Handheld Agricultural Weather Station: Your Field Companion

Handheld Agricultural Weather Stations are customized monitoring devices for small-scale environments such as agricultural fields and pastures, focusing on monitoring soil and climate conditions that are critical to crop growth. The device accurately measures key weather parameters such as air temperature, humidity, light intensity, carbon dioxide concentration, dew point temperature and photosynthetically active radiation, providing powerful data to support agricultural research and production.

The device has a wide measurement range and high accuracy readings, such as air temperature covering -30 to 70 degrees Celsius with an accuracy of ±0.2 degrees Celsius; air humidity measurement range of 0 to 100% with an accuracy of ±3%; light intensity of 0 to 200 Klux with an accuracy of ±5%; carbon dioxide concentration of 0 to 5000 ppm with an accuracy of ±3%; dew point temperature of -20 to +50 degrees Celsius with an accuracy of ±0.5 degrees Celsius; photosynthetically active radiation (PAR) of -20 to +50 degrees Celsius with an accuracy of ±0.5 degrees Celsius; photosynthetic activity radiation (SAPR) of 0 to 5 degrees Celsius. 0.5 degree Celsius; photosynthetically active radiation 400 to 700nm, sensitivity 10 to 50μv/μmol-m^-2-s^-1.

The device can also be equipped with optional GPS, GPRS module and SMS module, as well as MAX485 interface to enhance its functionality.

The design of the device focuses on integration and portability, with built-in GPS and GPRS modules, support for SD card data storage, and the ability to display measurement data and latitude/longitude information of measurement points. Users can upload data with one key through the GPRS module or export data to PC through SD card. Its large Chinese LCD display not only provides full data tracking, but also has data storage, low voltage alarm and automatic storage protection function, which can store up to 300,000 data.

The device supports automatic identification of sensors to ensure the consistency of sensors and measurement accuracy, as well as multi-channel auto-detection expansion function, allowing multiple sensors to be detected synchronously. The software of the central station is comprehensive, capable of collecting, processing and analyzing data in a unified way, supporting data export and curve generation, providing a basis for environmental assessment.
