![]() ![]() ![]() Never use 5 volts of the Arduino to power the Nodemcu esp8266 wifi module. As you can see from the pic above, all the pins are clearly labeled. Nodemcu ESP8266 wifi unit, we can track the parking slots from anywhere in the world from this module. In IR there are two black and white LEDs, one for tx and the other for RX. What I’m going to explain in the diagram. While the OUT pin is connected to the IO pins of Arduino. The field is connected to the ground of Arduino. The 5 volt pin of Arduino is attached to the Vcc. As you can see, the VCC, GND, and OUT are clearly labelled with the three male headers. I use this IR detector for car detection. I would appreciate your support in this way! About the IR sensor Module: I may make a commission if you buy the components through these links. These sensors are mounted to the Arduino.So when a car is parked in the slot, the infrared sensor is triggered and the command is sent to the wifi module nodemcu esp8226, Nodemcu sends the command to the Blynk request. ![]() The presence of the car in the slot is detected by each infrared sensor. The parking space is split into two parking spaces.Įach parking space is equipped with 3 slots and each slot has one detector. In this task, in the Blynk program, we will also learn how to use the tabs and led widgets. The parking slots can be tracked from anywhere in the world using the Nodemcu esp8266 wifi module and Blynk software. IOT based Car Parking-In this tutorial, you will learn how to use the Arduino, Nodemcu esp8266 wifi module and Blynk software to build an IOT-based Car Parking Slots monitoring system.
