Summary of the Circuit

This circuit integrates a variety of sensors with an ESP32 Wroom microcontroller to measure environmental parameters such as turbidity, temperature, and pH levels. Additionally, a TCS3200 color sensor is included for detecting color intensity. The ESP32 Wroom serves as the central processing unit, interfacing with each sensor and potentially providing a means for data communication and processing.

Component List

Turbidity Module

• Pins: VCC, GND, OUT
• Description: This module is used to measure the turbidity (cloudiness) of a liquid, indicating the degree to which the water loses its transparency due to the presence of suspended particulates.

Temperature Sensor

• Pins: Temp GND Black, Temp VDD Red, Temp DQ Data Yellow
• Description: A sensor for measuring temperature. It typically provides a digital output corresponding to the temperature it measures.

PH Meter

• Pins: Signal, VCC, GND
• Description: This sensor is used to measure the pH level of a solution, indicating its acidity or alkalinity.

ESP32 Wroom

• Pins: Multiple GPIOs, 3V3, 5V, GND, etc.
• Description: A powerful microcontroller with Wi-Fi and Bluetooth capabilities, suitable for a wide range of applications, including interfacing with various sensors.

TCS3200 Color Sensor

• Pins: GND, OUT, S0, S1, S2, S3, VCC, LED
• Description: This sensor can detect the color of a surface and is often used in color sorting applications.
