I. Overview
Appropriate soil temperature and humidity are important environmental conditions for crop growth. They not only directly affect the growth and development of crop roots and the activity of soil microorganisms, but also affect the movement of water in the soil. Therefore, in order to ensure that soil temperature and humidity can promote crop growth, people need to collect and process soil temperature and humidity to maintain it within a certain range.
The QTS-7 Soil Temperature and Humidity Recorder is a new type of environmental detection instrument launched by our company based on market demand. The instrument can collect real-time data by connecting corresponding sensors externally, and can output data and generate reports using computer management software. The instrument can also collect the specific longitude and latitude positions of each designated point through a GPS receiver. The recorder can automatically store the soil moisture values, temperature values, longitude and latitude position values of each designated point measured, and can also be transmitted to a computer through an RS-232 serial port for storage and processing.
Product composition: Soil temperature and humidity sensor, data collector, soil temperature and humidity tester, communication system, power supply device, etc.
Application areas: It can be applied to soil moisture monitoring, water-saving irrigation, greenhouse control, precision agriculture and other fields.

2、 Product Features
1. The QTS-7 soil temperature and humidity recorder adopts an integrated structure, which combines the data collector, sensors, and portable suitcase into one chassis, making it extremely convenient to carry in the field. The outer chassis is molded with plastic grease material molds, which are beautiful, sturdy, and easy to install. It can be hung anywhere for testing.
2. The portable waterproof and shockproof structure is windproof, rainproof, shockproof, corrosion-resistant, and resistant to strong magnetic interference. It does not require manual intervention during operation and is suitable for use in the wild and harsh weather environments.
3. The recorder is equipped with a large LCD display screen, which has the function of displaying Chinese characters and graphics. It can display multiple data channels on one screen and view real-time monitoring data and various setting parameters.
4. The instrument host adopts a high-performance microprocessor as the main control CPU and a large capacity data storage, which can continuously store 30000 pieces of data. And the storage time can be set.
5. The instrument is equipped with professional soil analysis software, which can store and download stored data in EXCEL standard format into a microcomputer, and can also generate various soil analysis charts.
6. The system adopts a low-power design, and after one charge, the internal battery can work continuously for more than 15 days.
7. For the convenience of setting up sensors to measure depth and soil sampling, the system is equipped with a soil drill.
