Aiming at the situation that with the increasing number of vehicles dramatically

parking is becoming more and more difficult

and it often takes a long time when the spare parking space is unknown

a geomagnetic lock parking management system based on magnetoresistance effect is proposed

which can acquire parking space information in real-time. The system uses magnetoresistive sensors to detect the current status of the parking space

and uploads the information to the nodes in the parking area through NRF24L01 wireless transmission

this node collects the information of parking spaces in this area. Once the status of parking spaces changes

it will upload the information to the server using WiFi. The server gets the information of each parking space and process the data. The owner can get parking information through the client-end and choose the nearest parking space.
