At present, the domestic and foreign research of Throttle Motor Position Sensor network nodes low-power hardware platform design and topology control, network protocol, location technology. To detect the light intensity of the sensor, for example, to achieve a wireless sensor network, according to the sensor to detect the light intensity to turn off or turn on the light. In the wireless sensor network, the common node sends the collected data to the network coordinator. The network coordinator sends the data frame containing the control variable to the node with the indicator light. It can also transmit the light intensity data through the serial port To the computer. Through the installation of the background software on the computer, you can see the light intensity signal changes. By shading the light intensity sensor can change the collected light intensity data, when the light intensity is low, the curve down, and vice versa. This sensor network combines the embedded technology, sensor technology, short-range wireless communication technology, has a wide range of applications. The system does not need to change the structure of the site, do not need any previous fixed network support, can quickly layout, easy to adjust, and has good maintainability and scalability.
