Easy Watcher / monitoring device

When we leave home, we don't know whether we have turned off the cooker; when we are outside, we may forget to lock the door but we are not informed of. This is why Easy Watcher is coming. Easy Watcher is a useful system just consisted of two types of sensors and a receiver. The sensors can be set on any places or products need sort of protection, like window, cooker, light switcher, etc. After putting sensors on these areas, we can be noticed whether the status of the objects is changed via the receiver. Moreover, we can use our smartphone to receive the signal from the receiver to know the status of our space when we are outside.
