I. Product Introduction

The ZD-HJ-A6 Agricultural and Forestry Environmental Weather Station is a high-precision, low-power consumption device designed for field monitoring in agricultural and forestry environments. It complies with the GB/T 24689.6-2009 standard (Plant Protection Machinery—Agricultural and Forestry Microclimate Information Acquisition System). The equipment 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. The collected data is transmitted wirelessly to the IoT cloud platform, providing accurate meteorological data for agricultural and forestry production. This assists users in making scientific decisions and implementing preventive measures, thereby improving the efficiency and safety of agricultural and forestry operations.

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