I. Product Introduction

The WE-HJ-M7 portable weather station is a high-precision, low-power agricultural and forestry environmental monitoring device designed for convenient field use. It supports wireless transmission, requires no debugging, and can be quickly deployed, making it suitable for various emergency short-term meteorological observations, mobile weather monitoring, and other meteorological data acquisition tasks. Equipped with high-precision ultrasonic sensors, it accurately measures meteorological elements such as wind direction, wind speed, atmospheric pressure, temperature, and humidity simultaneously. The monitored data is transmitted wirelessly to the IoT cloud platform, providing users with accurate meteorological data to support scientific decision-making and prevention measures.

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