The portable ultrasonic weather station (touchscreen version) is a lightweight, integrated meteorological system that combines an internal power supply (lithium battery pack), data acquisition, touchscreen display, data storage, data analysis, and data uploading (via 4G communication). It is designed for convenient environmental and meteorological measurements during field operations.
The device measures basic meteorological parameters including wind speed, wind direction, air temperature, air humidity, and atmospheric pressure. Measurement parameters are customizable and can be expanded according to customer requirements.
The system supports both solar panel and 24V DC power supply, which can not only power the device but also charge the built-in lithium battery pack.
This product is widely used in agricultural irrigation, environmental monitoring, field scientific research, transportation, and other applications.
