An electronic module for enhancing an operation of a conventional parking meter. The electronic module comprises a shell defining a hollow conformation and being attachable to a conventional parking meter, in substitution to an upper housing portion of that conventional parking meter. The electronic module has a meter condition sensor for detecting from a distant point one of the time expiry indicator and the violative condition indicator of that parking meter, when the indicator is in an indicating mode, and a vehicle sensor affixed to the shell for detecting from a distant point, a parked vehicle. The electronic module further has: an electronic circuitry mounted inside the shell and having a power source for operating the module; means for receiving a first signal from the meter condition sensor and a second signal from the vehicle sensor; means for processing the first and second signals and means for transmitting a coded message to a remote receiver. Each side of the shell has a light operable into an ON mode by the electronic circuitry simultaneously to a transmission of the coded message. There is also provided on a front face of the shell, an electronic display screen for displaying an advertisement message to a user of this parking meter, and on a top portion thereof, a solar panel to recharge the battery of the electronic circuitry.
