Ever wondered how easy it could be if your parking lot would keep track of the information about when a car entered and exited, and if the parking lot is still empty to occupy more cars?? We'll then its time for you to get your hands dirty, because this tutorial will cover all about it.
With the help of the thingsai.io online IoT platform we'll design a smart parking lot which keeps track of all these details and with its online visualization tools things would look so easy and sophisticated.
We'll be designing the system using IR Sensors and interface it to the esp8266 nodemcu development board through the GPIO Pins.
Hardware Pictures:NodeMCU is a LUA-based interactive firmware for Espressif ESP8622 Wi-Fi SoC, as well as an open source hardware board that contrary to the $3 ESP8266 Wi-Fi modules includes a CP2102 TTL to USB chip for programming and debugging, is breadboard-friendly, and can simply be powered via its micro USB port.
Power: 5V via micro USB port
The pinout for the esp8266 nodemcu board is displayed below:
Here's to link to understand how IR Sensors work:
