Wind speed and wind direction sensor with high sensitivity

Abstract

The invention discloses a wind speed and wind direction sensor with high sensitivity, and the sensor comprises a substrate (1), an insulator (2), a first bottom anode (3) and a second bottom anode (4) which are respectively arranged on the surface of the insulator (2) and are away from each other for a certain distance, a support anchor area (5) which is connected with the insulator (2), an elastic film (8) which is connected with the support anchor area (5), a rigid thin plate (9) which is connected with the elastic film (8), and a wind lever (10) which is arranged on the rigid thin plate (9); the wind lever (10) is arranged in the center of the rigid thin plate (9); the first bottom anode (3) and the second bottom anode (4) are arranged symmetrically relative to the center of the rigid thin plate (7); and the wind direction sensor also comprises a first sharp end emitter (6) and a second sharp end emitter (7) which are arranged on the lower end of the rigid thin plate (9) and are respectively arranged opposite to the first bottom anode (3) and the second bottom anode (4). The wind speed and wind direction sensor with high sensitivity has the characteristics of high detection sensitivity, low power consumption, small size, small temperature drift and the like.

Description

technical field [0001] The invention relates to a structure of a high-sensitivity wind speed sensor, in particular to a structure of a small wind speed sensor which adopts detection tip emission current to realize wind speed measurement. Background technique [0002] Wind speed and direction sensors are widely used in environmental monitoring and field operations. This type of sensor generally consists of a traditional wind cup and vane structure, a pure solid-state hot wire or hot film structure, and an ultrasonic wind speed measurement system. Traditional wind cups and wind vanes have large structures, generally tens of centimeters or more, and there are rotating parts that are easy to wear; although thermal wind speed sensors can be made very small, temperature drift and power consumption are inherent problems. Improvement: The ultrasonic wind speed sensor has been greatly developed in recent years. The sensor has many outstanding advantages such as high precision, large...

Problems solved by technology

Traditional wind cups and wind vanes have large structures, generally tens of centimeters or more, and there are rotating parts that are easy to wear; although thermal wind speed sensors can be made very small, temperature drift and power consumption are inherent problems. Improvement; the ultrasonic wind speed sensor has been greatly developed in recent years. The sensor has many outstanding advantages such as high precision, large measurement range, and long service life.

The downside is the larger size (over 10 cm) and the higher price
