Feature: 1. Multifunction: Weather environment sensor has five in one function, wind speed, wind direction, temperature, humidity, aerair pressure. The low power consumption of the whole machine is only 0.2W, which is especially suitable for scenes with high power consumption requirements. 2. Modular Design: Professional weather environment meter's compact size, modular design, easy to integrate and flexible layout. Suitable for grid deployment. 3. Efficient Filtering Algorithm: Weather environment sensor adopts efficient filtering algorithm and special compensation technology for rainy and foggy weather, so as to ensure the stability and consistency of data. 4. Superior Performance: Wide adaptability to the environment, after strict high and low temperature, waterproof, anti salt spray and other environmental testing, probe in the case of non heating, in the ‑40 ℃ low temperature environment, the equipment is still able to work normally. 5. Applicable Fields: This kind of instrument is commonly used in agricultural meteorology, intelligent street light, scenic environment monitoring, highway meteorology, environment monitoring, aerospace and other fields, in order to understand the situation of the wind and make corresponding countermeasures. Specification: Item Type: Weather Environment Sensor Material: ABS Weight: Approx. 710.00g / 25.04oz Outlet: Aviation Socket, Sensor Cable Length: Approx. 3m/9.8ft Guard Grade: IP65 Operating Voltage: DC9V-30V Power Consumption: 200mW Output Signal: RS485 Signal Working Environment Humidity:0~100 Percent RH Operating Temperature: -40℃~+70℃ Size: Approx. 151x100mm / 5.94x3.94in Environmental Elements Range Degree of Accuracy Resolution Power Consumption Wind Speed 0-45m/s Start Wind Speed≤0.8m/s 0.01m/s 0.12W ±(0.5+0.02V)m/s Wind Direction 0-360 ±3° 1° Atmospheric Temperature -40-80℃ ±0.3℃ 0.1℃ 1mW Atmospheric Humidity 0-100 Percent RH ±5%RH 0.1%RH Atmospheric Pressure 300-1100hPa ±0.5 hPa(25℃) 0.1 hPa 0.1mW Electronic Compass 0-360 ±5° 1° 10mW Widely used in: garden, greenhouse, environmental guard, weather stand, ships, wharf, aquaculture, advertising gates, meteorology, marine, environment, airports, harbors, laboratories, industry, agriculture and transportation and other environments of wind direction measurement. Wiring schematic: 485 signal output, the bottom of the sensor has a 4-pole aviation plug, its pin corresponding to the pin definition is as follows: 1. Power positive VCC (Red) 2. Power negative GND (Green) 3. 485A+ (Black) 4. 485B- (Yellow) Note: Make sure the wiring is correct before powering on. Troubleshooting : 1. The meter display value is not correct when for RS485 is output. The meter may not be able to acquire data correctly due to wiring problem or telecommunication serial port failure. Please check whether the wiring is correct and firm, whether the serial port is occupied, and whether the serial port is set correctly; 2. If it is not the above reasons, please contact service.. Package List: 1 x Weather Sensor Note: 1. Please check whether the package is intact, and check whether the product model is consistent with the selection;2. Do not wire with electricity, check the wiring is complete before energizing;3. Sensors are fine devices, users should not disassemble, poignant objects or erosive liquids in contact with the sensor surface to avoid damage to the product;4. Installation environment to ensure that the sensor is not interfered with by other equipment in operation, these devices may not fully comply with common standards, such as radio radar transmission devices, ship engines, engines, etc.;5. Do not install on the same plane as any radar scanning device, at least a distance of 2 meters should be maintained;6. Avoid flocculation from surrounding buildings, e.g. trees, utility poles, tall buildings, etc., which can have an effect on the accuracy of the product;7. The magnetic north pole indicated by the north arrow and the geographic north pole are not exactly the same, therefore, the deviation of the location must be taken into account when calibrating the sensor (error).8. Errors are location dependent and may exceed a maximum of 15 degree (e.g. northeast). In the East China region the error is negligible (<3 degree) Other more detailed information on this section can be found on the Internet. The wind sensor is a fine instrument, so it should be handled gently and not bumped.9. Manual measurement please allow some error.
