In this IoT project, I have shown how to make The smartest home automation system with FAN Speed Control using ESP32 and the new Blynk IoT platform, sensor, and IR remote control relay. You can also control appliances, and fan speed without internet from IR remote and manual switches. PCBA from $0 (Free Setup, Free Stencil) Download the PCB Gerber file for ESP32 IoT Projects For this ESP32 project, I have used the FREE plan of the Blynk IoT platform and the ESP32 can save the last GPIO state in NVS flash memory (EEPROM). During this Internet of things tutorial video, I have covered the following topics: 00:13 Control ceiling Fan Speed with Blynk & IR Remote. 00:31 Control relays with Blynk, IR Remote & Manual Switch. 01:24 Required Components for ESP32 control fan dimmer. 02:16 Circuit of the ESP32 IoT-based home automation system. 03:38 Connection of 4-step fan regulator with ESP32 control relay. 07:06 Set up Blynk IoT cloud for ESP32 IoT project. 08:55 Source Code for the ESP32 IoT project with fan dimmer. 10:23 How does the ESP32 control the Fan Speed. 13:09 Set up Blynk IoT app Mobile Dashboard. 14:03 Controlling relays & fan with Blynk app, IR remote, & switches. Required Components for this ESP32 home automation system 1. ESP32 DEV KIT V1 2. 8-channel 5V SPDT Relay Module 3. TSOP1838 IR receiver (with metallic casing) 4. DHT11 temperature sensor 5. Switches or pushbuttons 6. 4-step Fan regulator OR ( & 250V Capacitor, 1/2W Resistors, 220k 1/4W Resistors, and 4-step selector switch) Amazon India Affiliate links: ESP32 DEV KIT V1: 8-channel 5V Relay Module: Amazon United States Affiliate links: ESP32 DEV KIT V1: 8-channel 5V Relay Module: Help my projects on Patreon: Feel free to donate any amount: Download the Code for the ESP32 Blynk IoT project from the following article. Previous Videos: Last Blynk ESP32 Project: Get the HEX codes from IR remote: Steps to program ESP32 with Arduino IDE: Important Links: New Blynk IoT Cloud: IFTTT sign up: Important points: 1. In the 4-step regulator step-2 & 3 must be internally connected. 2. IR receiver sensor must have a metallic casing. Otherwise, you may face issues while trying to get the Hex code. 3. ESP32 can save the last GPIO state after power failure. 4. You can control fan speed relays with switches & IR remote if WiFi is not available. 5. Install the correct version of the ESP32 board and libraries as mentioned in the code. 7. Please watch the complete video, otherwise you may face some issues. **Please take proper safety precautions while working with high voltages. During the Blynk tutorial video, I explained all the steps to connect the fan dimmer circuit with ESP32 control relays. You can also add Blynk Automations to control the relays and fan speed with DHT11 sensor reading as shown in the previous video. With this ESP32 home automation project, you can control the fan speed and relays without internet from the IR remote and manual switches. ESP32 will automatically connect with the Blynk cloud when the internet comes back and the relays will turn on as per the previous states. You can use any IR remote to control the relays, just get the HEX codes of unused IR remote buttons, and control the appliances with those buttons. This smart relay module PCB can be used for different ESP32 projects which I will cover in upcoming videos. #homeautomation #iotprojects #esp32 #fandimmer ----------- Thanks For Watching... ✅ SUBSCRIBE ✅LIKE ✅SHARE ✅ COMMENTS Find out more projects: Facebook: Instagram: Telegram: ----------- ----------- WARNING: This video is for demonstration and educational purposes only.
