RS485 4-20MA OUTPUT LORA LORAWAN Soil Water Potential Sensor

Short Description:

The soil water potential sensor can be easily inserted into the soil profile pit and wrapped with wet soil. Measuring and recording is very simple. Maintenance-free and calibration-free, it can measure a wide range of soil water potential; no irrigation is required, and its large range makes it an ideal sensor for measuring water potential in natural systems.We can provide servers and software, and support various wireless modules, GPRS, 4G, WIFI, LORA, LORAWAN.

Product Features

● The automatic calibration device is used to calibrate the sensor one by one, and the accuracy is greatly improved.

● There is no drift caused by degradation of ceramic materials.

● Just bury the sensor, set the clock and measurement interval, you can start to collect data without programming.

● Epoxy resin overlapping injection molding process ensures that it is suitable for long-term field monitoring research.

● Can provide servers and software, can integrate LORA LORAWAN WIFI 4G GPRS, can view data on mobile phones and PCS.

Product use

● First determine the installation depth and position of soil water potential;

● Take a soil sample at the installation position, add water and mud to the soil sample, and fill the soil water potential sensor with mud;

● The sensor covered with mud is buried to the installation position, and the soil can be backfilled.

Product Applications

This product can be widely used in irrigation, drainage, to provide scientific basis for crop growth and dry areas, frozen soil, roadbed and other fields of soil water research.
