weather and instruments

1.Introduction to weather and instruments products

weather and instruments measures temperature, pressure, rainfall, wind direction, wind speed and humidity, integrating thermometer, barometer, rain gauge, wind vane, anemometer and hygrometer.NQ14 weather and instruments is a highly integrated, low-power, quick-to-install, high-precision meteorological observation equipment that is easy to use for field monitoring.

The equipment consists of five parts: meteorological sensor, collector, solar power supply system, pole bracket, and cloud platform.It requires no debugging and can be deployed quickly.It is widely used in meteorology, agriculture, forestry, scientific investigation and other fields.
