IoT TDS Sensor for Water Quality Monitoring using ESP32

top projects

In this tutorial, you will learn how to make IoT based Water Quality Monitoring System using TDS SensorDS18B20, and ESP32 Wifi + Bluetooth Module by the ESPRESSIF systems. As this project is based on the IoT “Internet of Things” based technology, so, the EC “Electrical Conductivity” and Temperature can be monitored from anywhere around the world using the Blynk application.

EC or Electrical Conductivity of water is its ability to conduct an electric current. Salts or other chemicals that dissolve in water can break down into positively and negatively charged ions. These free ions in the water conduct electricity, so the water electrical conductivity depends on the concentration of ions. Salinity and total dissolved solids (TDS) are used to calculate the EC of water, which helps to indicate the water’s purity. The pure the water, the lower the conductivity. To give a real-life example, distilled water is almost an insulator, but saltwater is a very efficient electrical conductor.

IoT earthquake monitoring network

top projects

Real-Time Earthquake Detector Sensor Network is an advanced level research project which basically aims to develop a WIFI based Real-time Earthquake Detector Sensor Network which can be used at the Province level, Country-level or even at the Global level. With the help of this project, the earthquake detection system can be installed in every city which will make a complete network, and every earthquake detector monitoring device can be monitored in real-time using the IoT platform.

Due to the real-time monitoring, we can easily predict in which direction the earthquake waves are traveling, this way the people can be informed in time before the earthquake hits that area. Each earthquake sensor data will have the date and time information as well. The uniqueness of my research project is that it can be practically adopted. So that’s why I also made a Prototype model so that I can clearly explain my whole research work. During the practical installation, I will only consider two locations, Peshawar and Nowshera; later you can increase the number of locations to be monitored. I have also designed some high-quality PCBs for this which can be used to power up the Nodemcu ESP8266 WiFi Modules and the Vibration sensors.

Firebase with ESP32 for Sensor Monitoring

top projects

ESP32 Firebase- Before I am going to explain how to use the ESP32 with Firebase, first, I am going to talk about some of my previous projects based on the Google Firebase. In my last tutorial on the Google Firebase Database, I explained how to send a sensor value from the Nodemcu ESP8266 Wifi Module to the Google Firebase Database. If you want to use Nodemcu ESP8266 WiFi Module with the Google Firebase then read my article “Nodemcu Firebase Database Tutorial“, this is a beginners level project and explains the very basics like for example, how to setup your own Google Firebase account, How to connect an analog sensor with the Nodemcu ESP8266, and send the sensor data to the Firebase Database.

I also uploaded an advanced version based on the Nodemcu ESP8266 and Firebase Database. The advanced version is about the students’ attendance system using GSM sim900A module, RFID MFRC522, 16×2 LCD, and the Google’s Firebase Database. This is really an amazing project, you will learn a lot of new things like for example, how to use an RFID module, GSM Module, and how to send attendance data from the Arduino to the Google Firebase Database. But before you are going to make the advanced version first I recommend read my getting started tutorial on the Nodemcu Firebase Database.

In today’s tutorial, we will be using the ESP32 Wifi + Bluetooth Module by the Espressif Systems with the Google Firebase database. This is the same company that created the ESP8266 series of chips, modules, and development boards. Unlike the Nodemcu ESP8266 Wifi Module, the ESP32 Wifi + Bluetooth module is becoming very famous as it consist of more analog pins; while in Nodemcu ESP8266 there is only one Analog pin A0.
