The detection device preferably uses a pulse signal by receiving an electric signal generated by an external object, and as for the electric signal received by the electric equipment, the electric signal is a signal conventionally received by the electric equipment, and the type of the electric signal is not limited, but as for the detection device, a pulse signal is generally used, and if the electric signal is not a pulse signal, the electric signal can be converted into a pulse signal, and for example, a monostable trigger is added between the detection device and the external object.
referring to fig. 1, in the first embodiment, the electrical device 100 is mainly a wireless communication module, and receives an input of an electrical signal of an external object, where the external object is a key 50, that is, the electrical device receives the electrical signal of the key (the electrical signal generated by the key is a pulse signal, which is referred to as a key instruction), and then sends the key instruction to another corresponding device, for example, the electrical device is a remote controller, and the other corresponding device is a television, so that when a user operates the key of the remote controller, the remote controller is woken up, receives the corresponding key instruction, and sends the key instruction to the television, thereby achieving the purpose of remotely controlling the television. Of course, the number of keys may be one or more depending on the powered device or corresponding device requirements.
