The 4 in 1 soil nutrient sensor solves the problem that users need to purchase multiple soil sensors to measure different soil elements. The soil nutrient sensor consists of five stainless steel probes, which are used to measure soil moisture, temperature, electrical conductivity, and pH. You can select one or more soil elements to measure or test all soil elements at the same time. The flexibility is very high. The housing of the integrated soil nutrient sensor is sealed with epoxy resin vacuum, completely waterproof, with IP68 protection class. It can be used outdoor for a long time. It is resistant to electrolysis and corrosion. The service life is up to 3-5 years. Parameters: Power supply: DC 4.5-30V Maximum power consumption: 0.5W (24V DC power supply) Working temperature: -20℃~+60℃ Core chip temperature resistance: 85℃ Protection grade: IP68 Probe material: Anti-corrosion special electrode Sealing material: Black flame-retardant epoxy resin The default cable length: 2 meters, the cable length can be customized as required Dimensions: 45*15*123mm Output signal: RS485 Technical characteristics: Temperature Range: -40~80℃ Accuracy: ±0.5℃ (25℃) Resolution: 0.1℃ Moisture Range: 0-100% Accuracy: 0-50%≤ 2%, 50-100%≤ 3% Resolution: 0.1% EC Range: 0-20000μS/cm Accuracy: 0-10000μS/cm ≤±3%FS, 10000-20000μS/cm ≤±5%FS Resolution: 1μS/cm PH Range: 3~9PH Resolution: 0.1 Advantages of soil nutrient sensor: High quality The electrode is made of specially treated alloy material, which can withstand strong external impact and is not easy to damage.
