HCT-4 Catheter Type Soil Moisture Monitor for agriculture

The tubular soil monitor developed by our company is an intelligent device meticulously designed for the precise monitoring of soil moisture.

Leveraging advanced sensing technology, stable data transmission solutions, and a long-lasting power supply design, it effectively meets soil monitoring needs across diverse environments-such as farmlands, orchards, greenhouses, and woodlands-providing reliable data support for agricultural production, vegetation cultivation, and environmental research.

The monitor transmits data to an IoT platform via 4G wireless networks, allowing users to view information in real-time on computers and mobile phones; this convenient and efficient approach fully satisfies a wide range of operational requirements.

Environmental Monitoring Sensors

Features

●The product design is flexible and can measure soil temperature and humidity at any depth between 10-80cm (usually 10cm layer). The default is 4-layer, 5-layer, and 8-layer standard tubes. Support customization.

●It is composed of sensing, collection, transmission and power supply parts, with integrated design and easy installation.

● It has domestic version and international version data transmission scheme, which is convenient for users outside the mainland. (For international version, please inform the sales staff in advance)

●The collector configuration software uses the WeChat applet to connect to the mobile phone through Bluetooth. The device can be controlled on any Android or Apple mobile phone equipped with the WeChat APP, realizing in-depth interaction, configuration and remote sending between the mobile APP and the device. (Some functions are currently open to users)

●The sensor has a built-in high-efficiency lithium battery, and the RTU adopts a low-power consumption design. When fully charged, it can work for more than 180 days in continuous rainy days.

●Adopting a magnetic switch design, the magnet that comes with the machine can be used to control the collector on and off. Prevent the site from being accidentally shut down in the wild.

●Using cloud platform storage technology, the data sent each time can be saved to an independent cloud platform or a third-party platform that meets the "Hydrological Monitoring Data Communication Protocol SL651-2014". It supports MQTT service docking with third-party platforms and supports protocol customization. Default API interface docking.

● Other functions: power display, network positioning.

●Extensible elements: GPS positioning, more accurate positioning; parameter expansion such as air temperature, humidity, air pressure, dew point temperature, and body temperature.

●Extensible functions: Open the user's quadratic calibration function (function of cubic term + quadratic term + linear term + constant) to provide more accurate data for professional scientific researchers. Users can provide data, and our company assists in calculating the coefficients of the function.
