Water Quality Monitoring System

Ensure safe and clean water with our monitoring system.

ABOUT PROJECT

Drinking Water Quality Monitoring System with ESP32 WiFi Module, TDS/EC Sensor & Temperature Sensor. This complete system can be used to monitor the drinking water quality, i.e Water Electrical Conductivity or EC & Water Temperature. The EC & temperature value can be monitored online from any part of the world on an IoT Server called Thingspeak.

This project uses a TDS Sensor and DS18B20 waterproof temperature sensor along with ESP32 WiFi Module to measure water quality monitoring parameters like Electrical Conductivity & temperature. The EC & Temperature value will be displayed on a 0.96″ I2C OLED Display.

Water Quality Monitoring System Circuit

Components Used

Analog TDS Sensor

The Analog TDS Sensor is an Arduino-compatible TDS sensor/Meter Kit for measuring TDS value of the water. It can be applied to domestic water, hydroponic and other fields of water quality testing. This product supports 3.3 ~ 5.5V wide voltage input, and 0 ~ 2.3V analog voltage output, which makes it compatible with 5V or 3.3V control systems or boards.

Temperature Sensor

This is a pre-wired and waterproofed version of the DS18B20 Sensor used to measure something far away, or in wet conditions. The Sensor can measure the temperature between -55 to 125°C (-67°F to +257°F). The cable is jacketed in PVC. These 1-wire digital temperature sensors are fairly precise, i.e ±0.5°C over much of the range

ESP32 WiFi Module

The ESP32 is a series of low-cost and low-power System on a Chip (SoC) microcontrollers developed by Espressif that include Wi-Fi and Bluetooth wireless capabilities and dual-core processor. If you’re familiar with the ESP8266, the ESP32 is its successor, loaded with lots of new features.

OLED Display

OLED, which stands for Organic Light Emitting Diode, is a relatively new type of display for televisions, smartphones, and computer monitors.
