The DO300 parking lock is designed for parking space sharing control and can be remotely controlled automatically for locking and unlocking.

 Furthermore, the occupancy status of the parking space can be detected, and when the vehicle leaves, it can be automatically locked.

 Automatically unlock when the reserved vehicle comes to near the parking space (this function requires platform support). 

With the built-in wireless communication module (NB-IoT, 4G LTE, GPRS and etc), the shared parking lock can interact with cloud applications. The device can be widely used in smart city projects.
