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. 1 x Weather Sensor Item Type: Weather Environment SensorMaterial: ABSWeight: Approx. 710.00g / 25.04ozOutlet: Aviation Socket, Sensor Cable Length: Approx. 3m/ 9.8ftGuard Grade: IP65Power Consumption: 200mWOutput Signal: RS485 SignalWorking Environment Humidity:0~100 Percent RHOperating Temperature: -40℃~+70℃Size: Approx. 151x100mm / 5.94x 3.94in  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: 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.
