Handheld environmental monitoring device introduction
HLY-HQX03 is a farmland microclimate station specially designed for the local small-scale environment of farmland and grassland to monitor the soil, moisture and other environmental parameters closely related to vegetation and crop growth. It mainly observes the environmental parameters and meteorological elements related to agriculture, such as air temperature, air humidity, light intensity, carbon dioxide concentration, photosynthetic effective radiation, wind speed and wind direction, so as to provide good support for agricultural scientific research and agricultural production.
 
Handheld environmental monitoring device features
1. HLY-HQX03 adopts integrated structure design, with built-in GPS module, GPRS module and external SD card, which can accurately measure the geographic information of the measured location. The interface can not only display the measured environmental parameters and stored data, but also display the longitude and latitude of the measured point. Upload the environmental factor measurement data of the measured point through the built-in GPRS. At the same time, the data can also be directly exported to the computer through the external SD card. (optional)
2. This machine has the advantages of small volume, beautiful appearance, simple and convenient operation, reliable performance and convenient carrying in the field. After the host is connected to the sensor, the record can be stored manually, or the sampling interval can be set arbitrarily by the host to automatically store the recorded data.
3. The large screen Chinese liquid crystal display can track and record the value, group number and low-voltage alarm of each measured environmental factor in the whole process. The host has built-in large-capacity memory, which can store 300000 pieces of data, and has the function of automatic storage and protection of power-off data.
4. After each sensor is inserted into the host, the host has automatic identification function and good sensor consistency. The sensors can be combined according to the demand. The sensor interfaces of different parameters can be converted to each other, which has no impact on the measurement accuracy.
5. The instrument has multi-channel automatic detection expansion function, which can realize the synchronous detection of multiple sensors connected at the same time.
6. The central station software has powerful functions. The data is collected, processed and analyzed uniformly through the central station software. The data in the record can be exported to the computer through USB interface at any time, and can be stored as Excel form file to generate data curve for further data processing by other analysis software. It has the function of coloring the out of limit area and the color change warning of the out of limit data, which can be used as a basis for environmental assessment.
