ESP32 Power Supply PCB board, ESPRESSIF ESP32 Devkit WROOM, ESP32 WROOM 32D
This is this the 2nd most highly recommend tutorial for beginners and project makers. While performing the basic experiments you can use your laptop to power up the ESP32 module and you can make temporary connections using a Breadboard. After you are done with all the testing and you are satisfied with your programming, finally, a time comes when you realize that it seems quite impractical to power up the ESP32 Module using a Laptop and moreover you cannot use a Breadboard for the final connections. So this article is all about how to make your own Regulated Power Supply board for the ESP32 module. This Power supply board can also be used as the development board. As you can see I have added the male and female type headers due to which you can easily interface the ESP32 module with different types of sensors and other electronic devices. I have also added some extra holes where you can directly solder Sensors, wires from other electronic devices, and so on.

TDS Sensor and ESP32 IoT based Water Quality Monitoring system, IoT TDS sensor, ESP32 TDS Sensor
In today’s episode you will learn how to make IoT based Water Quality Monitoring System using TDS Sensor, DS18B20 water proof one wire digital temperature sensor, 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’s 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 purer the water, the lower the conductivity. To give a real-life example, distilled water is almost an insulator, but salt water is a very efficient electrical conductor.

Firebase Android Application Designing using Android Studio, Firebase Android Tutorial, ESP32 DHT11
This is part 2 of my previous tutorial #6 based on the ESP32 and Firebase. In which I explained how to set up your firebase database account for the ESP32 Wifi + Bluetooth module so that the Sensor data can be monitored in real-time from anywhere around the world. I highly recommend first watch this tutorial and then you can resume from here. Because, in this tutorial, I will be using the same Firebase Database account.
In this tutorial, which is version 2, you will learn how to design your own Firebase Android application using Android Studio. For the demonstration purposes, I have connected the DHT11 Temperature and Humidity Module with the ESP32 WiFi + Bluetooth Module. The Temperature and Humidity values from the ESP32 are sent to the Firebase Android application.

ESP32 IoT Power Relay, IoT Relay
IoT Power Relay Project using ESP32 Wifi + Bluetooth Module- This DIY IoT Power Relay based on the ESP32 WiFi + Bluetooth module can be used to control the High Power Devices like for example Water Pumps, Air Conditioners, Heaters and other High Ampere loads. The best thing about this IoT Power Relay is that, it can be controlled from two different sources.
The best thing about this IoT Power Relay is that, it can be controlled from anywhere around the world using the WiFi technology. So, it really doesn’t matter how far you are, if you have the internet connection, you can turn ON and Turn OFF the Power Relay.
The Same Power relay can also be controlled over the Bluetooth using the Cell phone application designed in Android Studio. I have a very detailed tutorial on how to design your own android cell phone application using Android Studio.
For the Demonstration purposes I will be controlling a Water Pump using the IoT Power Relay. To control the Water Pump over the WiFi connection all you need is; open your IoT Power Relay cell phone Application and start controlling the Water Pump. This application should be used only if you are far away.
If you are at home or near to the Power Relay then you can use your Bluetooth application to control the Water Pump. This also eliminates the risk of Electric Shock as there is no need to physically operate the switch. The IoT power relay can be used to control the Water Pump without any risk.
Imagine the situation, you are in a Washroom and the Water Tank is empty and you don’t feel like going downstairs, then all you need is open your cell phone application and turn ON the water pump using the IoT Power Relay. If you are out of the Bluetooth range then you can use the other application that works with the WiFi. Isn’t it amazing? No physical contact with the High voltage switches, quite safe, and reliable.
In this tutorial we will cover,
- Technical specifications of the Power Relay
- Power Relay Driver circuit designing and calculation
- Complete Circuit Diagram explanation
- IoT Power Relay Blynk Application designing
- ESP32 Programming, and finally

ESP32 and ESP8266 Together on the same IoT Platform ThingSpeak
ESP8266 and ESP32 Together on the same IoT Platform ThingSpeak- I have been using Nodemcu ESP8266 and ESP32 modules for quite a long time with different IoT platforms including the Blynk, Ubidots, Google Firebase and Thingspeak.
While using the Blynk application you are limited to use only one type of the module, you can select the ESP8266 or you can select the ESP32 Dev Board from the device list as you can see in the image given above. With Blynk application you can use multiple devices but of the same type.
There is an article, in which I explained how to use multiple Nodemcu modules with the same Blynk application. This project can really help you in designing advanced level projects where you need to monitor multiple devices installed at different locations.
So, if you plan to use the same IoT supported devices then go ahead use blynk. But if you plan to use different modules, then you will need to switch to another IoT Platform Ubidots or ThingSpeak.
In this tutorial, you will learn how to use the Nodemcu ESP8266 and ESP32 Wifi + Bluetooth module with the ThingSpeak IoT platform. A potentiometer is connected with the Nodemcu ESP8266 WiFi Module. The sensors data from the ESP32 and ESP8266 modules are displayed on the charts in ThingSpeak IoT platform.

ESP32 with GSM
I have been using GSM and ESP32 Wifi + Bluetooth Modules for quite a long time in different types of Arduino based and IOT related projects. In my previous tutorial, I used the same GSM SIM900A module with the Nodemcu ESP8266 Wifi Module; I will provide a link in the description, if you want to watch this tutorial. In this episode, you will learn how to use EPS32 Wifi + Bluetooth Module with GSM Sim900A module. ESP32 and GSM module together can be used in different advanced level projects.
The main advantage of using the ESP32 with the GSM Module is that, if you have the internet connection and the ESP32 module is connected with the Wifi, then you can monitor the sensor data in real time from anywhere around the world using the Blynk application or any other IOT Platform and you will also be able to receive the alert messages via GSM network.
There are situations when the internet is not available, in a situation like this you won’t be able to monitor the data in real time, but you will get the alert messages via GSM network each time the sensor crosses a threshold value.
For the demonstration purposes I have connected a variable resistor with the ESP32. You can use any type of analog and digital sensors.
In this tutorial, we will cover;
- Complete circuit diagram explanation.
- Blynk application designing
- Code explanation and finally
