ABSTRACT:
A security apparatus is used in a kitchen or a bathroom for detecting the gas leakage and controlling the water temperature and water level in a bathtub or a container. This apparatus is capable of detecting the gas leakage and monitoring the water temperature and level in a container or a bathtub via three relays. The security apparatus further provides an emergency lamp circuit for illumination and a radio circuit for user(s) to listen to a radio program when the users are in a kitchen or a bathroom. The radio program may be replaced with an alarm when a gas leakage occurs, water temperature is too hot or the container or the bathtub is full.
