Abstract
A parking information sensing device is disclosed. Each parking space in a parking lot is disposed with a parking information sensing device, detecting whether a car on the parking space. By means of a driving control circuit, the sensing device drives a light emitting unit to emit a light and a reflecting element of the parking space is on a pathway of the light. Light is reflected by the reflecting element and then passes light sensing unit that detects the reflected light and generates a first sensing signal sent to the driving control circuit. Thus the driving control circuit judges if there is no vehicle on the parking space. On the other hand, it judges if there is a car on the parking space according to another sensing signal. The sensing device further includes a first transmitting/receiving unit that forms a wireless mesh network among parking information sensing devices.
