220V Cooling Fan for the environment and health

Objective "220V Cooling Fan" invention is to save energy, life a lot easier for people. The basic idea: the use of pyroelectric infrared sensor sensing the presence or absence of the human body, automatically controlled fans to start and stop; real-time access indoor temperature according to the temperature sensor module, the function of the current wind speed automatic temperature regulation. In addition, the system through an external keyboard, to retain the traditional fan stall converter, stop, time, and other functions.
Innovation:
1. "220V Cooling Fan" can automatically control on and off;
2. The fans can automatically control the speed according to the temperature of the environment;
3. greatly expanding the ordinary fan of timing;
4. All functions in the form of a liquid crystal display whole, to achieve fool-style man-machine communication platform.
Technology key: Make sure the regulator pyroelectric infrared sensor accurately detects human existence; the temperature can be fed back to ensure proper control "220V Cooling Fan" speed; ensure mutual coordination both the functional modules, but also to work independently.
