Hebei Longyuntong LYA-DG Conduit Soil Monitor

The catheter-type moisture monitor uses the FDR principle to measure the humidity of each soil layer based on the frequency changes of the electromagnetic waves emitted by the monitor in materials with different dielectric coefficients. It uses high-precision digital temperature sensors to measure the temperature of each soil layer. By default,it measures the temperature and humidity of 10cm,20cm,30cm,and 40cm soil layers at the same time. It is suitable for long-term uninterrupted monitoring of representative soils. It can have built-in RTU and battery,and can provide RS485 output,LoRa wireless transmission,and GPRS wireless network. Transfer data to the Internet of Things data platform and view the data in real time using computers and mobile phones. It is convenient and fast,and greatly meets the needs of all aspects of use.

This soil temperature and humidity 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.

Features of catheter-type moisture monitor

(1) 32-bit MCU has faster computing speed and higher accuracy.

(2) Tubular integrated structure supports layered measurement,making multi-layer data acquisition more convenient.

(3) The number and depth of sensors can be selected according to project requirements.

(4) Integrated tubular design: Batteries,sensors,motherboards,communication modules and other components are all designed in the same tube. Each sensor is designed with an integrated tubular structure. The sensor is a fully enclosed multi-depth sensing unit with higher integration. high.

(5) The profile is not damaged during installation,and the damage to the soil is small,making it easier to protect the on-site environment.

(6) No need for calibration,no need for on-site calibration,and no need for lifelong maintenance.

(7) Field installation can be completed in 15 minutes,equipped with a switch button to start and stop at will.

(8) It has the characteristics of low power consumption,small size,easy to carry and move,and simple installation,operation and maintenance.
