Portable meteorological instrument

Brief description:

The portable meteorological instrument is specially designed for the local small-scale environment of farmland and grassland. It is a farmland microclimate station that monitors environmental parameters such as soil, water vapor, etc. that are closely related to the growth of vegetation and crops. It mainly observes 12 environmental parameters and meteorological elements related to agriculture, including air temperature, air humidity, light intensity, carbon dioxide concentration, dew point temperature, photosynthetically active radiation, soil temperature, soil moisture, soil salinity, soil pH, wind speed, and wind direction.

Configurable GPS module, GPRS module, SMS module, MAX485

Outstanding performance:

It adopts an integrated structural design, built-in GPS module, GPRS module, and external SD card, which can accurately measure the geographical information of the measured location. In addition to displaying the measured environmental parameters and stored data, the interface can also display the latitude and longitude of the measuring point. The built-in GPRS can upload the environmental factor measurement data of the measured point with one click. At the same time, the data can be directly exported to the computer through the external SD card. (Optional)

This machine is small and beautiful, easy to operate, reliable in performance, and extremely convenient to carry in the field. After the host is connected to the sensor, the records can be stored manually or the sampling interval can be set arbitrarily through the host to automatically store the recorded data.

The large-screen Chinese LCD display tracks and records the values, groups, and low voltage alarms of each measured environmental factor throughout the process. The host has a built-in large-capacity memory that can store 300,000 data and has a power-off data automatic storage protection function.

After each sensor is inserted into the host, the host has an automatic recognition function, the sensor consistency is good, and the sensors can be combined according to needs. The sensor interfaces of different parameters can be converted to each other, which has no effect on the measurement accuracy.

The instrument has a multi-channel automatic detection expansion function, which can realize synchronous detection of multiple sensors connected at the same time.

The central station software is powerful. Data is uniformly collected, processed and analyzed through the central station software. The recorded data can be exported to the computer through the USB interface at any time, and can be stored as an EXCE table file to generate data curves for further data processing by other analysis software. It has the function of setting the coloring of the over-limit area, and the color change warning of over-limit data can be used as a basis for environmental evaluation.

Scope of application:

It is widely used in agriculture, forestry, environmental protection, water conservancy, meteorological industry, dryland water-saving irrigation, geological exploration, plant cultivation and other fields.
