YF5 Wind Speed Alarm DeviceBasic principle:
The instrument uses a three cup rotating frame wind speed sensor. A cover plate is installed on the rotating shaft of the rotating frame, and a photoelectric switch and cover plate are used to convert the rotational speed of the rotating frame into a pulse frequency signal, which is output to the alarm host. The host shapes the pulse sent by the wind speed sensor and sends it to the input port of the counter/timer of the microcontroller. The host measures the frequency of the wind speed signal every second, and then performs a 3-second sliding average processing on the frequency per second to calculate the 3-second average wind speed. Every second, the measured sliding average wind speed is compared with the wind speed forecast alarm value and alarm value. If the measured value is greater than the forecast alarm value or alarm value, the microcontroller will activate the corresponding forecast alarm relay and alarm relay. Their set of switching contacts can be used to control external devices and also provide sound and light alarm signals.
twoBasic use: YF5 wind speed alarm has a simple structure and high degree of automation. It can continuously monitor instantaneous wind speed and is suitable for departments such as airports, ports, tower cranes, and fire prevention that are very concerned about wind speed to monitor and alarm in real time.
