Abstract
The design and assembly of a smart device constituent of a micro-machined (a.k.a. MEMS, Micro Electro Mechanical Systems) mass flow sensor and an electrically controllable valve for applications in safety enhancement and intermit connectivity for residential or commercial gas range is disclosed in the present invention. The said smart device detects the gas flow at the unattended situations and sends information to the destined mobile devices of the users via the network such that it enables the users to remotely execute actions of either shutting off the gas supply or call for relevant party's immediate attention. The said smart device shall also automatically shut off the gas supply should the transmitted signal to users failed to send feedback signal such that it can prevent the safety incidents due to leakage or overheating or even fires. The capability of the MEMS mass flow sensor shall also provide the thermal value measurement of the supplied gases and enable the user to program the gas range for making complete tasks of cooking substances in the unattended situation.
