Home Automation using ESP32 Blynk 2.0 with IR remote control relay temperature sensor | IoT 2021

In this IoT project, I have shown how to make home automation using ESP32 Blynk 2.0 with IR remote control relay, temperature sensor, LDR to control 8 appliances with real-time feedback. You can also control appliances without internet from IR remote and manual switches. $2 for 1-4 Layer PCBs, Get SMT Coupons: https://jlcpcb.com/RHS Download PCB Gerber file for the ESP32 IoT based home automation project https://drive.google.com/uc?export=do... For this ESP32 project, I have used the FREE plan of the Blynk IoT platform. Visit the following website to get electronics components, modules at a very reasonable price https://utsource.net?source=YouTube During the Blynk tutorial video, I have covered the following topics: 00:49 ESP32 control relay with the New Blynk IoT app. 01:51 Controlling Blynk ESP32 with no Wi-Fi. 02:42 Required Components for this Blynk ESP32 IoT project. 03:02 Circuit of the ESP32 Home Automation projects. 04:56 How to set up NEW Blynk 2.0 template for ESP32. 08:10 Set up Blynk cloud Web Dashboard for ESP32. 09:42 How to set up the mobile dashboard in NEW Blynk IoT App. 11:56 Program ESP32 with Arduino IDE. 15:02 Connect ESP32 with Blynk IoT cloud. 16:00 Connect appliances with relay module circuit. 16:04 Controlling appliances from Blynk App, IR remote, and 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. Switches 5. DHT11 temperature sensor 6.

Otherwise, you may face issues while trying to get the Hex code. 2. After compiling the code, you have to press and hold the BOOT button of ESP32 until the code starts uploading. 3. Install the correct version of the ESP32 board and libraries as mentioned in the code. 4. You can use any IR remote for this ESP32 project. 5. Use a stable 5V 5A DC power supply for this smart home project. 6. Please take proper safety precautions while working with high voltage. -----------Related Previous Video Links:------------ Steps to program ESP32 with Arduino IDE    • Programming NodeMCU ESP8266 & ESP32 w...   Get IR Remote Hex Code for the ESP32 control relay    • Smart Home with Amazon Alexa using ES...   ----------Codes---------- Download Code for this Blynk ESP32 IR Remote control relays from the following article https://iotcircuithub.com/home-automa... During the Blynk home automation tutorial video, I have explained all the steps to make this IoT-based smart home system, how to program the ESP32 with the new Blynk Edgent library. In this ESP32 project, you can control the relays without internet from the IR remote and manual switches. ESP32 will automatically reconnect with the Blynk server when the internet comes back. 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 can be used for different internet of things projects which I will cover in upcoming videos. #homeautomation #esp32 #blynk ------------------------------------------------------- Thanks For Watching... ✅ SUBSCRIBE ✅LIKE ✅SHARE ✅ COMMENTS Find out more such IoT projects: https://iotcircuithub.com/ Facebook:   / techstudycell   Instagram:   / techstudycell   Telegram: https://t.me/techstudycell/ Twitter:   / techstudycell   ------------------------------------------------------- Other useful ESP32 home automation projects: Latest ESP32 projects playlist:    • ESP32 Projects   Latest NodeMCU projects playlist:    • NodeMCU Projects   Smart Home using Arduino IoT Cloud ESP32 Alexa control relay with IR remote    • Arduino IoT Cloud ESP32 Home Automati...
