The probe material is made of 316 stainless steel, which is rust-proof, waterproof, anti-corrosion, salt-alkali corrosion resistance, and long-term electrolysis resistance. It is more affected by the soil salt content. It is small, can be buried in the soil for a long time, and is suitable for various soil types.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/dfimg.dfrobot.com\/enshop\/image\/cache3\/data\/SEN0600\/3_0x0.png.webp\" alt=\"Wiring Diagram of soil sensor and Arduino Uno\" title=\"Wiring Diagram of soil sensor and Arduino Uno\"\u003e\u003c\/p\u003e\n\u003cp\u003eWiring Diagram of soil sensor and Arduino Uno\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/dfimg.dfrobot.com\/enshop\/image\/cache3\/data\/SEN0600\/4_0x0.png.webp\" alt=\"Probe Material - 316 Stainless Steel\" title=\"Probe Material - 316 Stainless Steel\"\u003e\u003c\/p\u003e\n\u003cp\u003eProbe Material - 316 Stainless Steel\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eSoil sensors are widely used in agricultural irrigation, greenhouses, flowers and vegetables, grassland and pastures, soil rapid testing, plant cultivation, scientific experiments, grain storage and the measurement of moisture content and temperature of various particulate matter.\u003c\/p\u003e\n\u003cp\u003eSoil temperature has a direct impact on plant growth. Proper soil temperatures help promote plant root growth and the ability to absorb nutrients. Generally speaking, higher soil temperature is helpful for plant growth because it can increase plant metabolism, promote nutrient absorption and transport, and increase plant microbial synthesis capabilities, thereby promoting plant growth rate and yield.\u003c\/p\u003e\n\u003cp\u003eIn addition, appropriate soil moisture helps plant roots absorb water and nutrients and maintains water balance within plant cells. If the soil moisture is too low, plant roots will be limited in absorbing water, which can lead to plant dehydration, stagnant growth or even death. Excessive soil moisture may cause hypoxia in plant roots, hinder normal respiration and nutrient absorption of roots, and thus affect plant growth and development.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/dfimg.dfrobot.com\/enshop\/image\/cache3\/data\/SEN0600\/6_0x0.png.webp\" alt=\"How to install and use the soil sensor\" title=\"How to install and use the soil sensor\"\u003e\u003c\/p\u003e\n\u003cp\u003eHow to install and use the soil sensor\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eFor more detailed insights on selecting the most suitable sensor, refer to the guide on [\u003ca href=\"https:\/\/wiki.dfrobot.com\/How_to_Select_the_Best_Soil_Moisture_Sensors_for_Agriculture_and_Research_Lab\" target=\"_blank\"\u003eHow to Select the Best Soil Moisture Sensors for Agriculture and Research Lab\u003c\/a\u003e].\u003c\/p\u003e\n\u003cdiv id=\"Features\" class=\"content Features\"\u003e\n\u003ch4\u003eFeatures\u003c\/h4\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eWide Voltage Range:\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003eSupports 5-30V power supply.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRS485 Output:\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003eCompatible with Arduino and other systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFast Response:\u003cspan\u003e \u003c\/span\u003e\u003c\/b\u003eEnsures timely data retrieval.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eStainless Steel Probe:\u003cspan\u003e \u003c\/span\u003e\u003c\/b\u003eDesigned for long-term burial in soil or water.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eIP68 Protection Level:\u003cspan\u003e \u003c\/span\u003e\u003c\/b\u003eVacuum-filled and sealed with flame-retardant epoxy resin.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"Applications\" class=\"content Applications\"\u003e\n\u003ch4\u003eApplications\u003c\/h4\u003e\n\u003cdiv\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/dfimg.dfrobot.com\/enshop\/image\/cache3\/data\/SEN0600\/5_0x0.png.webp\" alt=\"Applications of RS485 Soil Sensor - Agricultural Irrigation, Greenhouses, Flower and Vegetable Cultivation\" title=\"Applications of RS485 Soil Sensor - Agricultural Irrigation, Greenhouses, Flower and Vegetable Cultivation\"\u003e\u003c\/p\u003e\n\u003ch4\u003eSpecification\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003ePower supply voltage: DC 5-30V\u003c\/li\u003e\n\u003cli\u003ePower consumption: 0.5W@24V\u003c\/li\u003e\n\u003cli\u003eOutput mode: RS485\u003c\/li\u003e\n\u003cli\u003eDetection parameters: Temperature, Humidity\u003c\/li\u003e\n\u003cli\u003eHumidity parameters\u003cbr\u003e         Measuring range: 0-100%\u003cbr\u003e         Resolution: 0.1%\u003cbr\u003e         Accuracy: 0-50%@±2%, 50-100%@±3%\u003c\/li\u003e\n\u003cli\u003eTemperature parameters\u003cbr\u003e         Measuring range: -40°C~+80°C\u003cbr\u003e         Resolution: 0.1°C\u003cbr\u003e         Accuracy: ±0.5°C\u003c\/li\u003e\n\u003cli\u003eProtection level: IP68\u003c\/li\u003e\n\u003cli\u003eProbe material: anti-corrosion special electrode\u003c\/li\u003e\n\u003cli\u003eSealing material: black flame retardant epoxy resin\u003c\/li\u003e\n\u003cli\u003eWorking temperature: -40°C~+60°C\u003c\/li\u003e\n\u003cli\u003eCable length: 2m\u003c\/li\u003e\n\u003cli\u003eSize: 123*45*15mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv id=\"Shipping-List\" class=\"content ShippingList\"\u003e\n\u003ch4\u003eShipping List\u003c\/h4\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003eRS485 Soil Sensor (Temperature \u0026amp; Humidity) x1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"Documents\" class=\"content documents\"\u003e\n\u003ch4\u003eDocuments\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/wiki.dfrobot.com\/sen0600\/\" target=\"_blank\"\u003eProduct Wiki\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"DFRobot","offers":[{"title":"Default Title","offer_id":41722610253957,"sku":null,"price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0565\/5819\/0725\/files\/2_6ef49073-53db-4fe8-b35d-7df453196193.png?v=1782132659","url":"https:\/\/robotpishop.com\/products\/rs485-modbus-rtu-ip68-soil-temperature-moisture-sensor-for-automatic-irrigation","provider":"Robot Pi Shop","version":"1.0","type":"link"}
