Both the positive and negative terminals of the battery provide this voltage, which is largely stable as the battery drains.
