I. Product Overview

The ZD-HJ-A16 Agriculture and Forestry Environmental Weather Station is a high-precision, low-power, field-deployable real-time monitoring device designed for agricultural and forestry environmental observation. It complies with the GB/T 24689.6-2009 standard (Plant Protection Machinery—Agroforestry Microclimate Information Acquisition System). The system consists of meteorological sensors, a data acquisition unit, power supply system, communication module, LED display screen, and 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. Captured images and data are transmitted wirelessly to the IoT cloud platform, providing accurate meteorological and growth condition information for agricultural and forestry production. This supports scientific decision-making, pest control, and improves efficiency and safety in agricultural and forestry operations.

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