Wind direction wind speed sensor, as its name implies, is a tool to measure wind direction wind speed. It converts the flow velocity variable of air into a signal with a certain corresponding output signal, which can be applied to the measurement level of meteorological, military, aviation, seaport, environmental protection, industry, agriculture and forestry departments. The need for wind parameters.
In these fields of application, wind direction and wind speed are very important parameters, and the wind direction anemometer has become a universal measuring tool. The wind direction anemometer contains two sensors, a wind direction sensor and a wind speed sensor. These two sensors can work simultaneously, measuring two parameters of wind direction and wind speed.
The induction component of the wind speed sensor of the wind direction wind speed monitor is a three-cup type wind cup assembly. When the wind speed is higher than 0.4 m/s, the rotation is generated, and the signal conversion circuit is a hall integrated circuit. Under the horizontal wind driven, the wind cup group rotates, and the magnetic rod disk rotates through the main shaft. Dozens of small magnets on the magnetic pole from a plurality of rotating magnetic fields, and the pulse signal is induced by the Hall magnetosensitive element, and the frequency thereof increases with the wind speed. Large and linear increase. Calculation formula: V=0.1F; V: wind speed, unit: m/s; F: pulse frequency, unit: Hz.
The wind sensor of the wind direction wind speed monitor has a single-plate wind vane with an auxiliary target at the opposite end. The angle conversion requires a seven-digit Gray code photoelectric code disk. When the wind vane rotates with the wind, the code wheel rotates through the main shaft. Each rotation of 2.8125, seven sets of illumination and receiving optoelectronic devices located on the upper and lower sides of the code wheel will generate a new set of seven-bit parallel gray code, which will be shaped and inverted. Phase output. The azimuth-angle-Gray code-binary code comparison table is a key basis for wind direction measurement microcontroller programming.
In general, the two sensors of the wind direction wind speed monitor get the characteristics of good dynamic performance, high linear precision, high sensitivity, wide measuring range, good interchangeability and superior wind resistance.
Below we briefly introduce some of the highest performance and technical parameters of the downwind wind speed monitor.
The wind direction anemometer consists of three modes: manual, automatic and computer lock. The three modes can be established by users according to their needs. Data storage is powerful and can store up to 60,000 data. The wind direction anemometer has 32 channels of simultaneous detection, enabling multi-point synchronized detection.

Two prohibitions:
1. It is forbidden to use a wind speed sensor in flammable gas environment.
2. It is prohibited to place the wind speed sensor probe in flammable gas.
Seven don’t:
1. Do not disassemble or modify the wind speed sensor;
2. Do not expose the probe and the anemometer body to the rain;
3. Do not touch the internal sensor part of the probe;
4. Do not place the anemometer in a place with high temperature, high humidity, dust and direct sunlight;
5. Do not wipe the wind speed sensor with a volatile liquid.
6. Do not drop or press the wind speed sensor;
7. Stay away from the sensor part of the probe while the anemometer is energized.

Three MUST: Be sure to use the wind speed sensor correctly according to the requirements of the instruction manual; in use, if the wind speed sensor emits an abnormal smell, sound or smoke, or if liquid flows into the anemometer, be sure to turn off the battery immediately; the wind speed sensor is long-term. Always remove the internal battery when not in use.
1. The wind direction sensor is removed from the package and assembled. The point of attention is: the wind mark rod is inserted in the direction of the arrow; the front and rear weights of the wind direction indicator should be adjusted, and the front and rear wings should be in the same plane as the rotation axis; the north pole and the north line should be In the same direction.
2. The sensor component is composed of a wind speed sensor, a wind direction sensor and a sensor bracket. When assembling, the sensors should be connected to the respective inserts, then sat on the bracket sleeve, and tighten the screws.
3. The working voltage of the sensor is usually 5 VDC. Owing to the built-in lightning protection device, the actual working voltage should not exceed 6 volts.
