Handheld meteorological instrument

sketch:

The handheld intelligent agricultural meteorological environment detector is a small-scale environmental monitoring station designed specifically for farmland and grassland, which monitors soil, water, and other environmental parameters closely related to vegetation and crop growth. It mainly observes five environmental parameters related to agriculture, including air temperature, air humidity, light intensity, carbon dioxide concentration, dew point temperature, and photosynthetically active radiation, providing good support for agricultural research and production.

Technical parameters:

Air temperature range: -30~70 ℃ Accuracy: ± 0.2 ℃ Resolution: 0.1 ℃

Air humidity range: 0-100% accuracy: ± 3% resolution: 0.1%

Light intensity range: 0-200Klux Accuracy: ± 5% Resolution: 0.1Klux

Carbon dioxide measurement range: 0-5000ppm accuracy: ± 3% resolution: 0.1%

Dew point range: -20~+50 ℃ accuracy ± 0.5 ℃ resolution 0.1 ℃

Photosynthetic effective radiation range: 400-700nm Sensitivity: 10-50 μ v/μ mol · m-2 · s-1

Configurable GPS module, GPRS module, SMS module, MAX485

Outstanding performance:

Adopting an integrated structure design, with built-in GPS module, GPRS module, and external SD card, it can accurately measure the geographic 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 measured point. Upload environmental factor measurement data of the tested point with one click through the built-in GPRS. At the same time, data can be directly exported to the computer through an external SD card. (Optional)

This machine is compact in size, beautiful, easy to operate, reliable in performance, and extremely convenient to carry in the wild. After connecting the sensor to the host, the records can be manually stored or the sampling interval can be set arbitrarily by the host to automatically store the recorded data.

The large Chinese LCD display tracks and records the values, number of groups, and low voltage warnings of various tested environmental factors throughout the process. The host has a built-in large capacity memory that can store 300000 pieces of data and has automatic power-off data storage protection function.

After inserting each sensor into the host, the host has automatic recognition function, good sensor consistency, and can combine sensors according to needs. Sensor interfaces with different parameters can be converted to each other without affecting measurement accuracy.

The instrument has multi-channel automatic detection extension function, which can achieve synchronous detection of multiple sensors simultaneously connected.

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

Scope of application:

Widely used in agriculture, forestry, environmental protection, water conservancy, meteorological industries, dryland water-saving irrigation, geological exploration, plant cultivation and other fields.
