Multi Depth Monitoring: Standard monitoring nodes include 10cm, 20cm, 30cm, 40cm depths, and different depths (e.g. 50cm, 60cm, 70cm, 80cm, 90cm, 100cm) and configurations can be customised according to requirements.
Durable material: Adopting special customised PVC plastic pipe, anti-aging and more resistant to corrosion of acid, alkali and salt in the soil; epoxy resin sealing material, no leakage in long-term immersion in water.
High accuracy and reliability: High measurement accuracy, less affected by soil texture, suitable for all kinds of soil texture; with multi-directional anti-wrong connection protection.
Flexible power supply: Support DC12~24V DC power supply and solar power supply.
Data transmission: Support RS485 digital output and GPRS wireless network data transmission (optional), which can realise remote data monitoring.
Simple installation: no on-site setting and calibration design, on-site installation at any time at any time to use.
Multi-directional protection against misconnection of power, ground and signal lines;
Multi Depth Soil Temperature Moisture Sensor Application Areas:
Multi Depth Soil Temperature Moisture Sensor is widely used in agriculture, forestry, environmental protection, water conservancy, meteorology and other industries for environmental information monitoring and collection.
