i want to desing a pototype of system for automobile car parking such that when a car is exist at the parking lot in the car park, the sensor will automatic detect and send a signal to microcontroller to desplay the location of this car. below are my question:
1)if i use ultrasonic sensor or infrared sensor, what things should i consider when using them?
2) i am using 16f877a to connect the sensor, do anyone can show me how to connect it (Give me schematic diagram if possible)?
3) Please suggest me cheaper infraed detecter?
