ESP32-WROOM-32 E:

ESP32-WROOM-32E is a powerful, generic Wi-Fi + Bluetooth + Bluetooth LE MCU module that targets a wide variety of applications. Ranging from low-power sensor networks to the most demanding tasks, such as voice encoding, music streaming, and MP3 decoding.

Relay:

A relay is an electrically operated switch. It consists of a set of input terminals for single or multiple control signals, and a set of operating contact terminals.

Buzzer:

Buzzer is a kind of voice device that converts audio models into sound signals. It is mainly used to prompt or alarm

Display:

This is a 1.3-inch blue OLED display module. The display module can be interfaced with any microcontroller using SPI/IIC protocols. It is having a resolution of 128×64. The package includes a display board, a display, and a 4-pin male header pre-soldered to the board.

MicroSD Card Slot:

A Micro Secure Digital slot (MicroSD slot) is a small expansion slot located in mobile and other portable devices. It facilitates the increase of available memory via the insertion of a MicroSD card.

I/O:

I/O describes any operation, program, or device that transfers data to or from a computer.

User LED:

USER LED (Light Emitting Diode) is an electronic device, which emits light when the current passes through its terminals

pH sensor:

A pH sensor is a device used to measure the acidity or alkalinity of a solution. It measures the hydrogen ion concentration (pH) in a solution and converts the reading into a voltage that can be read by a microcontroller or other electronic device. pH sensors are commonly used in applications such as water treatment, agriculture, food and beverage production, and scientific research. They are typically made of a glass electrode and a reference electrode that is immersed in the solution being tested. The glass electrode measures the pH of the solution, while the reference electrode provides a stable voltage reference. pH sensors can provide accurate and reliable readings when calibrated properly, and are an essential tool in many industries and fields of study.

TDS Sensor:

A TDS meter is a small hand-held device used to indicate the Total Dissolved Solids in a solution, usually water. Since dissolved ionized solids, such as salts and minerals, increase the conductivity of a solution, a TDS meter measures the conductivity of the solution and estimates the TDS from that reading.

Temperature Sensor:

The definition of a temperature sensor is essentially an electronic device used to take accurate temperature measurement readings.

Water Level Detector:

Level sensors are used to detect the level of substances that can flow. Such substances include liquids, slurries, granular materials, and powders. Level measurements can be done inside containers or it can be the level of a river or lake.

Gas Sensor:

Gas Sensor: A gas sensor is a device that detects the presence of different gases in the air and provides an indication of their concentration levels. It is commonly used in various industries to monitor and control air quality, safety, and environmental conditions.

Moisture Sensor:

A moisture sensor is a device that measures the amount of moisture present in a substance or environment. It is commonly used in agriculture, construction, and other industries to ensure proper moisture levels for optimal results.

Motion Sensor:

A motion sensor is a device that detects movement in a specific area and can trigger an action, such as turning on lights or activating an alarm.

LDR Sensor:

An LDR sensor, or Light-Dependent Resistor sensor, detects and measures the amount of light in a particular environment. It works by changing its resistance in response to the amount of light present and can be used in a variety of applications such as automatic lighting systems and optical communication devices.

Servo Motor:

A servo motor is a type of motor that is commonly used in robotics and automation. It is designed to accurately control the position, velocity, and acceleration of a mechanical system. This is achieved through a closed-loop control system that uses feedback from sensors to adjust the motor's output. Servo motors are widely used in applications such as CNC machines, 3D printers, and robotic arms.

Dc Motor:

A DC motor is a type of electric motor that converts direct current electrical energy into mechanical energy through the interaction between a magnetic field and current-carrying conductors.

This is called Pie chart. The “pie chart” is also known as a “circle chart”, dividing the circular statistical graphic into sectors or sections to illustrate the numerical problems. Each sector denotes a proportionate part of the whole. To find out the composition of something, Pie-chart works the best at that time.

This is called Switch. The switch is mounted atop the dashboard and controls the activation of a function. The switch widget is great for simply turning something ON or OFF. Can be linked with a Boolean variable. An example of how it is used in a sketch:

This is called Timer. The timer is mounted atop the dashboard and controls the action to be fired. One can pick a start & end date for when the variable should be triggered, and for how long it should be active. This variable can be controlled in real time using a graphical widget that you can place on the dashboard.

A bar chart is a way of summarizing a set of categorical data. The bar chart displays data using a number of bars, each representing a particular category. The height of each bar is proportional to a specific aggregation ; for example the sum of the values in the category it represents.

An area chart is a graph that combines a line chart and a bar chart to show changes in quantities over time. It’s similar to a line graph in that data points are plotted and connected by line segments. It is used to track real time data, as well as tracking historical data.
