Industrial volumetric water content MODBUS-RTU RS485 UART 2-5V 3 in 1 Soil Moisture & Temperature & EC Sensor for farm
The new developed soil moisture temperature EC three-in-one sensor is a soil sensor developed with a new technical scheme, whichcan measure soil moisture, temperature and conductivity at the same time, and carry out compensation calculation among parameters,eliminating the influence of conductivity on water, temperature on water and temperature on conductivity, can perform compensation operation and accurate evaluation.
This product can be used to measure the moisture content of saline-alkali land, which is not affected by the salt content of soil and can accurately measure the moisture content of soil.
It adopts imported epoxy resin, high quality stainless steel, more resistance to acid and alkali corrosion, steel needleParameters of the category | Moisture | EC (Conductivity) | Temperature |
