The YGC-GTM tubular multi-layer soil moisture monitor uses the frequency domain reflection method (defined in GB/T28418-2012) to measure the soil moisture in each soil layer based on the frequency changes of the electromagnetic waves emitted by the monitor in materials with different dielectric coefficients. Use high-precision digital temperature sensors to measure the temperature of each soil layer. It can measure the temperature and humidity of 10cm, 20cm, 30cm and 40cm soil layers at the same time, and can also customize other different soil layers according to needs. It is suitable for long-term uninterrupted monitoring of representative soils; it can provide RS485 signal output and can also have built-in 4G wireless The communication module and lithium battery transmit data to the IoT data platform through the GPRS wireless network, and the data can be viewed in real time using computers and mobile phones. It is convenient and fast, and greatly meets the needs of all aspects of use.
The tubular multi-layer soil moisture monitor has many advantages such as being lightweight, easy to install, easy to use, and accurate in measurement. The instrument uses precision sensors and smart chips, and consists of a soil moisture sensor, a soil temperature sensor, a solar power supply and a transmission device.
At present, the products are widely used in environmental information monitoring and collection in agriculture, forestry, environmental protection, water conservancy, meteorology and other industry sectors. They are also used in water-saving irrigation, flower gardening, grassland and pasture, rapid soil testing, plant cultivation, greenhouse control, etc. Precision agriculture and other fields to meet the needs of scientific research, production, teaching and other related work.
