WE-HJ-A7 Agricultural and Forestry Environmental Weather Station

I. Product Introduction

The Agricultural and Forestry Environmental Weather Station is a high-precision, low-power consumption meteorological monitoring device designed for field use in agricultural and forestry environments, complying with the GB/T 24689.1-2009 standard (Plant Protection Machinery - Agricultural and Forestry Microclimate Information Collection System). The equipment consists of meteorological sensors, data transmission units, power supply systems, communication modules, IoT cloud platforms, and other components. It can automatically monitor local meteorological elements such as air temperature and humidity, atmospheric pressure, wind speed, wind direction, rainfall, and light intensity. The monitored data is transmitted wirelessly via the data transmission unit to the IoT cloud platform, providing accurate meteorological data for agricultural and forestry production. This helps users make scientific decisions and implement preventive measures, thereby improving the efficiency and safety of agricultural and forestry production.

It is widely used in fields such as meteorology, agriculture, forestry, environmental protection, oceanography, airports, ports, scientific research, and campus education.
