If you are having a parkin issue in your locality or apartment you can build this simple IOT based Smart Parking System that uses an IR sensor opens the gate and gives you update over the internet to your phone. A crystal of 11.0592 MHz is connected for generating the clock. Our Embedded Power ICs are automotive qualified. The interface to the 8051 is simple I2C with SDA and SCL pins connected to the any two pins of 8051. This function is used to set the microcontroller to work in slave mode for SPI communication. This sensor can detect an object if the distance in between the object and the sensor is 2 to 10 cm. Then we check to see if the output of the sensor is high or low, if the output of the sensor is high that means no motion is detected, else motion is detected, we also print this status in the serial monitor window. This crystal needs two same value capacitors (33pF) for generating a clock signal of the desired frequency. It is a microcontroller-based control system used to perform a specific task of operation.
