Abstract: An environmental data monitoring and feedback controlling system and a method thereof are disclosed, a first wireless transceiver module is electrically connected to environmental sensors to form a sensor module, a server is electrically connected to a second wireless transceiver module to form a network gateway, and the server polls the sensor module to receive and store the environmental data through the network gateway, and permits a display panel device to load and display the stored environmental data in a chart. When the environmental data exceeds a preset threshold, a warning device is driven to write the received environmental data into a register of a programmable logic controller of an air conditioning device, so that the control logic automatically controls the air conditioning device to activate or stop based on the environmental data stored in the register, thereby improving the correction immediacy for environmental abnormality.

Abstract: A test device and method using a separate control module for test are disclosed, where a main console is replaced with a control module of the test device, the control module may generate a control command after receiving the a command transmitted from the main console, and transmit the control command to at least one PLD corresponding thereto, the PLD may control the GIPO comprised thereby to test the unit under test according to the received control command, whereby reducing the test time and achieving in the effect where the main console may do the other work concurrently when engaging in the test for the unit under test.
