Meteorological data logger is equipped with green energy power management module systems, such as the use of solar powered systems approach can ensure the continuous rainy days the situation ten days off without steady work. 6, the use of stainless steel light metal stents and field protective box, appearance, corrosion resistance, anti-jamming, long-term operation in harsh outdoor environments, including 2.5m height mounting bracket can be mounted meteorological sensors according to the specification requirements. 7, perfect lightning, interference and other protective measures. In electronic circuits using a lightning suppress noise and other anti-jamming measures, in terms of hardware and software design uses a derating design, electromagnetic compatibility design, excluding outliers and other reliability design technology, reliable operation in a variety of harsh field environments, low power consumption, high stability, high accuracy, can be unattended. Third, the primary and secondary school weather station technical indicators: Technical parameters Measuring range Resolution Accuracy Unit Ambient temperature -50 ~ 150 0.1 ± 0.1 ℃ Relative Humidity 0 ~ 100 1 ± 2% RH dew point of -40 ~ 50 0.1 ± 0.2 ℃ wind 0 ~ 75 0.1 ± (0.3 + 0.03V) m / s wind direction 0 ~ 360 2.5 ± 5 ° precipitation 0 ~ 999.9 0.1 ± 0.2 mm atmospheric pressure 450 ~ 1100 0.1 ± 0.3 hpa evaporation 0 ~ 100 0.1 ± 1.5% mm UV radiation 0 ~ 1000 1 ≤5% w / m2 sunshine 0 ~ 24 0.1 ± 0.1 h soil temperature -50 ~ 150 0.1 ± 0.2 ℃ soil humidity 0 ~ 100 0.1 ± 2% carbon dioxide 0 ~ 2000 1 ± 20 ppm noise 20 ~ 130 0.1 ± 5 dB wind chill index of -79 ~ + 54 1 ± 1 ℃ heat index of 28 ~ 80 1 ± 1 ℃ UV Index 0 ~ 16 0.1 ≤5% index 220V AC power systems on-site weather station power supply to ensure normal operation of the user according to scene selection mode power supply 5V DC 12V dc wind hybrid power system solar power systems RS232 communication cable communication distance 0 ~ 20m users to choose the way RS485 communication cable communication distance 0 ~ 1000m wireless microwave radio communication distance 0 ~ 1000m GPRS mobile wireless communications under field conditions Distance Any distance limited meteorological observations SMS communications stand 2.5 meters removable bracket suitable for temporary observation use, easy to carry. 3.5 m mounting bracket suitable for roof installation or venue restricted area 10 meters using standard bracket for the National Weather installation of lightning protection systems for the protection of on-site weather station lightning users to choose according to the scene mode power supply lightning arrester standard meteorological observation field signal mine dew point temperature: water vapor content of the air remains constant, if the water temperature is reduced due to cooling and air temperature reaches saturation, namely the dew point temperature. Dew point temperature can also be used to indicate how much water vapor content, the dew point temperature is higher, it means more water vapor content of the air. Heat Index: Heat Index for the real temperature of the human body at a high temperature and humid environment feel. When the body is in a high temperature environment, the body will automatically adjust the body can achieve more comfortable temperature, which is a mechanism for cooling the body sweating in the sweat evaporation process consumes energy, so the aim is to promote sweating evaporation, and then consume our body heat. Makes us feel cool. When the temperature is high and low humidity, the body is discharged to evaporate sweat quickly; contrast, at high temperature and humidity are high, the person's back to slow down the evaporation rate of sweat a lot, when the temperature due to the humidity long-term rise or human sweat can not evaporate in the case, then there will be cramps, heat exhaustion or heat stroke happen. The index can only be used as a reference, this is different because of the different degree of adaptation of human heat. Changes in the situation of human heat index 32.6 ℃ ~ 40.4 ℃ extra careful - there may be cramps and heat exhaustion 40.7 ℃ ~ 54.2 ℃ dangerous - human failure may occur 56.5 ℃ ~ 78.2 ℃ very dangerous - at any time heatstroke wind chill index: cold and wind weather big time, the heat generated from the body will quickly taken away by the wind, feel the temperature of the human body and therefore lower than the actual temperature. This feeling is the wind chill temperature index. Wind chill index will be affected by temperature and wind speed, wind chill index case is low, should avoid prolonged exposure to the outdoors, so as to avoid excessive loss of body heat and cause danger. UV Index: UV Index is a measure of the degree of influence of solar ultraviolet radiation in the Earth's surface of human skin. UVI UV Index trace level 0-2 3-4 5-6 orders of magnitude lower middleweight 7-9 excess risk of grade level 10 to 15 primary and secondary schools Stations Origin: China
