I. Product Introduction

The ZD-HJ-I7 Intelligent Greenhouse Weather Station is a device used to monitor and record meteorological conditions inside greenhouses or sheds. The equipment consists of meteorological sensors, a data acquisition host, a power supply system, a communication module, an IoT cloud platform, and other components. It can automatically monitor meteorological elements such as indoor air temperature and humidity, soil temperature and humidity, soil pH, soil salinity, carbon dioxide, and more. The monitored data is transmitted wirelessly to the IoT cloud platform, providing users with accurate meteorological data inside the greenhouse, helping users better manage the greenhouse or shed environment and improve production efficiency.
