1. Field of the Invention
This present invention relates to a sensing apparatus and a sensing system, and particularly relates to the sensing apparatus and the sensing system having the sensing apparatus employing character/string signal.
2. Description of the Prior Art
The modern lives demand more security than ever in various environments, e.g. household, educational institution, factory, office building, etc. A sensing apparatus is usually implemented in those environments to detect the smoke or gas for alerting the public people or security guards. The conventional sensing devices are typically stand-alone machines that can not communicate with other electronic equipments. Along with development of communication technology, some sensors communicating with host machine via wireless transmission protocol (e.g., IEEE 802.15.4) are developed recently. However, due to higher cost of the sensing apparatus with capability of wireless transmission protocol, those sensing apparatus do not gain popularity in the market in a desired speed.
In accordance with one aspect of the invention, a sensing apparatus including a sensing device, a wireless signal transmitting device and a character/string signal generating device is provided. The character/string signal generating device is electrically connected to the sensing device and the wireless signal transmitting device. The character/string signal generating device functions to respond actuation of the sensing device for generating a character signal or a string signal. The wireless signal transmitting device transmits the character signal or the string signal by a wireless transmission protocol. The character signal or the string signal represents the abnormal status of environment or actuation state of monitored environment.
