I. Product Introduction

The WE-HJ-I7 Intelligent Greenhouse Weather Station is a device used for monitoring and recording meteorological conditions inside greenhouses or sheds. This device 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 shed. This helps users better manage greenhouse or shed environments and improve production efficiency.
