Overview: IoT based Visitor Counter
Today in this project, will make IoT Based Bidirectional Visitor Counter using NodeMCU ESP8266 & Blynk IoT cloud. This project is useful for monitoring the total number of visitors entering, exiting, and current visitors available from any part of the world using the Blynk IoT cloud platform. Infrared or IR Sensors are used to count the total number of incoming and outcoming visitors. The Visitors’ data is uploaded automatically to Blynk cloud using the NodeMCU ESP8266 Wi-Fi Module.
You can use this ESP8266 NodeMCU based IoT Bidirectional Visitor counter in the hall, shopping mall, office entrance gate to count the total number of visitors. This device counts the total number of visitors entering through the gate & also counts the total number of visitors exiting through the different gates. Basically, it calculates the total number of current visitors by subtracting the outgoing visitor from the incoming visitor. When a single person enters the room, the light turns on automatically. Whenever there are no visitors present in the room, the light turns off automatically.
Previously, we have made the Visitor Counter Project using Arduino & OLED Display. But this time we will send the data to the Blynk cloud instead of simply watching it on OLED Display.
Components Required
We can make this IoT Bidirectional Visitor Counter using ESP8266 Wi-Fi Module, a pair of IR Sensor, SSD1306 OLED Display, and a Relay Module.

Started to have a play with a #ESP8266 in the form of a #Wemos D1 Mini. What I like about this form factor is you can just power it from the micro USB port, it has a USB to TTL convertor built in and you can also get mini "shields" for it. I have setup a #DS18B20 temperature sensor and the wemos wakes up from sleep every 10 mins, connects to the WiFi and sends the temperature to a cloud data system called #thingspeak. #iot

First of all, let’s talk about the app part. Here I have added two tabs. Usually, one for Live Monitoring. Each time user swipes a card a message is received. And another tab is used for remote access control.
All the users are turned off
As you can see in the above image all the buttons are turned on. which means admin has given access to all the three users. If the buttons are turned off then users won't be able to open the door lock.

MakePython ESP32 is a powerful, generic Wifi+ BLE MCU module target to MicroPython learners & developers. It is true “breadboard compatible”, with the very detailed pins explanation, it is easy to learn& use. The MakePython ESP32 has 2 optional for users: WROOM(NO PSRAM) and WROVER(8MB PSRAM).
Overview: ESP32 MAX30100 WebServer
In this project, you will learn to make ESP32 based MAX30100 Pulse Oximeter Webserver. Our previous project was based on ESP8266 NodeMCU where we monitor the BPM and Sp02 parameters of the oximeter sensors in the webserver. But in today’s project, we will monitor Heart Rate and oxygen saturation (Sp02) values on the ESP32 Webserver. You can monitor those values from any smartphone or PC which has wifi support and browsing capabilities.
In today’s tutorial, you will learn to:
- Interface the MAX30100 Pulse Oximeter sensor with ESP32.
- Program ESP32 board using Arduino IDE.
- Create a beautiful ESP32 local webserver to display BPM and Sp02 parameters.
Components Required
To make an ESP32 based MAX30100 Pulse Oximeter Webserver, you will need the ESP32 Development board. A MAX30100 Pulse oximeter sensor, few jumper cables, and a breadboard. You can buy all these components from the Amazon link provided below.
Interfacing MAX30100 with ESP8266 NodeMCU
The Circuit assembly for MAX30100 Pulse Oximeter Webserver using ESP32 is very simple. The MAX30100 Oximeter Sensor works with the I2C bus. So, Interface the I2C pins (SCL &SDA) oximeter modules with GPIO 22 and GPIO 22 pins of ESP32. Connect the INT pin to the NodeMCU GPIO 19 pin. Similarly, provide 3.3V power to the VCC and Ground the GND pin. Basically, you can follow the circuit diagram to make your connections.

Finished this #minecraft ore light for Artie, the panels are printed separately and glued together. Semi transparent filament was used to allow the light through. An addressable LED strip was used with a #ESP8266 based controller running #WLED software which allows you to create preset colour patterns, which we can change with a button. Also used a battery shield for the #Lolin controllerto make it portable. Not sure how long the battery will last. ift.tt/w4MlfVA ift.tt/pVh8LsO kno.wled.ge/ #electronics #maker #3Dprinting
