IoT Visitor Counter and Automatic Light Control using ESP32 Ultrasonic Sensor and Blynk

Today in this project, will make IoT Based Bidirectional Visitor Counter using an Ultrasonic sensor, ESP32 & Blynk IoT cloud. This project is useful for monitoring the total number of people entering, exiting, and the current number of persons inside the room from any part of the world and using the Blynk IoT cloud platform.

It also controls the AC home appliances like Light bulbs, AC, fan, cooler, etc. Automatically. A pair of Ultrasonic HC-SR04 Sensors are used to count the total number of incoming visitors and outcoming visitors. The Visitors’ data is uploaded automatically to the Blynk IoT cloud using the ESP32 microcontroller.

How to use the new blynk iot app with this project? there's no blynk legacy now.

[sulymanjamiu]

I have done this kind of project, everything has worked at first test-run on the breadboard. Unfortunately, it is not working again after I disconnected it from PC and I have trying to fix it but it is still the same thing.
The code will just upload and all other components will not work as expected, it is only the red light on relay that it on. I will be glad if you can help me with it 😢

[pratikadhikari]

How much total it will cost to make this device ? Can we make multiple upto 100 device that can be controlled through the same ui?

[hidayahappiness]

Sir can you please provide the link of the blynk app...

[on_the_earth]

hi sir,
Can i have the back picture of this pcb which is used in video.
actually i am doing work on this project so please help me.

[on_the_earth]

can we use ESP8266 in place of ESP32.
please reply ASAP.

L.c.d. display are use for this project it's possible
