The wind speed sensor leads out a wire about3Meter lead Black lines with white stripes are positive Black is negative In the application of single chip microcomputer circuit Black line access GND The white stripe is used as voltage sampling and connected to the corresponding MCU AD mouth AD The port does not need to make any pull-down or pull-up resistance If you like One in parallel104Porcelain capacitor is enough。
This device belongs to DIY product fit DIY Application occasions or occasions where accuracy requirements or grading requirements are not strong For example, it is used to measure a certain wind speed threshold It is not suitable for professional meteorological measurement or other important occasions。
- The wind speed sensor is designed to prevent rain. It uses three hemispherical bowls with a diameter of 6CM and is installed in a 120-degree branch. Under the action of wind, it can rotate. The greater the wind speed, the faster the rotation.
- When the wind rotating component rotates, the diameter is about 22CM, which drives a small DC generator to generate DC voltage. The higher the wind speed, the higher the DC voltage generated. The maximum DC voltage can be 2V. Please refer to the following for specific wind speed and voltage output parameters. In the attached manual, the error of this parameter is about 10%. If it is used in important occasions, please take it carefully.
- The base can be fixed where needed with 3 6MM screws.
- The wind speed sensor leads out a lead of about 3 meters, black with white stripes is positive, and black is negative. When the single-chip circuit is used, the black wire is connected to GND, and the white striped wire is used as a voltage sample to be connected to the corresponding AD port of the single-chip computer. The AD port does not need any pull-down or pull-up resistors, just connect a 104 ceramic capacitor in parallel.
- This device is a DIY product, suitable for DIY applications or occasions where accuracy or classification requirements are not strong, such as measuring a certain wind speed threshold, and not suitable for professional meteorological measurement or other important occasions.
