Handheld meteorological instrument

Overview:

The handheld meteorological instrument is designed specifically for small-scale environments in farmland and grasslands, and is a farmland microclimate station that monitors environmental parameters such as soil and water vapor closely related to vegetation and crop growth. It mainly observes four environmental parameters and meteorological elements related to agriculture, including air temperature, air humidity, light intensity, and carbon dioxide concentration, providing good support for agricultural research and production.

Technical parameters:

Air temperature range: -30~70 ℃ Accuracy: ± 0.2 ℃ Resolution: 0.01 ℃

Air humidity range: 0~100% Accuracy: ± 3% Resolution: 0.1%

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

Carbon dioxide measurement range: 0-2000ppm Accuracy: ± 3% Resolution: 0.1%

Configurable GPS module, GPRS module, SMS module, MAX485

Outstanding performance:

Adopting an integrated structural design, with built-in GPS module, GPRS module, and external SD card, it can accurately measure the geographic information of the measured location. The interface not only displays the measured environmental parameters and stored data, but also displays the longitude and latitude of the measurement point. Upload environmental factor measurement data of the measured point with one click through the built-in GPRS. At the same time, data can also be directly exported to a computer through an external SD card. (Optional)

This machine is compact, aesthetically pleasing, easy to operate, reliable in performance, and extremely convenient to carry in the wild. After connecting the sensor to the host, records can be manually stored or automatically stored by setting sampling intervals on the host.

Large screen Chinese LCD display, tracking and recording the values, number of groups, and low voltage alarms of various tested environmental factors throughout the process. The host is equipped with a large capacity memory, which can store 300000 pieces of data and has automatic storage protection function for power outage data.

After each sensor is inserted into the host, the host has an 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 a multi-channel automatic detection extension function, which can achieve synchronous detection of multiple sensors connected simultaneously.

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 a USB interface, and can be stored as an Excel spreadsheet file to generate data curves for further data processing by other analysis software. It has the function of setting color for exceeding limit areas and providing color warning for exceeding limit data, which can serve as a basis for environmental evaluation.

Applicable scope:

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