1、 Product Introduction

1. The large screen LCD displays soil moisture, soil temperature, soil salinity, soil in-situ pH, air temperature and humidity, dew point value, and rainfall;
2. Large capacity data storage, internal Flash can store up to 30000 monitoring data (optional 4G card for storage);
3. Universal USB communication interface, convenient for data download; Data can be viewed on the host or imported into the computer for curve chart viewing, analysis of maximum, minimum, and average values, and can also be exported as an Excel spreadsheet for backup viewing;
4. After an unexpected power outage, the data saved on the host will not be lost;
5. Dual use of AC and DC, equipped with a large capacity lithium battery for fast charging, economical and environmentally friendly, convenient and fast;
6. Equipped with GPS positioning function, it has the ability to automatically collect and real-time display the latitude and longitude coordinates of the location and save them; (Optional)
7. Equipped with Chinese voice alarm function, it can set voice alarm for exceeding values, provide real-time Mandarin voice alarm for exceeding parameters, and directly broadcast real-time environmental parameter values; (Optional)
8. All sensor probes have the consistency function. The interfaces of different soil meteorological sensors can be interchanged. The host can access different sensors through the hub without affecting each other's measurement accuracy. The host can access 32 sensors at the same time. The sensor communication cable can reach 100 meters.
