Introduction WJ-3E type wind speed indicator is used to measure the wind speed and direction of the special meteorological equipment. The wind speed and direction sensor is installed in the outdoor observation point, and the display terminal is installed in the monitoring room. The sensor can choose the wireless way to return the real-time weather data to the display terminal in the monitoring room for the user observation. In addition, the sensor can use solar power system, so, without laying any cable. The wireless transmitter of this scheme adopts Zigbee technology, Zigbee is a communication technology which is developed for the wireless transmission of industrial field data. It has the characteristics of low power consumption, high reliability and strong anti-interference ability. It should be pointed out that the frequency of 2.4G used by Zigbee is the open frequency of our country. Wind speed sensor and wireless transmitter installed with outdoor, the power supply is a solar cell, the system of solar cell capacity of 12V20AH, the total power consumption of the sensor and wireless transmitter is 1W, the battery is full, in the absence of any sun sustainable work for 7 days or so. Technical Parameter The wind speed Measuring range: 0 ~ 60.0 m/s Accuracy of measurement: plus or minus 2% Start wind speed: < 0.1 m/s Resolution: 12 The direction of the wind Measuring range: 0 ~ 359.9 ° Accuracy of measurement: plus or minus 2% Resolution: 12 Input voltage: DC12 ~ 24V Output signal: 4 ~ 20mA Signal format: 4 ~ 20mA current 0 to 60.0m/s and the wind direction from 0 to 359.9 degrees. Working temperature: -40 ~ 80 Working humidity: 0 ~ 100% De icing heating: no support Material: stainless steel Weight: sensor 1.5kg, triangular base 1.5kg
