OEM Zigbee FDR RS485 Modbus RTU Agriculture Soil Moisture Probe Sensor For Green House
The BGT-SM1(Z2) is a high precision and high sensitivity of soil moisture & temperature sensors. By measuring the dielectric constant of the soil, it shows stable real moisture content directly. The BGT-SM1(Z2) can measure the volume of soil moisture. The FDR soil moisture measurement method is in line with present international standards. Apply to the soil moisture monitoring, scientific experiment, water-saving irrigation, greenhouse vegetables, flowers, grass, fast measure, plant cultivation, greenhouse control, precision agriculture and the other measurement of water, weather or particulate matter content.
