“…Intelligent awning automatic control system gives priority to automatic control mode, so it can be controlled by light, wind and rain, which of them are monitored through the external sensors, and then the motion of the awning can be automatically controlled according to the signals collected by the sensors mentioned above. AD conversion is used in light control to transform voltage signals, which collected by light sensor, into recognizable binary code and then compare with the setting threshold to judge whether it is day, night or cloudy to take different control operations [9]. Wind speed sensor based on the photoelectric switch is a device, which can produce high and low voltage pulses, and the controller will count these pulses produced per second and compare them with the setting threshold to determine the wind speed.…”

This paper developed an automatic control system for folding arm awning based on environmental factors, which can overcome the disadvantages of the traditional awning of unitary control mode and low level of intelligence. The system consists of sensor unit, controller, drive motor and transmission mechanism. The sensor unit is used for testing light intensity, wind speed and rain, then an AT89S52 SCM single-chip microcomputer which is the core of the controller is applied to receive testing signal and send instructions to AC motor to realize the extending and withdrawing state of the awning according to the corresponding control logic. Meanwhile, this system is able to switch from automatic control to manual control so as to deal with power outage and other special situation and maintain operation of awning. The results of the prototype test show that this system is running steadily and can adjust the working condition of the awning in time according to the environment change. Compared with the current electric awning, the intelligent folding arm awning controlled according to environmental factors can achieve more energy conservation and environmental protection.

“…Since the plate reduces the effect of the ambient light by its shadow, the received light can make the obvious pulse on the output of the photo transistor as (2). The received pulse reaches the amp whose bias eliminated by the DC cut condenser as (3). Finally, the microcontroller gets the waveform gained by the amp exceeding the V TH as (4).…”

“…Instead of using the multiple different sensors, we have proposed the method that same light sensors with similar circuits detect the three events on the window in order to reduce the development cost by volume discount and installation cost (3) . The three events are that the window is opened / closed, the window is shocked, and the key is locked / unlocked.…”

When a thief tries to enter an empty home, the window in general is targeted. To prevent such situations, we have proposed the method that same light sensors with similar circuits detect the three events on the window. However, any real device has never been developed. Also, it has been assumed that the light sensors normally are turned on without consideration of the power consumption. This paper shows the modified detecting methods to meet the capability of the low-end microcontroller and to make the power consumption efficient by intermittent action. Then we demonstrate the practical execution by using a prototype real hardware.
