Wireless Agricultural Weather Monitoring Station Multi-Element Weather Station

I. Product Introduction

The ZD-HJ-A7 Agricultural and Forestry Environmental Weather Station is a high-precision, low-power consumption environmental monitoring device designed for field use in agriculture and forestry, compliant with the GB/T 24689.6-2009 standard (Plant Protection Machinery—Agricultural and Forestry Microclimate Information Acquisition System). The system consists of meteorological sensors, a data acquisition host, a power supply system, a communication module, and an IoT cloud platform. It automatically monitors local meteorological elements such as air temperature and humidity, atmospheric pressure, wind speed, wind direction, rainfall, and light intensity, transmitting the collected data wirelessly to the IoT cloud platform. This provides accurate meteorological data for agricultural and forestry production, assisting users in making scientific decisions and implementing preventive measures to enhance productivity and safety.

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